Research And Implementation Of XML Database Active Rule

The paper indicated the limitation of traditional XML database application model by analysis the application and research of current XML database at first. Then, it discussed the active rule in database and researched how to extend current database to XML database. At last, presented the realization of the XML active database using concretely application model.This followed are the paper mainly having finished work:1) By Analysis the construction feature of XML and the knowledge model of XML database, studied the possibility of active rule using in XML database and constructed the active rule model based XML construction feature.2) By extending active database and applying XML executed model, studied the problem of how to combine XML database and active rule effective from theoretics, constructed a frame model based XML active database. Then, analyzed how to apply active rule in XML database by using the XML Schema model criterion.3) It extended the active rule from relational structure to structural data, studied application of composite event. Presented active model to dealing substructure event. Resolved how to construct active rule model by using XML Schema syntax and how to design trigger to realize active rule retrieve by using XQuery language.4) By applying the frame model of XML active database, presented a series of strategy of model, resolved the problem of that traditional information web system can't be in time and intelligent, discussed it in practically field.
