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.
