FR 3102585 A1 20210430 FR 1912117 A 20191029 Embodiments of the present invention provide a method, system and computer program product for single view presentation of multiple query. In an embodiment of the invention, a method for single view presentation of multiple query includes directing a query against a database along a selected dimension of multiple different elements. In response, a primary result set is received. The result set is then organized into a tabular view of cells according to the selected dimension and values for the selected dimension. Thereafter, a set of nested queries may be directed for each of the elements in the selected dimension against the result set utilizing a different dimension. In response to each directed set of nested queries, a corresponding result set is thus received. Finally, each corresponding result set is inserted into a cell associated with a common one of the elements. Figure accompagnant l’abrégé: Figure 3 SINGLE VIEW PRESENTATION OF MULTIPLE QUERIES IN A DATA VISUALIZATION APPLICATION The present invention relates to the field of data visualization and more particularly to the visualization of complex nested database queries. Data visualization refers to the graphical expression of one or more relationships between data in a collection of data. A most typical form of a collection of data is a database in which data is stored, and in many cases, managed by a separate application such as a database management system. The conventional database management system provides a programmatic user interface through which database queries may be received from other computing processes local or remote, and from which results to those queries may be provided to the querying computing processes. A common form of a query selects a set of records in a database for consideration, a dimension, e.g. a primary field of interest in the set of records of the database, and a measure, e.g. a value for a corresponding secondary field of interest in a result set of records. Filtering and limiting criteria also may be specified in addition to a sorting directive as to how to sort a presentation of the result set of records, and aggregate functions operating upon the returned measures amongst the set of records returned in response to the query. Notably, different visualizations of the measure relative to the dimension may be provided including the venerable pie chart, line graph and bar chart visualizations. As in the natural world, in most instances, a single query is not enough to answer a real-world question corresponding to the query. Rather, multiple queries are required. In many instances, each successive query amongst the multiple queries depends upon a result set of a prior query--thus the notion of a nest query in which a successive query or even successive queries, depend upon a result set of a prior query. Visualizing a single query in a user interface typically is of no consequence, but for visualizing multiple queries, the opposite is true. Indeed, visualizing multiple queries in a single user interface view requires significant optimization of the user interface so that not only does each visualization for each query enjoy adequate screen space within the user interface, but also that the dependency relationship of each visualization is apparent. So much has proven ineffective to date. Thus, the end user is left in a state of confusion, unable to correlate the visualization of one query with one or more of its counterparts present. The result is a failure to holistically interpret the result sets of the various queries. Embodiments of the present invention address deficiencies of the art in respect to database query result set visualization of multiple database queries, and provide a novel and non-obvious method, system and computer program product for single view presentation of multiple query. In an embodiment of the invention, a method for single view presentation of multiple query includes directing a query against a database along a selected dimension of multiple different elements. In response, a primary result set is received. The result set is then organized into a tabular view of cells according to the selected dimension and values for the selected dimension. Thereafter, a set of nested queries may be directed for each of the elements in the selected dimension against the result set utilizing a different dimension. In a response to each directed set of nested queries, a corresponding result set is thus received. Finally, each corresponding result set is inserted into a cell associated with a common one of the elements. In one aspect of the embodiment, a graph may be generated for each corresponding result set. Subsequently, the graph for each corresponding result set may be inserted into a cell associated with a common one of the elements. In another aspect of the embodiment, a different set of nested queries may be directed for each of the elements in the selected dimension against the result set utilizing an additional dimension. In response to each directed different set of nested queries, a different corresponding result set is then received and a different graph generated for each corresponding different result set. Finally, the generated different graph for each corresponding different result set may be inserted into a cell associated with a common one of the elements. Other aspects of the embodiment include limiting each corresponding result set to a maximum number of values. Yet further aspects of the embodiment include directing the set of nested queries for each of the elements in the selected dimension against the result set utilizing a different dimension in response to a selection of a dimensionalization menu entry in a pop-up menu for the tabular view. In this regard, the dimensionalization menu entry upon selection may present a dialog box providing for a selection of a sort order of each corresponding result set. In another embodiment of the invention, a data visualization data processing system is configured for single view presentation of multiple query. The system includes a host computing system with one or more computers, each with memory and at least one processor. The system also includes a database coupled to the host computing system and storing data therein. The system yet further includes a database visualization application executing in the memory of the host computing system and adapted to issue queries against the database and receive result sets in response to the queries. Finally, the system includes a single view dimensionalization module coupled to the application. The module includes computer program instructions that when executing in the memory of the host computing system directs the database visualization application to query the database along a selected dimension of multiple different elements and receiving in response, a primary result set, organizes the result set into a tabular view of cells according to the selected dimension and values for the selected dimension, directs the database visualization application to perform a set of nested queries for each of the elements in the selected dimension against the result set utilizing a different dimension and receives in response to each directed set of nested queries, a corresponding result set. Finally, the program instructions insert each corresponding result set into a cell associated with a common one of the elements. Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed. The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein: Figure 1A, taken together with Figure 1B, is a pictorial illustration of a process for single view presentation of multiple query in a data visualization application; Figure 1B, taken together with Figure 1A, is a pictorial illustration of a process for single view presentation of multiple query in a data visualization application; Figure 2 is a schematic illustration of a data visualization computer data processing system adapted for single view presentation of multiple query; and, Figure 3 is a flow chart illustrating a process for single view presentation of multiple query in a data visualization application. Embodiments of the invention provide for single view presentation of multiple queries in a data visualization application. In accordance with an embodiment of the invention, a database query is formulated along a selected dimension of multiple different elements of data in a database and issued to a database management system of the database. In response, a primary result set for the query is received and organized into a tabular view of cells according to the selected dimension and those values for the selected dimension present in the result set. Thereafter, a set of nested queries may be directed for each of the elements in the selected dimension against the result set utilizing a different dimension of the multiple elements of data in the database. Consequently, a corresponding result set is received from the database management system for each one of the directed sets of nested queries. Each corresponding result set then may be inserted into a cell associated with a common one of the elements of data in the database and preferably, a graph is generated for each corresponding result set and inserted into a cell associated with a common one of the elements in lieu of the insertion of the corresponding result set. In this way, a single tabular view of the multiple different result sets from multiple nested queries based upon the result set of prior queries may be arranged for viewing in one place presenting a large amount of data without the need for separate graphical views for each of the queries and while visually associating each nested result with a source query from the result had been derived. In further illustration, Figure 1A pictorially shows a process for single view presentation of multiple query in a data visualization application. As shown in Figure 1A, an instance 100A of a database exploration user interface is presented in connection with the visualization of data in a selected database. The instance 100A permits user interaction with a visualization configuration portion 110 of the instance 100A through which a dimension and a particular one of a set of measures 120 may be specified along with aggregation, sorting and limiting functions in formulating and directing execution of a query to the selected database. A result set for the executed query is then presented as a visualization 140 in a tabular view. The result set may be subjected to one or more filters 130 as shown herein. Upon selection of a dimensionalization menu entry in the visualization configuration portion of the instance 110, a set of nested sub-queries for the result set may be specified including the specification of an additional dimension as can be seen. As well, one or more filters 150 further may be specified. In response to the dimensionalization directive, a sub-query consistent with the selected additional dimension is generated for each result set of the previously executed query presented as the visualization 140 in the tabular view. The sub-results may be subjected to additional aggregation such as a top N results, a sum, average or other such aggregation. Sub-results are received for each sub-query and optionally, a graphical representation of the sub-results is generated. Then, each of the graphical representations are included in an expanded form of the visualization 140 in a new instance 100B of the database exploration user interface, and in correspondence to a sub-result to which a sub-query for the graphical representation had been directed. As it will be apparent, and as shown in Figure 1B in respect to an instance 100C of the database exploration user interface, further nested sub-queries may be initiated by selecting yet additional dimensions when directing a dimensionalization of the result set of the original query, or any sub-queries thereafter. As well, each sub-query conducted as part of a dimensionalization may be filtered differently so as to produce different result sets which may be included in a different column of the tabular view of the instance 100B. Even further, graph for each sub-query conducted as part of a dimensionalization may be a result of a pivoted form of a prior query, but presented in a same row as a graph of the prior query. In this way, multiple different query views for multiple different measures of one or even two dimensions may be visualized in a single view with the relationship therebetween evident from the placement of each visualization in association with each other visualization relating to a common element of a result set of an initial query. The process shown in Figures 1A and 1B may be implemented within a data visualization computer data processing system. In yet further illustration, Figure 2 schematically shows a data visualization computer data processing system adapted for single view presentation of multiple query. The system includes a host computing platform 210 of one or more computers, each with memory and at least one processor. The host computing platform 210 is coupled over computer communications network 240 to a database 220 managed by database management system executing in a separate computer 230. A data visualization application 250 executes in the memory of the host computing platform 210 and provides data visualization functionality to different client computers 260 over the computer communications network 240 by way of respectively different data visualization clients 270. Of note, a single view module 300 is coupled to the data visualization application 250. The single view module 300 includes computer program instructions that when executing in the memory of the host computing platform 210 are enabled to receive an initial query specifying a dimension and measure for a specified table in the database 220, including by way of example, an aggregation function such as a sum, average or other aggregation. In consequence, the single view module 300 is enabled to direct the data visualization application 250 to transmit the query to the database management system 230 and to receive, in turn, an initial result set of records which may then be organized in a tabular view in which each row of the tabular view reflects a single record in the initial result set, and in which the rows are sorted according to a specified sort order of the query, and further in which the rows are limited to a specified number of records as set forth in the query. The program instructions additionally are enabled to respond to a selection of a dimensionalization directive by identifying a different dimension within the directive and formulating a sub-query based upon the different dimension. As well, the program instructions execute the sub-query against each measure of the initial result set so as to produce a secondary result set for each measure--namely each record of the tabular view. Thereafter, a graph may be generated for each secondary result set for each measure in accordance with a graph type selection specified as part of the dimensionalization directive. Finally, the program code is enabled to augment the tabular view with a new column and to insert in each row of the new column, one of the generated graphs that corresponds to one of the measures of the initial result set for which the secondary result set reflected by the generated graph had been procured in consequence of the sub-query. In even yet further illustration of the operation of the single view presentation module, Figure 3 is a flow chart illustrating a process for single view presentation of multiple query in a data visualization application. Beginning in block 310, an initial query is received specifying a table, dimension and measure. In block 320, optionally, filter criteria, a record limit and/or a sorting criteria is determined in the initial query. In block 330, the initial query is then executed against a database specified in the initial query so that a result set is returned. In block 340, the result set is visualized in a tabular view of a set of records associating each record of the specified dimension with a corresponding measured value. In block 350, a dimensionalization directive is received in a user interface to the data visualization application. In response, a dimension is determined for the directive and in block 370, a nested query is formed for each result in the initial result set. A secondary result set is then received in block 380 for each result of the initial result set. In block 390 a graph is generated for each secondary result set. Then, in block 400 each generated graph is inserted into a row of a cell of a new column of the tabular view corresponding to a result of the result set of the initial query common to the secondary result set of the secondary query.
