BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a database system for registering objects to be registered as data comprising category names, individual title names, and their actual contents. And a system that can be applied as an online database that can be registered and viewed from the client side.
2. Description of the Related Art With the widespread use of information devices such as personal computers and the expansion of online services through networks such as the Internet, the number and types of databases used for the past several years have jumped. Are increasing. Traditionally, database models include network, hierarchical, relational, and object-oriented models.Relational databases (Relationa
l Database; hereinafter referred to as “RDB”).
Object-oriented Datab
ase; hereinafter, referred to as “OODB”) is an object-oriented approach that is becoming the mainstream of software development techniques, incorporated into a database system, and its development and implementation are urgent. Further, the construction of an object relational database (ORDB) incorporating object orientation into the RDB is also active.
[0003] Here, the RDB expresses data using a two-dimensional table (table) composed of rows and columns and the relationship between the tables. It has features that the structure of the data model is easy to understand and the design is relatively easy. Also, RDB
In normalization, normalization is performed as a method of reducing data redundancy (reducing data duplication) and simplifying search and update by using a lean table structure. 1st to 3rd normal form, extended 3rd normal form of Boyce / Codd, 4th normal form by R. Fagin, etc.), and the most efficient table structure can be obtained based on those criteria. It has become. Furthermore, a common access language SQL (Structure Query Language) is standardized, and has an advantage that data can be extracted without describing a procedure by passing through an engine for decoding the SQL sentence.
On the other hand, the OODB manages an object in which data and procedures (methods) related to the data are integrated, and a program is described by describing the exchange of instruction commands and data (messages) performed between the objects. Things. Objects of the same type are grouped as a class (functions and attributes common to the objects are abstractly defined), and a method of a higher class is inherited by a lower class.
In OODB, there are many types of data structures,
By encapsulating data and methods as described above, it is possible to realize a direct and easy-to-understand operation environment as well as to handle real things, and to store not only letters and numbers but also images and sounds There is. Note that object-oriented languages include C ++, Smalltalk, and Java.
By the way, in the RDB, the table structure is designed according to the above-mentioned standard form standards. However, those standards are merely logical systems, and a large number of file groups are practically used. Since each table is created sequentially while being made into a figure, the design of the table structure involves a very complicated operation, and often requires a huge amount of time and labor. Also, in a database that handles a wide range of objects, there are an extremely large number of table groups, which must be managed for each table group. In many cases, changes need to be made to the set of tables and programs that have been set, and the reorganization work for that is also extremely difficult.
Next, regarding OODB, since data and methods for individual registration targets are encapsulated in the object, for example, when there is a change in the items or data of the employee database, You must open the employee's object and make changes one at a time, carefully considering whether it will affect the inherited class when it is associated with a method, and is generally more complex and difficult than with an RDB Programs are often forced to be reorganized.
In other words, OODB is basically aimed at an efficient operation environment of the user interface, and the programming efficiency is improved in that the method can be inherited. It requires a high degree of experience in the accumulation and management of messages and the programming of messages, and when the data is enormous, the amount of work required for maintenance becomes much larger than in the case of RDB. Further, regarding ORDB, since it is basically a hybrid type of RDB and OODB and has a more advanced and complicated configuration, the RDB and OODB are also used.
It will have the problem of DB.
Therefore, the present invention has only a very simplified table structure while handling registration objects of all categories, and performs the functions essential for a database such as data input, storage, retrieval, and output with a small scale of software by using small software. A database system that can be executed in a flexible manner and can respond very easily to changes in the items to be registered, etc., solves the above-mentioned problems of RDB and OODB, and has a low construction cost and operation cost. It was created to provide a highly functional database that can be dramatically reduced. Further, the database system of the present invention enables free data registration in an interactive manner from the client side through a communication line such as the Internet without the intervention of a programmer, and the convenience as a user interface of OODB is at the same level. This is what we are trying to achieve.
According to a first aspect of the present invention, an object to be registered is provided.
While managing category names and their hierarchies, which are abstract concepts of (events or things), in a data dictionary file, in a database system that registers the category names, individual title names, and their substantive contents of each registered event, data cells A first table and a second table are provided, and the first table and the second table are provided.
In the table, category identification information given in the data dictionary file is stored in a data cell in a specific column, and attributes and / or attributes of the category are stored in other data cells belonging to a row in which the category identification information is stored. or
Attribute (hereinafter, referred to as "item data attributes") data in representing the substantive content of the engaging Ru item name and the item to each item representing at features androgynous causes the store, the second
The table, dissipate stores category identification information and title name to each data cell of the particular two rows, other <br/> each data cell which belongs to that category identification information and line the title are stored, each the substantive content of the item name to be stored so that the row direction sequence identical order of the data cell that contains the item names and item data <br/> attribute that put in the first table with respect to item name According to a database system, each method for inputting, storing, searching, and outputting data relating to a registration target is generated based on data stored in the first table.
In the first invention, data to be registered belonging to all categories is managed by two simple tables. In the first table, the category identification information to be registered and each [item name and item data attribute] related to the category are registered in each data cell in row units, and in the second table, the category identification information, title name, and registration are registered. The substantive contents of each target item name are registered in each data cell on a row-by-row basis. Both registered data are associated with the category identification information, and the [item name and item data attribute] and “each "Substantial contents related to item names" are associated with the item names in the row direction of each data cell.
The first table is a virtualized version of [substantial contents relating to each item name] in the second table in a data format of [item name and item data attribute]. It becomes possible to register and manage the data to be registered in a single second table, and based on the property of the "item data attribute",
Methods for executing the functions of input, storage, retrieval, and output, which are indispensable for the database system, can be generated simply by providing one process control program for each function. That is, the conventional database system configures a large number of tables with a complicated relationship, and corresponds to each control program for executing each of the above-described functions. Although a large number of programs such as various join programs are required in consideration of the above, a similar database system can be constructed only with a very simplified table structure and small programs.
