多层应用软件体系结构中数据库中间件原型的构造

Construction of Database Middleware in Multi-tier Application Architecture

针对目前 3层应用软件体系结构中数据库中间件存在的问题 ,提出了一种数据库中间件原型的构造方法。通过对数据库连接和访问机制的管理 ,改善了多用户访问同一数据库时的网络性能 ,并可透明访问多种数据库 ,提高了多层应用软件体系结构中远程数据库访问的可靠性 ,具有良好的可重用性。

Considering the present problem existing in the three tier application architecture,an approach of constructing database middleware is proposed in this paper.Through the management of database connection and data access,it can make full use of results of the same operation,improve the network performance when the same database is accessed by multi user,access various databases transparently,increase the reliability of access to remote database in multi tier application architecture,and thus have good reusability.
