Internet/Intranet环境下管理信息系统研究

研究了管理信息系统(MIS)的一种ⅡMIS新型运作模式。ⅡMIS是Internet/Intranet与传统MIS的有机结合。讨论了ⅡMIS的结构模型,提出一种复合MIS结构模型,并阐述ⅡMIS的功能,指出ⅡMIS是一种分布式、集成化的全方位服务信息系统,该文还讨论ⅡMIS的实现技术和ⅡMIS的安全性问题,着重分析Web数据库访问技术和分布式计算技术,探讨ⅡMIS的各种安全机制,其安全机制的结合形成了ⅡMIS的安全体系。

A Study of Management Information System in Internet/Intranet Environment

This paper studies a new operation model of MIS-ⅡMIS, which is the combination of Internet/Intranet and traditional MIS. The architecture model of ⅡMIS is discussed, and also, a compound MIS architecture model is put forward. Then the function of ⅡMIS is explained. ⅡMIS is a distributed, integrated full-service information system. The realization techniques and security of ⅡMIS are discussed. Web-based database access technology and distributed computing technology are primarily analyzed. Various ⅡMIS security mechanisms are also discussed. The combination of security mechanisms forms ⅡMIS security architecture.