The above-mentioned first invention can be configured as the following second invention in consideration of operational aspects. The second
In the invention, an input field for a category name, which is an abstract concept to be registered, an input field for each item name representing an attribute and / or a function related to the category, and an item data attribute related to the item name are defined for each item. The first storage means stores a first registration screen in which input fields for inputting are arranged, a first display means for reading out and displaying the first registration screen in the first storage means, and a data cell. and a first table, the data cell of a specific column of the first table as a storage area of said data dictionary file category identification information given by, the item names and item data attributes for each data cell of other columns assigned as <br/> storage area, based on an input to each input field of said first registration screen, the first registration means for registering the category identification information and item names and item data attributes in units of rows The said Generates a display method based on the row direction data for the category name in the table, and arranges a title name input field for registration target, a display field for each item name, and an input field for substantive contents for each item name Display means for displaying the second registration screen, a second table composed of data cells, and storage areas for category identification information and title names, each of which is a specific two-column data cell in the second table. Each data cell in the other column is allocated as a storage area of substantive contents related to the item name, and based on the input in each input field of the second registration screen, category identification information, title name, The substantive contents related to the item names are stored. In the storage, the row direction order of each data cell in which the substantive contents related to each item name is stored is determined by the first table with respect to the item names. And second registration means for setting so that the row direction sequence identical order of the data cell that contains the item names and item data attributes that put Le, when there is contact by various conditions, the data Based on the registered data of the first table associated from the dictionary file, an access method to the second table according to the query condition and an output method of the registered data obtained by the access are generated, and the method The present invention relates to a database system having a data output unit for outputting registered data relating to an inquiry.
In the second invention, the first storage means and the first display means display a first registration screen corresponding to a guidance screen, so that a category name, each item name, and an item for each item name are displayed. Enter data attributes. The first registration means causes the input data to be stored in each data cell of the first table in units of rows based on the input on the first registration screen, but the second table is stored in a data format of [item name and item data attribute]. [Substantive contents relating to each item name] stored in the file is virtualized. The second display unit displays a second registration screen corresponding to a guidance screen for inputting a title name to be registered, each item name, and substantive contents related to each item name. In this case, the second display means can generate a display method of the second registration screen from the row direction data related to the category identification information based on the table configuration based on the virtualized data of the first table. Therefore, the data registered in the first table plays a role in defining the display condition of the second registration screen by the second display means. The second registration unit causes the input data to be stored in each data cell of the second table together with the category identification information in a row unit based on the input on the second registration screen. The association between the registration data of the first table and the registration data of the second table is set as described in the first invention. Therefore, the data registered in the first table has a role of defining the storage condition of the substantive contents for each item name related to the registration target for the second registration means. The data output means accepts an inquiry to the database system for registration. There are various query conditions, such as a search using a category name or a title name as a key, a search using a substantive content related to an item name as a key, and a search that narrows down the substantive content. An access method for the second table is generated by obtaining registration data of the first table associated with the data dictionary file according to the search condition, and the registration data is used. An output method is generated based on the registration data of one table. Therefore, the data registered in the first table plays a role of defining a search condition and an output condition for this data output means. As described above, the second invention is the first invention.
While giving the registration screen and the second registration screen as guidance screens, the user registers the data in the first table and the second table, and manages the registration data to be registered in the two tables (input, save, search, Output), which are enabled based on the virtuality of the first table. The virtuality also effectively functions in generating the second registration screen. In other words, in the conventional database, when it is necessary to register a new category, a programmer has designed a complicated table structure and created a huge number of programs. For example, after registering the category name, each item name, and the item data attribute for each item name in advance according to the guidance, the simple procedure of registering the title name to be registered and the substantive contents of each item according to the guidance is followed. In response to individual instructions relating to input, storage, retrieval, and output, a program is automatically developed in real time and operates as if it were driven, thereby realizing a system that can be called a "virtual object" oriented database.
In the first and second aspects of the present invention, if a data type is provided as a definition item of the data attribute, the input / save / search / output functions can be executed. It is desirable to provide a data size in advance. If the data size is not defined, the data amount of the substantive contents related to each item name to be registered in the second table often differs for each item, and the capacity of the data cell is set to its maximum value. Then, a large waste of memory occurs. Therefore, as described above, if the data size is defined in advance and each data cell of the second table can be variably set to a required capacity, the problem can be solved. If the categories are the same,
Based on empirical rules, the data amounts of the substantive contents of each item name are almost the same.
[0015] In addition to the above data type and data size, if the unit and range can be defined, attributes and functions of each item of any object existing in the natural world can be appropriately expressed and registered. Procedures can be simplified and registration contents can be enhanced.
Next, if a selection menu of a character type, a number type, a date type, an image type, and a voice type is provided as the data type, the expression method of the substantive contents related to each item name is covered. Can be covered.
Further, if a selection menu is provided to indicate that the data is obtained by linking with another application and / or another system, together with those basic data types or as an independent data type, A wide variety of data existing outside the system can be freely imported and registered, making it possible to use it as a data warehouse and build a distributed database.
In the second aspect of the present invention, the capacity of the data cells in the second table can be variably set based on the data attributes defined in the first table as described above. When the substantive contents are input in a data type such as an image type or a sound type, the data amount becomes extremely large as compared with a character type or a date type.
On the other hand, the capacity of the data cells of the second table may be limited due to the characteristics of the system, and from the viewpoint of data management, there is no significant difference in the capacity of each data cell on the table. Not preferred. Therefore,
In such a case, data of substantial contents is stored in a large-capacity second storage means provided separately, and only the corresponding address of the data stored in the second storage means is registered in the data cell of the second table. By doing so, the above problem can be solved.
Further, in the second invention, the first storage means stores a first registration screen provided with an input field relating to the display order in correspondence with the input field of each item name. The display order thus obtained is added to the item data attribute corresponding to each item name and stored in each data cell of the first table, and the data output means determines the display order of the substantive contents related to each item name according to the input. If the output method set based on the display order is generated, the display order of the substantive contents relating to each item can be arbitrarily set in advance, and when the searched registration target is displayed, In addition, it is possible to output not only uniform registration information but also a display image having a layout adapted to a category.
