Abstract

This facility allows the user to define criteria that will be used to select a subset of information from stored information files. The subset is narrowed or expanded by increasing or decreasing the number of criteria defined. When users of an application wish to review a subset of information kept as file records, they usually determine which subset of records is required based on the values of the fields that comprise the file records. If the resulting selection is large, the user may want to refine the selection criteria so that the set found is smaller. On the other hand, if few or no records are found, the selection might have to be broadened to find a larger set of information. Respecifying the selection criteria for each selection can be tedious and time consuming.

Subset-Selection Mechanism

This facility allows the user to define criteria that will be used to select a subset of information from stored information files.

The subset is narrowed or expanded by increasing or decreasing the number of criteria defined. When users of an application wish to review a subset of information kept as file records, they usually determine which subset of records is required based on the values of the fields that comprise the file records. If the resulting selection is large, the user may want to refine the selection criteria so that the set found is smaller. On the other hand, if few or no records are found, the selection might have to be broadened to find a larger set of information. Respecifying the selection criteria for each selection can be tedious and time consuming. IBM Professional Work Manager (PWM) uses a mechanism that simplifies the user's job of selecting a subset of tasks. It can also display a count of the number of records available as each selection criterion reduces the number of tasks available. This can help the user manage the size of the list of tasks from which he or she will work. The subset selection mechanism associates codes with field values and builds indices to data records. This happens at the time the records are created or changed. Values and records with the same code for the values of a particular field become part of the same set. PWM uses these associated codes as an indexing mechanism for searching a...
