CIM环境下分布数据一致性的研究与实现

IN CIM ENVIRONMENT,RESEARCH AND REALIZATION OF THE DISTRIBUTED DATA CONSISTENCY

提出了基于信号量的并发控制机制和两个并发控制算法，以解决异构分布的环境下，分布关系间和分布子关系间分布数据的一致性问题，提出在ＣＩＭ环境下，分布数据一致性问题的方法。

A thorough study is made based on the current concurrency control method of processing data consistency at home and aborad, it suggests a concurrency control mechanism based on semaphore and two concurrency control algorithms which are made use of solving consistency problem of distributed among distributed relation and among distributed subrelation in heterogeneous distributed environment. the method which solves consistency problem of distributed data is produced in CIM environment on the basis of this.