In a third aspect, the second aspect is an online
It relates to the configuration when applied as a database system. According to the present invention, a line connection with a client side is performed in response to a connection request transmitted from the client side on a network, and a first registration screen is provided by the first display means in response to a registration request from the client side. Registering the input data in the first table based on transmission of the input data to the first registration screen by the client side; and registering the input data in the first table based on the registration data related to the category identification information in the first table. (2) providing the second registration screen by the display means to the client side, and registering the input data in the second table based on transmission of the input data to the second registration screen by the client side; Various screens for inquiry prepared in advance based on the inquiry of the It said data output means in response to an inquiry conditions in which to provide the registration data of the second table to the client. In this case, the traditional online database is simply browsing and
Instead of having only a search function, it becomes possible to register registration targets of all categories in the database very easily while receiving guidance online.
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a preferred embodiment of a database system (hereinafter, referred to as "DBS") of the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a system configuration diagram of an online DBS to which the present invention is applied. In FIG. 1, reference numeral 1 denotes a DBS, 2 denotes the Internet, and 3-1 to n denote clients (terminals such as personal computers) connected to the Internet 2 via a modem and a browser (Web browser). Here, DBS1 is a database management system (hereinafter referred to as "D
BMS) 10 is connected to the Internet 2 via a communication control device 11 such as a router and a Web server 12, and the DBMS 10 is connected to a hard disk device (hereinafter, referred to as "HDD") 13 for data registration. File server 14
And a management personal computer 15 is connected.
The DBS 1 stores various screen data 18 related to a function menu of the system in the HDD 13 and a normal DB
A category hierarchy management table (hereinafter, referred to as “CLMT”) 19 corresponding to the data dictionary file in S, and data properties (hereinafter, referred to as “DP”) setting screen data
20; a DP table (hereinafter, referred to as "DPT") 21; and a main data table (hereinafter, referred to as "MDT") 22.
This is a system that can register data in DD13 and search and browse the data. In particular, while handling data of registration targets (events or things) belonging to all categories, regarding the processing of registration data, DPT21 and MPT
The feature is that the DBMS 10, which is a tool for managing and maintaining the registered data, which is supported by the two tables of DT22, can be configured with extremely simplified software.
It is based on a unique concept completely different from the conventional DBS. Therefore, here, in order to clarify what rationality of those features is realized, the handling of the categories in this DBS1 will be conceptually described in advance, and the data “registration (DP setting registration / main data Registration)), (viewing (search / output)), (change (update / delete)), and (addition / deletion of category-related items) will be described sequentially with reference to flowcharts and various display screens. .
1. 2. Handling of Categories In this DBS1, as shown in FIG. 2, information to be handled is classified into "@ electronic bulletin board", "@ electronic catalog", "@ company information", "@ member management", and "@ news". . Here, “■ electronic bulletin board” is a section provided for use as a bulletin board in which the client 3 can write and publish various information, and “■ electronic catalog” is a section for publishing the product information of the client 3 in a catalog format. , “■ Company information” is a category for disclosing company information and stock information,
“■ Member management” is a section for managing information of members who use this system, and “■ Notice” is a section for disseminating information notified / provided by the administrator of this system. It is an example, and various sections can be provided as needed.
Then, as the registration of data into the DBS 1 progresses, various categories of hierarchies are formed below these divisions, and FIG. 2 shows an example of the state. In the figure, the upper category indicated by □ is DB
The administrator of S1 decides on his own or client 3
The category indicated by ◇ is DBS1 as described above.
Can be set, but the client 3 can freely select and set it mainly when performing the data registration procedure, and the DP setting and registration for the DPT 21 are performed at the category level. Although FIG. 2 shows only the category level up to ◇, a lower category level can be provided if necessary.
On the other hand, in this DBS1, the hierarchical structure described above is changed to a CLMT19 composed of data cells as shown in FIG.
Managed by Here, in the column of CATG_KJ (category name), each section in FIG. 2 is also regarded as a category level, and each category name belonging to a lower level is stored in an individual row together with them, and the column of CATG_NO (category number) is A number corresponding to each category name is stored on the same line as category identification information, and the category number is sequentially assigned each time a new category name is added. Also, the column of ROOT_CATG_NO (category number of route) is ■ Electronic bulletin board / ■ Electronic catalog /
■ Company information / ■ Member management / ■ Information categories are 1/2/3/4/5 as the highest category level.
The PARENT_CATG_NO (parent category number) column indicates the category number of the category name that is higher than each category name. It is. still,
Since there is no higher-level category for each of the above sections, their PARENT_CATG_NO is 0. Therefore, by referring to the CLMT 19, it is possible to confirm the division and the hierarchy of each category name.
2. Data registration procedure In this DBS1, registration of main data in the MDT 22 is performed on the premise that DP settings are registered in the DPT 21. Whether or not the client 3 continuously performs the registration procedure is optional, but since the data registration process in the system is independent, each registration procedure will be described separately here.
(1) DP setting registration procedure This registration procedure is shown in the flowchart of FIG. First, the client 3 connects to the DBS 1 via the Internet 2.
When the connection is made, the DBMS 10 reads out the member confirmation screen data (18) from the HDD 13 and sends it to the client 3 side,
The client 3 inputs an ID and a password in a predetermined portion of the screen and transmits the ID and the password to the DBS1 (S1 to S3). When the DBS 1 confirms the identity of the member by ID or password, the system is opened to the client 3 and the HDD 13
Then, the function menu screen data (18) is read out and transmitted to the client 3 side (S4, S5). The function menu screen provided to the client 3 is a screen for selecting various functions of the DBS 1 such as “setting of DP” and “registration of main data”. Then, on the screen, "DP settings"
When the menu is selected, the section list screen is displayed as the initial screen
(With guidance to the lower hierarchy) is provided, and a selection screen for an upper category belonging to the lower hierarchy of the category is provided by an instruction operation on the client 3 side (S5). Note that these screens are configured in a list display or tree display format.
