基于J2EE的数据库连接服务

讨论了数据库连接服务体系结构,并详细地阐述了既支持连接池,又支持分布式交易的连接管理模块的规范设计以及功能实现.该设计不仅使应用代码具有较好的可移植性,而且能够在很大程度上改善应用服务器的整体性能,可为商务应用高效、透明地访问各种关系数据库管理系统提供一种更优的选择方案,特别适合分布式计算环境下的多用户并发访问。

Database Connection Service Based on J2EE

In this paper the architecture of database connection service in application server is discussed.The standard design and function implementation of connection manager module which supports both connection pool and distributed transaction is illuminated in detail.The design not only makes applications more portable, but also greatly improves the performance of application server. A good choice is provided for efficient and transparent accessing all kinds of relation database management system. It is very fit for concurrent multiuser access in distributed computing environment.
