ODP系统中的观点及观点规范语言

开放分布式处理ＯＤＰ的目标是给应用程序间提供一个一致的接口模型，以实现分布透明性、互操作性和可移植性。开放分布式参考模型ＩＳＯ ＲＭ－ＯＤＰ提供了一个分布式系统的框架，从五个不同的观点描述ＯＤＰ系统，并提出相应的规范语言的概念和构造规则以便对该观点进行描述，本文首先介绍了这五种观点及相应的规范语言的概念和构造规则，并讨论了它们之间的关系。

VIEWPOINTS AND VIEWPOINT LANGUAGES IN ODP SYSTEMS

The Open Distributed Processing (ODP) aims to provide a consistent interface model for the distributed application programs to achieve portability, interoperatability and distribution transparency. ISO RM--ODP gives a framework of distributedsystems, and uses five viewpoints to abstract the ODP systems. It also proposes concepts and structuring rules of the corresponding viewpoint languages to specify the viewpoints. This paper introduces five viewpoints and the corresponding languages' conceptsand structuring rules. The relationship between the viewpoint languages is also discussed.