It is generated by the MS 10 based on the management data of the CLMT 19.
When “DP setting” in the upper category is selected on the client 3 side, in the DBS 1, the DBMS 10 reads out the DP setting screen data 20 of the HDD 13 based on the selection and transmits it to the client 3 side. Do
(S6, S7). Here, the screen provided and displayed to the client 3 based on the DP setting screen data 20 has a configuration as shown in FIG. As shown in the figure, the screen includes an input field for a category name, which is an abstract concept to be registered, an input field for each item name representing an attribute or / and a function related to the category, and an input field for each item. And an additional memo field for inputting a data type when expressing the substantive contents according to the above. Although omitted in the figure, input guidance is written in a region surrounded by a dotted line. As other fields, numbers are previously entered in the display order input field, but these are given as initial values and can be rewritten, and the input style and display style fields will be described later. The style code assigned on the DBS1 side is input. The data registration column is a column for selecting whether or not to register main data under the category name and indicating the intention.
When the above-mentioned DP setting screen (FIG. 5) is displayed on the client 3 side, the name of the category to be registered (the category belonging to the upper category selected in S5) and each item name are input. At the same time (and, if necessary, changing the display order), a data type for expressing the substantive contents of each item name is input (S8). In that case,
In the input of the data type, by clicking a button provided on the right side of each input column, a pull-down menu as shown in FIG. 9A appears, and the user can select from the menu. Then, enter each item name and its data type and click the "Next" button in the lower column. In the notation area of the input guidance, the maximum number of characters, unit, and range can be specified according to the specified data type. And input fields for search specification (designation of search target or not) and list display (designation of list display target) are individually displayed.
For example, when the upper category is selected as [pet animal] and the category name is [dog], as shown in FIG.
Assuming that weight / body height / male / female / special skill / favorite / pedigree / owner / photo has been input, character / numerical / numerical data types are used as data types for expressing the substantive contents of those items. When the / number type / character type / character type / character type / character type / character type / image type is set, a pull-down menu as shown in FIG. 9B is displayed in the column of the maximum number of characters for the character type. Is displayed, and for numeric types, it is assumed that it is within 64 characters,
Instead of leaving the column with the maximum number of characters blank, an input box for specifying the unit and range is displayed.
All are blank because there is no need to define the unit / range specification. For the range designation, a pull-down menu as shown in FIG. 9C is provided. Then, on the client 3 side, the required input is performed in the input fields provided in the columns of the maximum number of characters, the unit, the range specification, the search specification, and the list display, but when the unlimited character type is selected, the line as a rough guide is used. An input field of “number × column number” is displayed, and input is also performed in that field. The screen shown in FIG. 6 is a state where the input to the DP setting screen related to the category name: [dog] is completed.
On the other hand, in the screen for two pages in FIGS. 7 and 8, the input to the DP setting screen is completed when [Telecommunication Terminal] is selected as the upper category and the category name is [General Telephone]. Although the number of item names is larger than that in the case of category name: [Dog], it is input through the same procedure. In this case, the date type is selected as the data type of the date of the certification date, and based on the selection, the input field for displaying the pull-down menu as shown in FIG. However, an input field for displaying the pull-down menu of FIG. 9C is displayed in a column for specifying a range, and required inputs are made for each.
On the DP setting screens (FIGS. 6 to 8) relating to each category name, Plugin / voice type / E-mail / URL among the data types shown in FIG. Link/
Download / Password / System link is not selected. "Plugin" is video data, "Audio" is audio data, "E-mail" is email data,
"URL link" is homepage data on Internet2, "Download" is Internet2 or LAN
Data downloaded from (Local area network)
`` Password '' is a password used when browsing the registered substantive contents, `` Link between Systems '' is intended to capture data of other systems and applications, and the same applies to the above image type However, when registering the actual contents of the main data later, a unique wizard or a special notation format (**** format for password) is required.
As described above, the client 3
When the input on the P setting screen is completed, the content update button is clicked and transmitted to DBS1 (S8). Meanwhile, DB
Upon receiving the setting data from the client 3, the MS 10 registers the category name in the CATG_KJ of the CLMT 19, adds a serial number to the CATG_NO, and
OOT_CATG_NO and PARENT_CATG_NO are also assigned respective corresponding numbers and stored (S10). For example, as shown in the above case (DP setting in FIG. 6), when the category name is [dog] and it is the first registration related to the category name, as shown in FIG. CATG_KJ is registered as [dog], and CATG_NO is registered as "1" as a serial number.
"6" is stored, and "1" is stored in ROOT_CATG_NO because it corresponds to registration in the "@ Electronic bulletin board" category, and PAREN
T_CATG_NO stores “15” corresponding to the CATG_NO since the upper category was “pet animal”. Also, as in the DP settings in FIGS. 7 and 8,
If the category name is the first registration related to [general telephone], CATG_NO indicates "1" as the serial number.
8 ”is stored, and“ ■ Electronic catalog ”is stored in ROOT_CATG_NO.
"2" is stored because it corresponds to registration in the category of PAR
Since the upper category was "telecommunication terminal", "11" corresponding to the CATG_NO is stored in ENT_CATG_NO. In addition, in CATG_KJ of CLMT19,
Even if the same category name already exists, if there is a request for DP setting registration, it will be registered by giving CATG_NO, but the registered category name will be "dog / 1" It is registered with a name that is distinguished from the previous "dog" (see CATG_NO; 21 in FIG. 3).
Next, the DBMS 10 stores and registers the received DP setting data in the DPT 21 (S12). The DP
The registration method for T21 is shown in FIG. First, DP
T21 is a table composed of data cells, DBM
In S10, the first column is used to store the above PARENT_CATG_NO,
The second column is for storing the above-mentioned CATG_NO, and the third and subsequent columns are for [Item name and display order, data type, data size, unit, range specification, search specification, list display] of the DP setting data. Allocated for storage. In this embodiment, the data cell numbers in the third and subsequent columns in the DPT 21 are given in ascending order from (1).
