Research Of The Distributed Enterprise Computing Model

With the enterprise constant growing size, the scale of information system also increased constantly, so as the development difficultness. Catching on the general structure is more important than the algorism and data structure. The architecture-based software development became a hot spot, there is a trend to be a independent science.This paper discussed the essential requirements of modeling distributed enterprise information system's software architecture and the feasible Unified Modeling Language constructs and techniques. A UML-based software architecture model of distributed information system(USAM) was introduced. The model USAM consists of parts, connectors, interfaces and constraints, described with use case view, logical view, component view and deployment view.It also discussed the USAM-based software development process and the architecture-centered, Object-orient, component-based development strategy. Several mainstream technology on distributed object was analyzed in the software development process. A server model integrating CORBA and EJB norm was adopted in the development. At last a sample about the system information construction of the Wafangdian Bearing Co. ltd. was used to declare the benefit of the model, such as low-time consuming, easy to expanding and deploying.
