Identifying data within a data store satisfying a request. A quantity of the identified data is greater than a threshold. The identified data is analyzed to produce an initial result set with a reduced data quantity including information summarizing the identified data. The analyzing includes visualizing the information summarizing the identified data as one or more graphical displays rendered within a user interface and selectively filtering the identified data based upon a selection of filter factors associated with the identified data to generate an initial result set having a smaller size in relation to the identified data set. Each of one or more succeeding result sets are generated from a corresponding prior result set until a succeeding result set includes a quantity of data satisfying the threshold. The generating of each succeeding result set includes filtering the corresponding prior result set and information summarizing the filtered result set.

Reducing a large amount of data to a size available for interactive analysis

A request for data is processed by identifying data within a data store satisfying the request, where an amount of the identified data exceeds a threshold, analyzing the identified data to produce an initial result set with a reduced amount of data including information summarizing the identified data, and generating one or more succeeding result sets each from a corresponding prior result set until a succeeding result set includes an amount of data satisfying the threshold. Each succeeding result set includes a reduced amount of data relative to the corresponding prior result set, and generating each succeeding result set includes filtering the corresponding prior result set and generating the succeeding result set including information summarizing the filtered result set.

A system and computer program product for developing software in which the software comprises a plurality of programs. A change to a program is received. A data structure checking procedure may then be invoked. The changed program is parsed for a reference to a data structure. Other instances of the data structure are located in other programs within the software. The referenced data structure is compared to the located other instances of the data structure. A predefined action (such as notifying a programmer or correcting the inconsistencies) is performed in response to any detected differences between the referenced data structure and the located other instances of the data structure. These steps are repeated for all data structures within the changed program.

Maintaining consistency amongst data structures that are referenced within different programs
