数据库集成在智能小区管理系统中的应用

Application of Heterogeneous Database Integration In the Design of Management System of Intelligent Building

针对智能化小区管理系统项目中关于异构数据库集成问题,给出了一个基于XML和Java的异构数据库集成解决方案,即在原有基于B/S的三层结构中间添加一个中间1层,提供调用者和异构数据库之间的无缝连接和透明访问。中间层由元数据、分解组合器和查询器三大部分组成。

In view of the problem about heterogeneous database integration in management system project of intelligent building, a scheme is proposed based on XML and Java, namely a mid-layer is added to the former three-layer structure based on B/S to provide seamless connection and sheer visit between users and heterogeneous database. The mid-layer consists of three parts, including metadata, disassembling-assembling implements and consulting implements.
