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.
