用Java实现基于CORBA的分布式图书馆查询系统

Implementing CORBA -based Distributed Library Query System in Java

CORBA是由OMG发布的一项用于分布式系统开发的技术规范,在解决异构平台、集成已有系统方面有着独特的优势。但其复杂性阻碍了它在图书馆界的广泛应用。本文从整体的角度讨论了用Java实现一个基于CORBA的分布式图书馆查询系统的具体过程,以期达到抛砖引玉的作用。还简单介绍了另外两种常用的分布式系统开发标准COM/DCOM和SOAP,并对三者进行了比较。

CORBA is a standard for distributed system developed by the Object Management Group (OMG). It has specific advantage in terms of resolving platform heterogeneity and integrating existing systems. But its intricacy cumbers its widely use in library sphere. This paper discusses the whole process about how to develop a CORBA -based library query system in Java. It intends to be a reference for others in library sphere who are interested in CORBA. This paper also introduces two other common standards--COM/DCOM and SOAP, comparing with CORBA.
