摘要 并发操作是协同CAD系统中至关重要的问题。该文提出了并发操作控制机制的设计原则,阐述了基于语义的并发控制机制利用嵌套事务来解决传统图档事务并发控制中的数据一致性低、中间版本不易维护等问题,结合实际给出了博士CAD系统中并发控制的系统模型,并作了相应的说明。 Concurrent manipulation control scheme is crucial for CAD system. This paper proposes several design considerations for concurrency manipulation control scheme, and introduces the nested transaction of a semantic-based concurrency to solve the problem of lower consistency and difficulty in managing middle version and so on. The model for concurrent DorCAD system is described.
