       [0002] The present invention relates to an information processing system and a method for communications between application systems.  
       [0003] 2. Description of Related Art  
       [0004] In related art, information processing with computer systems is described and specified with C or COBOL language. However, in the related art, a programmer needs to modify the program in case an input file or a procedure is changed. In addition, the modification of related programs is required.  
       [0005] On the other hand, suppose information processing occurs through the network such as WAN (Wide Area Network) or the Internet. FIG. 1 shows the communication method between application programs in the related art. In FIG. 1, a computer system  405 , which executes an application A, and a computer system  407 , which executes an application B, are connected with network  409 , and they can communicate with each other by using the network  409 . In this case, the EDI (Electric Data Interchange), like CALS (Commerce At Light Speed), JCA (Japanese Chain-store Association procedure), or the distributed object technology, like DCOM, CORBA can be used.  
       [0006] In the related art, information transmissions between application systems are often used among companies with different servers, languages, and protocols. Accordingly, proprietary communications means is needed for different communication partners, which results in the lack of flexibility. Thus, it is difficult to incorporate the communications means into an application program.  
       SUMMARY OF THE INVENTION  
       [0007] An object of the present invention is to provide an information processing system and method for communications between application systems that is capable of modifying the procedure easily, and furthermore, without preparing a program.  
       [0008] The present inventor has found out that the programming time can be reduced by employing a software program as a component and combining with them using the class in the object-oriented technology.  
       [0009] According to this invention, an information processing system is provided, which comprises a batch control class for passing a beginning message, and scheduling after receiving a completion message; an input class for inputting data based on conditions when receiving the beginning message from the batch control class and passing the completion message to the batch control class upon completion of input processing; a conversion class for converting the input data based on conditions upon receiving the beginning message from the batch control class, and passing the completion message to the batch control class upon completion of conversion processing; and an output class for outputting data based on conditions upon receiving the beginning message from the batch control class.  
       [0010] Another object of the present invention is to provide a flexible way of communications between application systems in above cases.  
       [0011] The inventor considered how communications are realized more easily. So the inventor found out that the communications between application systems could be realized by using the Internet mail, as a means for transmitting data and process. And, since the account of the Internet mail is used as an application interface, communications between application systems can be realized with through network topology. Accordingly, method for communications between application systems can be realized with flexibly even in the various companies, servers, languages, and protocols.  
       [0012] According to this invention, an information processing system is provided, which comprises a mail interface unit for receiving a mail as a mail format for an Internet; a receiving unit for changing the mail into receiving data which is executable for an application unit; and the application unit for executing an application using the receiving data.

     DETAILED DESCRIPTION OF THE EMBODIMENTS  
     [0069] Various embodiments of the present invention will be described with reference to the accompanying drawings. It is to be noted that the same or similar reference numerals are applied to the same or similar parts and elements throughout the drawings, and the description of the same or similar parts and elements will be omitted or simplified.  
     [0070] Object Oriented Model  
     [0071] Each class subjected to object oriented data model has elements including member and method. The class has at least one member. Each class determines its behavior with at least one parameter. The parameter is often used as an instance (instance value), the parameter is incorporated into a program to determine the behavior of the program. Accordingly, the term “parameter” includes an instance (instance value) to determine behavior of a program. The term “methods” is a procedure executed by each class. The term “passing” includes sending and receiving messages between the classes, and term “passing” is defined by a method. The message includes request for operations and confirmation regarding operation result.  
     [0072] Information Processing System  
     [0073] To provide the information processing system of the present embodiment, software that realizes the processing as described below is written, and a computer system is used for enabling implementation of the processing. The term “computer system” may include a main frame computer, workstation, PC, or the like. The hardware configuration of the computer system used in the present embodiment includes a CPU that performs various operations, an input device, such as a keyboard, mouse, light-pen, or a flexible disk device, an output device, such as a display or a printer, or other devices. The CPU includes an operating unit that processes commands associated with the processing of each scheduling unit as explained later, and a main storage unit that stores the commands generated during the processing. The operating unit sequentially reads commands stored in the main memory unit, or external storage device, and executes the commands so as to perform processing for production and inventory control.  
     [0074]FIG. 2 is a block diagram showing information processing system according to an embodiment of the present invention. The system according to this embodiment comprises a batch control class  11  for passing a beginning message, and scheduling the next class according to a completion message from a class, an input class  13  for inputting data based on at least one parameter in case receiving a beginning message from the batch control class  11 , a conversion class  15  for converting the input data based on at least one parameter in case receiving a beginning message from the batch control class  11 , and outputting a completion message to the batch control class  11  in case of completion of conversion processing, and an output class  17  for outputting data based on at least one parameter in case receiving beginning message from the batch control class  11 .  
