Project Information Communication System In A Virtual Environment

As the drastic competitions of trades in the whole world, trades' environment of survival and development become more and more changeable. Under this background, the traditional environment of project management is being transformed into virtual environment step by step. Virtual environment creates a kind of communication way of surmounting time and region. Furthermore, it dispelles all sorts of barriers of the information sharing and it changes the business communication way in the project greatly.Therefore, the research of virtual project information communication system (V_PICS) has theoretical meaning.Firstly, this paper compares the popular methods in IS development and clarifies their advantages and disadvantages. According to the system's characteristics, a comprehensive method, which combines Structured System Development Methodologies (SSDM), Prototyping and UML (Unified Modeling Language) for OO (Oriented Object), is adopted to develop this system. Secondly, this paper studies the function of project information flow in the project flows, and it also shows the classification, characteristic and forms of project information flowing. After that, it refers the existing problem under the traditional environment and raises virtual environment in project. Thirdly, this paper studies how to analyse and design V_PICS including the relationship between PICS and PMIS, overall planning, system analysis and system designing. After that, it shows the technology on B/S mode and the interface technology between web server and database server, the emphasis of which is the application of JSP used in V_PICS. Finally, the paper describes the executive environment of the system and discusses several critical problems.
