An improved method for handling database queries including functional expressions against columns having enumerated storage is described. Upon receipt of a query including a predicate having at least one functional expression referencing at least one database column containing offsets to values in enumerated storage, a look-up table is created for storing results of evaluation of the predicate against the values in enumerated storage. Each functional expression of the predicate is evaluated against the values in enumerated storage and the results of evaluation are stored in the look-up table. Results stored in the look-up table may then be accessed through use of the offsets to values in enumerated storage. The method may also be utilized for projecting expressions against database columns having enumerated storage.

A system for dynamically integrating changes in rules governing business operations into a rule-implementing application program includes a dynamic business logic rule integrator (“DBLRI”) that provides rules to the application software as executable routines. The DBLRI presents to a user one or more GUIs through which the user writes functional-language expressions for the rules. The GUIs provide menus of associated functions, operators and parameters that are available for use. The set of parameters associated with a given GUI is dynamically updated, to correspond to changes in the underlying business logic rules. The user writes and / or edits the expressions by selectively combining the available functions, operators and parameters. The DBLRI evaluates the functional expressions and produces associated executable parse trees or DLLs, which the application software then calls at appropriate times. The DBLRI operates also with a dynamically configurable database that provides parameters required for the rules as the rules are updated, added and / or revised.
