在J2EE平台下进行多层分布式数据库系统开发的研究

Research to Develop Multi-tier Distributed Database System with J2EE

J2EE是SUN公司提出的在分布式环境中的一种体系结构,EJB是基于J2EE(Java2平台企业版)开发基于Web企业应用程序的基础,EJB体系结构是生成业务应用程序的主要分布式组件模型。本文介绍了J2EE和EJB基本概念和特点,并列举了在J2EE平台下运用EJB技术开发多层分布式数据库系统的开发示例。

J2EE is a architecture of distributed environment which was put forward by SUN Enterprise. EJB is the foundation of developing Web based enterprise application programs which base on the J2EE(Java 2 Platform, Enterprise Edition),and EJB architecture is the main distributed module model which build the transactional application programs.
