信息系统体系结构的探讨

A study the information system architecture

目的探讨信息系统体系结构框架及构成。方法从系统角度,通过考虑信息系统要素及构成,来探讨信息系统体系结构框架。结果从系统角度提出了一种较全面的信息系统体系结构框架,信息系统体系结构建立在企业架构基础之上,它包括信息系统的概念结构、基础设施架构、信息资源结构和软件架构等。信息系统体系结构表现出确定的架构模式,同时需要Corba,DCOM,EJB,Web服务等分布架构技术的支持。结论对信息系统学科的研究和信息系统开发具有重要意义。

Aim To discuss various frameworks and forms for information system architecture. Methods From the viewpoint of systems, the information system architecture is studied by considering the elements and forms of information systems. Results A kind of overall framework of information system architecture is proposed from the perspective of systems. The enterprise architecture is based on the informations system architecture ,which includes conception construction, basic facilities architecture,information resource construction and software architecture. The information system architecture presents a determined architecture pattern and it needs supports from distributed architecture technology, such as Corba, DCOM, EJB, Web Services. Conclusion It is meaningful and useful to the research of information systems discipline and the development of information systems.
