摘要: 针对传统的紧耦合Web系统模式存在的问题,该文提出了一种符合J2EE规范的、松散耦合的多层分布式系统,利用XML来分离业务逻辑和数据库。系统配置、数据传输以及层次之间的接口部分或全部由XML来实现,研究并实现了XML与异构数据源的转化机制,并将其应用到了Web应用系统——MEDLOG中。

关键词: XML, 分布式系统, Web应用

Abstract: Aiming at the disadvantage of traditional, this paper presents close coupling Web application system model based on a J2EE and loose coupling multi-storey distributed system, which separates business logic layer from database layer. It implements system configuration, data transmission, inter-layer interface with XML technology. A data transfer strategies between XML documents and heterogeneous data source is discussed and implemented. The architecture is applied to the Web application system——MEDLOG.

Key words: XML, Distributed system, Web application
