Declaration programming language extension for procedural programming languages
InactiveUS6145120AImprove performanceGuaranteed independence and securitySoftware engineeringKnowledge representationPerformance enhancementProcedural programming
Complex declarative programming capabilities are provided through an underlying procedural programming code by functionally providing the selection algorithm of known declarative processing arrangements in explicit conditional constructs in procedural language embodying a rule or rule function statement. This approach simultaneously provides declarative processes easily and simply in a relatively few lines of procedural code while isolating the processing to the rules and objects, themselves, thereby providing reduction in hardware overhead requirements and performance enhancements which will be more fully discussed below. Further, by providing for updating of attributes and relationships of objects together with time tags associated with the update and removal of objects from list for evaluation, imprecise evaluation and heuristic reasoning may be readily developed while providing further performance enhancements to known Lazy Evaluation procedures.
