图案协同设计中的数据处理技术

图案的协同设计是计算机支持的协同工作的一个典型的应用，对数据的并发访问控制是其中心问题。本文基本作者开发的一个基于Ｉｎｔｅｒｎｅｔ的图案协同设计原型系统ＣｏＤｅｓｉｇｎ提出了在协同过程中，将用户对数据的操作行为表述为数据库事务操作的思想，并形式化地研究了表达操作行为的事务模型，较好地解决了协同数据处理问题。

Data Processing Technology in Cooperative Pattern Design

Cooperative pattern design is one of the typical applications of Computer Supported Cooperative Work(CSCW),and the concurrent accesses and controls of cooperative data are the central problem.In this paper,based on an Internet based cooperative pattern design protocol system(CoDesign)developed by the authors,an idea of treating the data operations by the users as the operations of database transaction processing in the cooperative process,and formally research the transaction model of describing the operational behavior.This technology can solve the cooperative data processing problem effectively.
