基于构件的信息系统体系结构模型

在分析信息系统层次结构的基础上，提出信息系统结构的层次化构件模型；描述了基于构件化层次模型的信息系统的抽象层次、结构元件、结构特征，给出了不同抽象粒度构件的形式化描述方法、构件连接的形式扣方法、基于企业模型的系统软件组织方式；为信息系统的设计与开发提供了参考模型。初步应用表明，层次化构件模型的设计思想架起了管理系统与信息系统之间的桥梁。提高了信息系统适应性扣开发效率。

Component Based Architecture of Information Systems

After analyzing hierachical structure of information systems, a hierachical component based architecture model is presented. The abstract levels, architectural features, describing methods are thoroughly discussed. It describes different levels of components and their formal specifications, typical compound methods of components and organizing styles of IS based on this model. It also offers a reference model for the design and development of information systems. Preliminary application of this model shows that it can bridge the gap between management system and information systems, thus greatly improve the adaptability and development efficiency of IS.