In the following description, [display order, data type,
Data size, unit, range specification, search specification, list display]
Are collectively referred to as “item data attributes”, and when only [data type / data size / unit / range designation] is collectively referred to as “item data attributes”.
The DBMS 10 stores the PARENT_CATG_NO and the CATG stored in the CLMT 19 based on the above-mentioned allocation standard.
[Item name and item data attribute, etc.] of the received DP setting data are stored in each data cell together with each number of _NO in units of rows (S12). As a result, if the received setting data is category name [dog] or category name [general telephone], FIG.
0, the registration format is the same for all other category names, and the DP setting data of one category name is always registered in one line of DPT21. . Then, the registration data of each line of DPT21 is C by PARENT_CATG_NO and CATG_NO.
This is associated with the division, higher-level category name, or category name registered in CATG_KJ of LMT19.
The category name for which registration has been requested already exists in the CLMT 19, and its DP setting data is
In the state registered in T21, a registration request for the same category name may be made. In such a case, in the DBS1, independent and independent registration processing is performed regardless of whether or not [item name and item data attribute, etc.] are the same. However, since the category name is the same, The identification name is added to the category name related to the registration request, such as “part 1”, “part 2”, and the like, and stored in CATG_KJ of CLMT19. For example, in CLMT19 of FIG. 3, CATG_NO is "16".
CATG_KJ: "dog" and CATG_NO are "21" CATG_KJ: "dog
It is due to the above-mentioned processing that CATG_KJ: “general book” has a similar case. In these cases, when the [item name and item data attribute, etc.] are all the same or have a common part, the information is added to the CLMT19 additional information column (CATG_FIG. 3 in FIG. 3).
(Column after KJ) and use it for later list display and search procedure. This DBS1
Employs the processing method described above, but it is also possible to adopt a method in which only one registration is permitted for one category name.
(2) Main data registration procedure The main data registration procedure is shown in the flowchart of FIG. The registration data in the DPT 21 is not the substantive data to be registered, but the “category name”, the “item name of the attribute or / and the function”, and the “attribute possessed by the data expressing the substantive contents related to the item name”. Is virtualized. However, since it is virtualized data, it functions extremely rationally when registering the substantial contents of the main data in this registration procedure.
First, when the client 3 connects to the DBS 1 via the Internet 2 at the time of registration of the main data, the function menu screen (18) is provided through the same procedure as in the above-mentioned "DP setting". In this case, the client 3 selects the "Register main data" menu from the screen (S21 to S25). And also in this case,
The DBS1 provides a section list screen as an initial screen based on the selection of the function menu, and the client 3 sequentially moves to the lower hierarchy in the order of category → higher category → category by an instruction operation from the same screen, and moves to each level. Is provided, and a category selection screen is finally displayed on the client 3 side (S25). In other words, the client 3 sequentially designates the category and the upper category related to the current registration target, and selects a required category from the categories registered in the above-described DP setting registration procedure.
When the DBS 1 receives the category selection data and the main data registration request, the DBMS 10 generates registration screen data of substantial contents relating to the selected category and transmits it to the client 3 (S26, S27). . If the registration screen is, for example, a category name [dog], FIG.
13 and FIG. 14 for the category name [general telephone], the input fields other than the code number are blank on the registration screen transmitted. It has become. Specifically, as shown in each figure, the registration screen includes a title indicating that it is an input screen for registration data specifying a category name, a code number display field, and a title name input field for registration. And an input column for substantive contents of each item name and the corresponding item.
Here, the transmitted registration screen data is
The DBMS 10 uses the selected category name as a key for CL
The CATG_KJ of the MT19 (FIG. 3) is searched, and the CATG_KJ of the DPT21 (FIG. 10) is searched using the CATG_NO corresponding to the category name as a key.
This is obtained by searching for NO and generating a display method based on [item name and item data attribute] stored in each data cell in the row direction corresponding to the same number in DPT21. This is apparent from a comparison of FIGS. 6, 10 and 12 for the category name [dog] and FIGS. 7 and 8 and FIGS. 13 and 14 for the category name [general telephone]. As described above, the entry fields of the substantive contents relating to each item of the registration screen are configured with the size, unit, input method, etc. corresponding to the item data attribute of the DPT21, and the substantive contents of the registration target are displayed on the client 3 side. It is possible to provide an easy-to-understand screen when inputting.
Further, the DBMS 10 makes preparations for storing the substantive contents of the registration target received later in the MDT 22 (S28). That is, in order to secure in advance the capacity of the data cell in the row direction in which the substantive contents to be registered later are registered, the MDT 22 is determined based on the data type and the maximum number of characters of each item of the DPT 21 related to the category name. Are sequentially set.
On the client 3 side, FIG. 12 (category name [dog]
) And desired substantive contents relating to each item name as shown in FIGS. 13 and 14 (in the case of the category name [general telephone]), and the “registration processing” provided in the lower column. By clicking the button, the input data is transmitted to the DBS1 side (S29). However, if the item name is photo and the data type is image type, an image registration button will be displayed next to the input field on the registration screen, and clicking that button will download the image data. A wizard for instructing is started, and the image data is taken in as registration data according to the instruction. The same applies to the case where the data type is Plugin / voice type / download / system link as described above, and data capture is performed based on each wizard.
On the other hand, the DBS receiving the registration data
On the first side, the DBMS 10 sets the CATG_NO
The title, the code number, and the substantive contents of each item are stored and registered in each data cell of the MDT 22 in units of rows.
