First, this article discusses three kinds of inconsistency that may result from operating system conflict; then briefly introduces some control methods of concurrency in CSCW system and describes two models which are based on different distribution structure-integrated consistency model and local consistency model; and, finally, the article presents a tree structure for achieving local.

The multi-versioning technique based on object replication strategy can meet consistency model while the conflict operations occur in the cooperative graphics editing systems(CGES),but it does not efficiently solve conflict between non-geometry attribute operations and complex graphics objects.

The paper proposes a set of model consistency checkout rules.

Model consistency is one of the main sectors that affects UML multi-view modeling in the larger complicated software system.

However, UML is at last a semi-formal language, so it’s difficult to maintain model consistency.

A new memory consistency model,named stream consistency for the stream programming model is proposed.

This paper proposes a new framework of memory consistency models named S 3 C Framework.

Firstly,the formal description of the method is given,and the ontology unified model,the atomic change and its conflict resolution method are established.
