Combining AST and Lock Techniques to Maintain Consistency of Multiple Objects in Replicated CAD Environments
This paper introduces combining address space transformation strategy with lock strategy to maintain the consistency of both simple objects and complex objects in replicated CAD environments. This combination adapts AST strategy from group editor field to CAD environment, gurantees the high concurrency of the replicated architure, and provides relatively effective strategy to process complex objects. The combination process of AST and Lock strategy is also decribed in detail in the paper.
