Distributed Management Information System Techniques in e-Business

Based on the study of the Distributed Management Information System(DMIS) in e-business, the two key techniques are discussed, such as role-based permissions management (RBPM) and Component-Oriented Updating Techniques(COUT). The method of realizing the work flow through RBPM is provided in this paper. The concept of authority is broken down to each operating procedures; realization of user operational procedures are reflected in the achievement of right-matching and right-series. To update the variable system timely, an updating strategy, which is based on the distributed object technology, is presented also. By this strategy, a COM component-oriented updating system framework based on distributed object technology is implemented. On the basis of Observer design pattern, the framework takes advantage of the remote processing technology to implement the dynamic updating of software based on component. Both the theory and practice proof that it is an efficient solution to eliminate the disadvantage of traditional way of software updating.
