触发器在实验管理系统中的设计与应用

Application of Trigger Mechanism in Experiment Information Network Management System

在设计开发实验管理系统过程中,我们设计并应用了数据库管理系统提供的触发器机制,使用DML类触发器实现了级联更新以及保证数据完整性的功能,最后总结了目前触发器机制的几个潜在应用。

In data managing system,when import data of new experimental users or export the data of the users whose experimental scores have been reported,we design and use the triggers provided by the data managing system,i. e. ,use DML triggers to realize cascading renew and to guarantee the database integrity.
