触发器是一种特殊的存储过程,它的主要作用是实现由主键和外键所不能保证的、复杂的参照完整性和数据的一致性,房产管理信息系统是企业信息化中的一个重要部分。随着计算机技术和网络技术的不断发展,如何设计并实现出高效的房产管理信息系统成为当务之急,而触发器正是有效实现数据操作的一种手段。首先介绍房产管理系统的系统设计和数据库设计,接着介绍多个触发器的设计与实现;最后给出这种方法的实现效果。
Trigger is a special storage process, its main role is to achieve by the primary key and foreign key can not be guaranteed, the complexity of the referential integrity and data consistency, real estate management information system is an important part of enterprise information . With the continuous development of computer technology and network technology, how to design and implement an efficient real estate management information system has become a top priority, and the flip-flop is an effective means of data manipulation. First introduced the real estate management system design and database design, and then introduces the design and implementation of multiple triggers; Finally, the effect of this method is given.
