NEWCOM:AN ARCHITECTURE DESCRIPTION LANGUAGE IN CLIENT/SERVER STYLE

本文介绍一个客户／服务器风格的体系结构描述语言NEWCOM．它的抽象级别介于需求描述和第四代语言之间．NEWCOM程序从宏观上描述一个在客户／服务器环境下运行的MIS．它支持多种组件，并为这些组件提供了若干连接机制．NEWCOM涉及数据仓库技术及数据库变换技术，支持异构的网络结构和数据库平台，有助于实现企业的整体解决方案．NEWCOM具有通用性和开放性，既可作为软件人员的设计蓝图，又可直接为用户生成MIS系统．

This paper introduces an architecture description language, NEWCOM,which is a moderate abstract level between requirement specification and 4GL.NEWCOM programs describe the global architecture of MISs in client/server style.NEWCOM is platform-independent. It supports heterogeneous network structure and database platform. NEWCOM includes various components and connectors for them. Data warehousing and database evolvement technique is also tackled, which is helpful to form a global solution for enterprises. NEWCOM has openness, which is not only used as a designing document, but also used to generate MIS directly.
