Research On Dynamic And Monitoring Pre-Warning For Social Security Audit Based On Active Database Technology

In recent years, the requirements of people on traditional database with active processing become higher and higher, and database system can automatic processing according to pre-treatment strategy. Therefore, the field of active database technology is also more extensive, In the pre-warning system for social security auditing, it proposed a dynamic, proactive pre-warning mode, the face of changes in the pre-warning mode, this thesis using active database technology to the existing system, which solve the problem about lack of dynamic and proactive in the existing pre-warning system.First of all, based on the results of active database research at home and abroad, this thesis combined with Requirements on dynamic and proactive, which presents an active monitoring model based on ECA rule, and gives an detailed description on the function of each Module and their relationships. Secondly, this thesis give an research on the construction method of rule database, including definitions of rule, storage structure of rule database, the trigger mechanism of rules and the management of rule database, for the problem of active rule's processing mechanism in active monitoring model, this thesis gives the type of monitoring event and monitoring mechanism of the event, and according to the design for storage structure of rule database, gives a detailed description of active rule processing and algorithm of rule processing.Finally, according to the requirements of Pre-warning system for social security auditing, this thesis gives system design based on the results, and gives the verification experimental to the design, the dynamic monitoring pre-warning system which using active database technology has a high dynamic and proactive.