     [0075] The batch control class  11  controls the input class  13 , conversion class  15 , and output class  17 . The control of the batch class  11  sends a beginning message to each class based on at least one parameter (typically, instance value), receives a completion message (typically event) from each class, and schedules the next class. The schedule of the class is carried out in the order of input class  13 , the conversion class  15 , and the output class  17 . Hence, the batch control class  11  sends a beginning message to the input class  13 . Next, the batch control class  11  sends a beginning message to the conversion class  15  after receiving the completion message from the input class  13 . And the batch control class  11  sends a beginning message to the output class  17  after receiving completion message from the conversion class  17 .  
     [0076] The parameters of scheduling are determined when generating the batch program which describes processing. The batch program is generated and program source code stored by a class library is prepared, and the parameters are incorporated into the program source code. Also, the parameters of scheduling are stored at the batch information instance of unit  23 , the batch control class can refer as needed to the batch information instance of unit  23 .  
     [0077] The input class  13  is a class which receives a beginning message from the batch control class  11 , then receives data from the input data stored in unit  25  based on at least one parameter indicating an input procedure. And the input class  13  prepares input file and outputs completion message to the batch control class  11  in case of completion of the input procedure. The input procedure includes preparing an input process index file, or a reference index file, checking the format of input file, and matching or sorting of the files.  
     [0078] The conversion class  15  is a class which receives a beginning message from the batch control class  11 , then converts the input data based on at least one parameter indicating a conversion procedure. And the conversion class  15  outputs a completion message to the batch control class  11  in case of completion of the conversion procedure.  
     [0079] The conversion class  15  is activated when receiving the beginning message. Next, the class  15  converts data based on parameters. The process results or status including such as interruption, abortion, normally completion are sent to the job control class  11 . Next, the class  15  output a completion message to batch control class  11 .  
     [0080] Here, the principal methods include conversion methods, check methods, and service methods. Each method is executed the data once or several times. After processing, the data outputs as a conversion-work. Here, the term “conversion works” means temporary file for storing the processing data temporally.  
     [0081] The output class  17  is a class which outputs the conversion-work processed by the conversion class  15  to an output unit at a output form based on at least one parameter. The output class  17  receives a beginning message from the batch control class  11 , then inputs the conversion-work based on at least one parameter indicating an output procedure. And the output class  17  outputs the output data and completion message to the batch control class  11  in case of completion of the output procedure. The output form includes text file, CSV file, import form file, DB file, certification output. The output data are stored by an output data storing unit  27 , or are printed.  
     [0082] A job control class  19  receives status message outputted by the conversion class  15 , then the class  19  outputs the status message to the log storing unit  29 , or the class  19  outputs the status, such as a number of processing, to the job management system  21 .  
     [0083] A job management class  21  is a class which receives the status outputted by the job control class  19  to manage jobs.  
     [0084]FIG. 3 shows an example of a class diagram according to an embodiment. Here, schedule data of the batch control class define a procedure of each class. The procedures are determined by at least one parameter.  
     [0085] The methods of the input class include a sort input method for inputting a file with sorting, a merge input method for inputting files with merging, a matching input method for inputting files with matching, a DB input method for inputting from a database, and a file input method for inputting from a file.  
     [0086] The methods of the conversion class include a sort method for sorting data in a file, a format method for converting a format of data in a file, a replace method for replacing data in a file, an expansion method for expanding data in a file, a matching method for matching data in files, a summary method for summarize data in a file, a consistency check method for checking whether data in a file have consistency or not, and an exceptional process method. The methods may outputs processed data as a conversion-work.  
     [0087] The methods of the output class include a text method for outputting the file as a text file, a CSV file output method for outputting the file as a CSV file, an import form file output method for outputting the file as an import form file, a mail method for sending the file to at least one e-mail account, a list output method for outputting the file as a list form, a DB output method for outputting the file to a database, and a certification output method for outputting the file to outputting the file as a certification form.  
     [0088]FIG. 4 is a view illustrating a conversion process of a conversion class. First, the format method performs format conversion of data in a file. For example, data in a file described in form “97/12/01” is converted to “December 1, 1997”. Another example, data in a file described in form “1000” is converted to “¥1,000-”.  
     [0089] Next, the replace method performs data replacement in a file. For example, data in a file described in form “100EA”is replaced to “@100”.  
     [0090] And, the expansion method performs data expanding in a file. For example, data in a file divided by the slash (/) like “product name/part name” is expanded to each product name and part name, like “AAA” “BBB”. Another example, a matrix data in a file like “A[10]” will be expanded to each element of the matrix like “A(1), A(2), . . . , A(10)”.  
     [0091] Information Processing System for Preparing Programs  
     [0092]FIG. 5 is a view illustrating a conversion process of a conversion class. First, a class for processing is copied from a class library  31 . Then, a definition unit  33  of parameter defines the instance value of the copied class using wizard, then the program source code  35  incorporating the instance value is generated. This will be mentioned later. The compile processing is carried out by the Program generation unit  37 , and, as for this program source code  35 , the executable file  39  is generated. Information processing according to the embodiment is realized by performing this executable file  39 .