(S30, S31). FIG. 15 shows a data registration method for the MDT 22. First, the MDT 22 is a table composed of data cells, and the DBMS 10 stores the first column as the row number, the second column as the storage for CATG_NO, the third column as the storage for the title name, The fourth column is for storing code numbers,
The fifth and subsequent columns are assigned to store substantive contents relating to each item name. In this embodiment, the fifth
The data cell numbers in the columns and thereafter are given in ascending order from (1). Then, the DBMS 10 sequentially stores the substantive contents relating to each item name in the data cell having the same number as the data cell number of the DPT 21 in the MDT 22. In particular,
In the case of the registered data of the category name [dog] and the title name [amber], as shown in the row of No. 148 in FIG.
The data cell in the column of O stores “16” which is the category number of [dog] in advance, and the data cell in the column of the title name is [amber] and the data cell numbers are given in ascending order. In the cell, the substantive contents related to the item name of type / age / weight / body height ... are stored. No.287 is also used for the registered data of category name [general telephone] and title name [T-3360 telephone].
, Each data is stored in the same manner.
The capacity of each data cell is determined in advance in step S28.
Is set to a size that can store each substantive content.
However, for example, the title name [T-336 in FIG.
The data cell number (4) in the row of No.287 related to [0 telephone]
"IMAGE FILE No.43" data is stored. This is because, as shown in the DP setting screen (FIG. 7), the configuration of the DPT 21 (FIG. 10), and the registration screen (FIG. 13), the data cell number (4) of the row of No. The data type is set to image type, and the image data of the photograph should be stored. The client 3 clicks the “image registration” button on the registration screen of FIG. The image data was registered in accordance with the wizard. The DBMS 10 stores the image file in the HDD 14a of the file server 14, and the data cell of the MDT 22 stores "IMAGE FILE No. 43 ".
That is, in the DBS 1 of this embodiment, in order to avoid a large imbalance in the amount of data stored in each data cell of the MDT 22, the data type is an image type or a plug-in.
If the data type is "/ voice type" / "download", the data is stored as a file in the file server 14, and only the file number is registered in the data cell of the MDT 22.
Thus, the DBS1 of this embodiment is
As shown in FIG. 15, the registration target related to various categories besides [dog] and [general telephone] is registered in the MDT 22, and the substantial contents stored in each data cell of the MDT 22 are as follows. It is associated with the item data attribute stored in each data cell of the DPT 21 having the same number as the data cell. And, in the DBS1 of this embodiment, FIG.
As shown in FIG. 5, the point that the MDT 22 which is a single table registers the substantive contents to be registered belonging to all categories, and that the DPT 21 It is characterized in that the table is configured in a virtualized format called the item data attribute. In the DBS 1 of this embodiment, the table structure is extremely simplified due to these characteristics, and the following items “data browsing (search / output)”, “data change (update / delete)”, “category items” The program for executing each of the steps of "change" can be made very simple.
3. Data browsing (retrieval / output) procedure First, in the DBS1 of this embodiment, the client 3 makes an appropriate selection from among the section list and various screens provided from the DBS1 and obtains a higher-level data as shown in FIG. Category list is provided. However, the browsing of this data is open to the general public due to its nature. Naturally, regardless of whether or not the client 3 is a member, transmission of the member confirmation screen and transmission of the ID / password in the above-described registration procedure are performed. No entry procedure is required. The screen of the upper category list shows DMT for each category name of CLMT19.
Based on the upper category name or information category given by the administrator of BS1, the presence / absence of the lower category, a selection box for whether to see the list data of the lower category, and the outline of the registration data included in each upper category are described. To display. And, for example, the upper category name on the screen
When the user selects “view list data” for [pet animals], a list display screen in a tree display system as shown in FIG. 17 is provided. These display screens are configured by the DBMS 10 by referring to the CLMT 19 and the DPT 21 and using a predetermined display method.
Here, the search procedure when “view dog list data” is selected on the tree display screen of FIG. 17 will be described first. The search procedure is shown in the flowchart of FIG. Once the selection is made, the DBMS
10 starts the category-designated data list display program (S41, S42), searches CATG_KJ of CLMT19, and confirms CATG_NO; "16" corresponding to [dog] (S43). Next, DB
The MS 10 searches the second column (CATG_NO column) of the DPT 21 (FIG. 10), reads out the setting data in the row direction corresponding to the number “16”, and immediately generates a display method using it as a message. The layout data of the data list of the category [dog] is generated (S44). Next, the DBMS 10 searches the second column (the column of CATG_NO) of the MDT 22 (FIG. 15),
All the registered data in the row direction corresponding to the number “16” are read, and the read data is written into each predetermined portion of the previously generated layout data to create display screen data (S45).
In this case, CAPT is used in DPT21 of FIG.
_NO is “16”, the row direction setting data and M in FIG.
As is clear when comparing the registered data in the row direction where CATG_NO is "16" in DT22, the category name is associated with CATG_NO: "16" and each item name on the DPT21 side is And item data attributes etc.]
Since the substantive contents relating to the respective item names on the MDT 22 and the MDT 22 are associated with each other by the data cell numbers in both tables, an extremely simple program for creating the display screen data is sufficient.
Then, the created display screen data is transmitted to the client 3 side, and displayed as a data list of the category [dog] as shown in FIG. 19 on the client 3 side (S46). In the table of FIG. 19, the item columns of “special skill”, “favorite food”, and “photo” are each displayed as “separate window display” because the item data attributes in the DPT 21 are large. It indicates that
This is because, in the case of a list, it is considered that an area to be specifically displayed cannot be secured.
In the above description, the category name is limited to “dog”. However, as described in the DP setting registration, the category name related to the registration request after the same as the existing category name is set. "Part 1", "part 2"
An identifier is added and registered in the CATG_KJ of CLMT19 as shown in... When the [item name and item data attribute, etc.] are all the same or have a common part, the information is stored in the additional information column. I have to. Naturally, the main data is also registered for the category name to which the identification word is added. In this DBS1, when displaying a data list of the category [dog], in principle, [dog] and [dog / part 1] having different category names are displayed as separate lists, When the additional information is stored as described above, all or a part of the registered data relating to [Dog / Part 1] is incorporated and displayed in the data list of the category [Dog] using the information. Is also possible.
