Research of Process Modeling and Version Control for the Distributed Collaborative Design System;

In this paper, after analysing the basic problems in version control, the implementation of version control in SuperOODB system is discussed in detail.

This paper firstly introduces the application of version control mechanism in dealing with the problem of "the long time process" in geography information system.

The Method of A Version Management Based on Design Knowledge;

Study and application of product version management in PDM;

Research on spatial data version management based on ArcSDE;

In this paper, on the basis of analysing the characteristics of the document management in cooperative design, a product data model based on the structure of product and a mode of document management are presented, and the data models of part as well as assembly and document are established, and the respective edition management is also be analysed.

For solving the long work handling in mechanical design process,edition management and automaticly generating calculating instruction,through development and application in hoisl mechanism system,the method proves to be successful.

Because the edition management method of SDE is adopting the addition database, it engenders many different editions with the nimiety of the domanial historical data when using edition management method of SDE of the ESRI company, at the same time, it slows down the speed of transference and.
