Study Of Process Information Integration Management Technology For Virtual Enterprises

As the a new enterprise running mode, virtual enterprise has a promising future, however, the most important part of the problem which has always been the obstacle for virtual enterprises development is the integration and share of information (Manufacturing information, Management information etc.) among which process information is also a very critical aspect. And it finally comes to the problem of how to attain the integration of distributed and inhomogeneous databases. Fortunately, the CORBA technology puts forward an excellent plan to solve this kind of problemFirst of all, the article not only narrates the task's backgrounds and the relevant technologies' progress backgrounds, but also researches on enterprises and process information system Further more it sets up a process information model for the system and create the process data database according to the process information model. Then, it probes into the problem of how to implement the access of database through the middleware of CORBA. After that it analyzes the system requirements and system functions and sets up a system framework. During the implementation course of the system, all kinds of models are established by means of UML to guide the process of system's development and implementation. At last, the security problem of the system is also discussed...
