在主动和实时数据库理论的基础上 ,提出了一种支持现代应用的主动实时数据库系统 (ARTDBS)的触发器机制 。
On the basis of the theory on active and real_time database,this paper suggests an active real_time database system ARTDBS supporting advanced application,which perfectly integrates traditional DBMS capabilities,active capabilities,and real_time constraint mechanism.The active mechanism in ARTDBS is the trigger mechanism.Effective work of the triggers depending on design of the system execution model isanalyzed in detail,and an execution model of the trigger is developed based on WINDOWS NT environment.
