Java分布式计算技术的分析与比较

The Analysis and Comparison of Several Distributed Computing Technologies in Java

一、多层体系结构的应用系统传统的应用系统基本上是单一结构或C/S结构的系统,这种结构的应用系统其构造和维护一般很难,即使是简单的改动也需要对整个系统进行重编译和测试,因此越来越多的分布式应用系统开始采用多层体系结构。三层体系结构的分布式应用系统运行于多台计算机上。一般地,三层结构的应用系统包括用户界面层、事务逻辑层和数据存储层:

The Java distributed computing technology represents one of the advanced technology which makes the developing of complicated network applications easy. This paper first gives the rationale of the multi-tier architecture distributed applications, then analyzes and compares with several distributed computing technologies in Java such as Java RMI, Java IDL, EJB and discusses the main characteristics of these technology.
