ACTIVE RULES RANGE ESTIMATION ON REGULAR EXPRESSIONS
The purpose of the research is to describe an range estimation method of active database rules with string parameters. Demonstrated, how rules range estimation can be used in static analysis, when potential rules interactions scenario is determined and parameters of events, which processing cause to conflict situations, is identified. Possibility of use of regular expressions to set the active rule is justified and active rules format, which based on regular expressions, is described. Connection scheme of finite state machines, which synthesized on regular expressions, is developed. A possible operation on these finite state machines, needed in static analysis, is highlighted. Examples of applications of active rules in describes format are given.
