| 摘 要： | 触发器是当前商用DBMS用于完整性实施和主动控制的一个主要机制。为了满足许多应用系统对数据库系统的主动性需求，提出了一种基于触发器机制的主动数据库的新模型，并且在此模型基础之上，运用了一种简单的、易于实现的方法来建立基于触发器机制的主动数据库。

| Abstract: | Trigger is an important mechanism of integrity enforcement and active control for commercial DBMS. In order to satisfy the active needs of many application systems for the database systems, a new model of an active database based on triggers was presented. And on the basis of this new model, a simple method that can be realized easily was applied to set up an active database based on triggers. |
