分布式异构数据库中移动同步复制冲突消解方法研究

当前移动同步复制冲突消解方法在移动用户逐渐增加、锻炼时间逐渐增长的情况下,会造成很多事物回滚,导致效率降低,冲突消解性能减弱。为此,提出一种新的分布式异构数据库中移动同步复制冲突消解方法,给出分布式异构数据库结构,将全部主机合并成两个逻辑实体,获取移动同步复制数据库系统模型。依据本体概念与关系描述,把某领域的知识统一至一个本体描述的框架下,依据语言记号学理论,用五元组描述本体体系结构。通过本体描述某个领域中事务或概念的不同构成部分和其他部分间的语义关系,通过该关系对分布式异构数据库中移动同步复制冲突进行消解。实验结果表明,所提方法不仅效率高,且有很高的冲突消解性能。

Distributed heterogeneous database in mobile synchronous replication conflict resolution methods

the current mobile synchronous replication conflict resolution methods in mobile users increase gradually, under the condition of exercise time increasing, will cause a lot of things rolled back, lead to lower efficiency, less conflict resolution performance.For this, put forward a new kind of distributed heterogeneous database in mobile synchronous replication conflict resolution method, gives the distributed heterogeneous database structure, will host all merged into two logical entity, for synchronous replication mobile database system model.Based on the concept of ontology and relationship to describe the knowledge in the field of a unified to the framework of an ontology, based on the theories of language semiology, describe architecture of ontology in five yuan group.Through ontology in the field of a transaction or the concept of the semantic relationships between different components and other parts, through the relationship of the distributed heterogeneous database in mobile synchronous replication conflicts is described.The experimental results show that the proposed method is not only high efficiency, and has a high conflict resolution performance.