Next, in the DBS1, in the data list of the category [dog], the corresponding data is provided by clicking on each title name or each window display underlined.・ It can be displayed. In particular, if a browsing request is made by clicking an individual title name portion, the registered items of the title name can be searched, and an answer screen including all substantive contents can be displayed.
Therefore, here, the above category [dog]
The procedure for obtaining an answer screen when there is a browsing request specifying the title name "Amber" in the data list of
This will be described with reference to the flowchart of FIG. First, when a click with the title "Amber" is made on the screen shown in FIG. 19, the DBMS 10 activates the content display program of the search data (S51, S52). And DB
The MS 10 searches the CATG_KJ of the CLMT 19 (FIG. 3) based on the program, and confirms the CATG_NO; “16” corresponding to [dog] (S53). Also, DPT21
The CATG_NO of FIG. 10 is searched, the setting data in the row direction corresponding to the CATG_NO; “16” is read, and a display method using the message as a message is immediately generated to generate the layout data of the answer screen related to the category [dog]. It is generated (S54). In this case, the layout data is generated based on the item data attributes and the like stored in the data cells (1) to (11) related to the category name [dog] of the DPT 21 (FIG. 10). The item data attributes and the like give the display order of the substantive contents relating to each item name and its expression method as data, and the program merely executes the layout design automatically using the data.
Next, the DBMS 10 stores the CA of the MDT 22 (FIG. 15).
Search the column of TG_NO and the column of title name, CATG_NO is "16"
In step S55, the row direction data having the title "Amber" is read, and the read data is written into each predetermined portion of the previously generated layout screen data to create answer screen data. Then, the DBMS 10 transmits the answer screen data to the client 3 side. The client 3 side displays the answer screen as shown in FIG. 21 and confirms the substantial contents of the "dog named amber" related to the browsing request. Can be performed (S56).
The above-described layout design program is to generate a layout method adaptively by using item data attributes and the like associated with each item name as a message. It is not prepared. Also, when writing the substantive contents of each item in the layout data, similarly to the case of displaying the data list, each of [Item name and item data attribute etc.] and MDT 22 on the DPT 21 (FIG. 10) side. Since the substantive contents of each item name on the (FIG. 15) side correspond to each other in the data cell number, it is possible to execute the program with an extremely simple program description. Therefore, the program for generating the answer screen based on this browsing request is given as a single general-purpose program regardless of the category name, but automatically generates an adaptive display method for each different category name. It is. Although not shown, if there is a browse request specifying the title name “T-3360 telephone” in the data list for the category name [general telephone], the category name [general telephone] is changed to the category name [general telephone] in the same manner as described above. Such a display method is generated adaptively, and the client 3 side shown in FIG.
The answer screen shown in FIG.
Next, as a search that is frequently used in general DBS, a search accompanied by designation of a category name and designation of other conditions (hereinafter, referred to as "condition search") will be described. Here, assuming that the category name [dog] is specified,
The condition search procedure is shown in the flowchart of FIG. First, although not shown, in this embodiment, there is a screen on which a condition search can be specified as an option.
When the side requests a condition search on the same screen, the DBMS 10 activates a program for that (S61, S62). And D
The BMS 10 searches the CATG_KJ of the CLMT 19 (FIG. 3) based on the program and confirms the CATG_NO; “16” corresponding to [dog] (S63). Also, DPT21
The screen data for condition setting as shown in FIG. 24 is generated by the display method using the line-direction setting data related to the CATG_NO; “16” of (FIG. 10) as a message and transmitted to the client 3 (S64 ).
The client 3 receiving the screen can specify various conditions in the input fields of the screen shown in FIG. 24. Here, as shown in FIG. It is assumed that a condition of 4 years old or less and a condition of 15 kg or more and 35 kg or less for the item name [weight] are specified. Then, when an instruction is given by clicking a "search start" button, the search condition data is transmitted to the DBS1 side (S65).
On the DBS1 side receiving the search condition data, the DBMS 10 first extracts, as a population, data cells in the row direction corresponding to the above CATG_NO; "16" in the MDT 22 (FIG. 15) (S67). Also, the data cells (1) to (11) in the row direction of CATG_NO; "16" in the DPT 21 (FIG. 10)
, A data cell number corresponding to [age] and [weight], which are the item names according to the specified condition, is confirmed (S68). In this case, as apparent from FIG. 10, the data cell numbers are confirmed to be (2) and (3).
Next, the DBMS 10 stores the data cells in the column direction corresponding to the confirmed data cell numbers corresponding to the numbers (2) and (3) among the data cells in the row direction in the population extracted as described above. The search condition is applied to the stored data (S69). That is, the search condition is not applied to the data of the confirmed data cell number among the data cells in the row direction related to the category name [dog] (CATG_NO is "16") in MDT22 (FIG. 15). However, in this case, for each of the numbers Y and W in the column direction where CATG_NO is “16” and the data cell numbers are (2) and (3), 2 ≦ Y ≦ 4 and 15 ≦ W
The condition of ≦ 35 will be applied.
Then, the DBMS 10 extracts data in the row direction including data satisfying the above-mentioned search condition (S70),
Further, the screen data of the list by the condition search is generated by using the row direction setting data relating to the CATG_NO; “16” of the DPT 21 (FIG. 10) as a message (S71), and the row direction data extracted by the search is written and written. The subsequent screen data is transmitted to the client 3 (S72, S73). As a result, on the client 3 side, a list by the condition search as shown in FIG. 25 is displayed.
Are obtained by applying the above search conditions to the substantive contents of [item name]: [age], [weight]. In the list screen of FIG. 25, as in the case of the list of FIG.
Specific contents can be displayed by clicking each underlined individual title name or each separate window display portion.
