Active Database Technology And Applications

Active Database is the integration of database and artificial intelligence; technology, which enable database to be able to automatically react to events. An active database supports Event-Condition-Action (EGA) rules. Occurrence of various types of events (e.g., database transitions, time events, and external signals) triggers the evaluation of a condition and if the condition evaluates to true, the action is carried out. It satisfy the people's requirements of active services. In this paper, we introduce the concept about Active Database and present a general model of Active Database and give the technique of implementation. We also describle the procedure of developing the Market Management System of Beijing Industrial and Commercial Administration Agency. And we provide a detailed description of developing the system providing active prediction ability with Active Database technology.
