基于CORBA的数据库中间件的研究与实现

Research and implementation of CORBA based on database middleware

研究基于四川联通传输网综合网管系统,提出一种可用于管理分布式数据库连接的数据库中间件。中间件位于网管系统客户端和数据库服务器之间,统一处理每个客户端发出的数据库访问请求;提供统一的分布式环境下数据库访问接口API,包括创建连接、查询数据、提交事务等,屏蔽数据库的异构性;能够有效地管理数据库连接等资源,提供稳定的数据库服务。在原有网管系统中引入本中间件以后,系统不再需要通过JDBC提供的API来访问数据库。

The research was based on Integrated Network Management System of Sichuan Unicorn.It was raisd a database middleware which could be used to manage distribute connections. The middleware was located between client and DBMS, and provided uniform database accessing API under the distribute environment. The middleware could manage distribute connections effectively and provide steady database service. Network Management System could use this middleware instead of JDBC.