4. Data change (update / delete) procedure On the client 3 side, the MDT 22 of DBS1 (FIG. 1)
There may be a case where you want to change the substantive contents registered in 5). For example, the specification of a registered product or the like changes, and it is necessary to rewrite or delete the substantial content related to a specific item name. In such a case, in the DBS1 of this embodiment, although not shown, in response to a request specifying a title name or a code number from the client 3, the registration, update, and registration of the data shown in FIGS. A delete screen is sent.
Therefore, when the above-mentioned need arises, the client 3 receives the screen, makes necessary corrections and deletions, and then executes the “Update this page” provided in the lower column. Click the button and the data after the change is D
Sent to BS1 side. Then, the DBMS 10 on the DBS1 side
Sets the registration data of the MDT 22 (FIG. 15) corresponding to the title as an update target, and overwrites the changed data to rewrite the registration data.
In this case, the DBMS 10 checks the correspondence between the data cells in the row direction of the category name including the title name in the DPT 21 and the data names in the row direction of the category name in the MDT 22 and the data cells in the row direction of the title name. After that, the change will be allowed. This DBS1
In, the rewriting of the registration data does not have any effect on other registration data on the system,
Of course, there is no need to change the program.
5. Procedure for changing items related to category When the function or attribute related to a real thing or event belonging to a registered category changes, the client 3 may request a change of the item, and the DBS1 responds to the request. There is a need to. In 4. above, MDT22 (Fig.
5) It could be executed arbitrarily on the client 3 side because it was only a change of the substantive contents stored in the data cells (1), (2), (3) ... In
This may change the DPT 21 (FIG. 10) and affect the function of the DBS 1. In principle, the management is performed by the management personal computer 15 on the DBS 1 side. That is, the data cell corresponding to each item name on the DPT 21 (FIG. 10) side and the data cell storing each substantive content on the MDT 22 (FIG. 15) side are associated with each other by the data cell number. Is lost, incorrect input / save / search / output is performed for the registration target of the category whose item has been changed.
By the way, as a mode of changing the item,
a. "Change item name", b. "Add item", and c.
"Item deletion" can be assumed. a. "Change of item name" does not affect the function of the system because it is merely a name change. When a plurality of clients 3 register data in one category name, MDT22 ( It is necessary to verify whether any of the substantive contents relating to the item name on the side of FIG. 15) causes a deviation, but if there is no problem, it can be accepted as it is. In addition, when the above-mentioned deviation occurs, it is often handled by the following b. “Addition of items”. If only a specific client 3 has registered data under one category name, there is no problem in allowing change of item names.
B. Regarding “addition of item”, refer to DPT2
1 (FIG. 10), the added item name and its item data attribute, etc. are set and registered for the corresponding category name, and the substantive contents are converted from the newly registered object using the DPT 21 (FIG. 10) setting data to the MDT 22. (FIG. 15).
In that case, the substantive contents registered before that will not exist for the added item, but for the search answer etc., if the area corresponding to the substantive content of the item name is blank displayed Is enough.
C. For “delete item”, refer to DPT2
The item name and its item data attribute in 1 (FIG. 10) are deleted, and the substantive contents of the corresponding column in MDT 22 (FIG. 15) are deleted. In that case, the specific client 3
Only has registered the data under one category name, and if it meets the request of the client 3, it may be accepted as it is, but if not, the other client
You have to get the consent of 3. However,
It is a problem for the client 3 whether or not the substantive contents are output in the search answer or the like, and not the deletion of the item on the DPT21 (FIG. 10) side but the substantive content on the MDT22 (FIG. 15) side , A substantially similar effect can be obtained for the request. The item name remains in the search answer or the like, but only the actual content of the item name is blank-displayed.
As described above, in the DBS 1 of this embodiment, it is possible to flexibly respond to a change in an item related to a category, and even if a change is made, data related to another category is not affected. Above all, having no programmatic restructuring is a major advantage.
The database system (DBS) of the present invention
Has the following effects by having the above configuration. According to the first aspect of the present invention, [substantive contents relating to each item name] to be registered in the second table is virtualized in the first table in a data format of [item name and item data attribute] for each category name, By associating the data of both tables with the sequential organization relationship of each data cell in the row direction, registration targets (events or things) belonging to all categories can be handled by two simple tables, and the DB
The method of each function of input, save, search, and output which is indispensable to S can be executed by one process control program. In this way, despite the fact that it covers all categories of events and things, it has only a very simplified table structure, and a general-purpose program is provided for each function regardless of the content of the data to be registered The feature that you only need to keep is the traditional RDB and OOD
B and ORDB are completely unpredictable.
To achieve dramatic cost reduction in the construction of Further, it is possible to flexibly respond to changes in data and items, it is not necessary to change programs that require enormous time and effort in the conventional DBS, and it is possible to greatly reduce system operation and maintenance costs. According to a second aspect of the present invention, based on the first aspect of the present invention, a guidance function is added to facilitate a data registration procedure, and a more practical DBS is constructed. Also, at the time of data registration, a guidance screen (second registration screen) is rationally and adaptively generated using the [item name and item data attribute] virtually configured in the first table, Realize excellent functions as a user interface. The invention of claim 3 clarifies that a data type is optimal as a definition item of an item data attribute, and at least if the data type is defined, a system operation can be guaranteed. According to a fourth aspect of the present invention, by defining a data size together with the data type, it is possible to prevent a large unused area from being formed in a data cell of the second table. According to the fifth aspect of the invention, by further providing a unit and a range as the definition items of the item data attribute, it is possible to appropriately express attributes and functions of each item of any object existing in the natural world. The invention according to claim 6 makes it possible to basically and generally cover a method of expressing substantive contents relating to each item name. The invention according to claim 7 enables a wide variety of data existing outside the system to be fetched and registered, thereby greatly expanding the use form of the database system. The invention according to claim 8 prevents the data amount stored in the data cell of the second table from being extremely unbalanced, and facilitates the management of the registered data. According to the ninth aspect of the present invention, the display order of the substantive contents on the search answer screen or the like can be arbitrarily set in advance, and a screen adapted for each category can be displayed.
