嵌入式关系数据库管理系统中主动模块的设计与实现

Design and Realization of Active Module in Embedded Relation Database Manage System

称动计算环境与传统的计算环境有很大的不同,因此传统的主动数据库在移动设备上的应用受限。提出一种嵌入式关系数据库管理系统中主动模块的设计与实现,对主动规则进行了扩充,同时将主动模块放置于管理系统的内核中实现,不仅可以定义与处理复杂的主动规则,而且提高了数据库管理系统的效率。

There are great difference between mobile computer environment and tradition computer environ- ment. The difference limited the applied of tradition active database in mobile device. A realization method of active module in embedded relation database manage system is provided. This method expandsd the active rules, and re- alizes the active module inside the kernel. Then the method not only can define and deal with complex active rules, but also improve the efficiency of database manage system.
