摘要
针对移动数据库同步服务器中存在大量数据冲突和事物频繁需要回滚处理的问题,在目前通用的三级复制模型基础上,引入本体论技术,提出了一种同步服务器的设计方法。按该方法设计的同步服务器通过建立本体来分析移动事物操作的语义信息,并按照语义信息之间的关联来检测和解决移动事物间的数据冲突。经验证其方法可有效的解决数据冲突问题。
Aiming at data collision and frequent re-rolling treatment, based on the existing general three-grade replication model, a design method of synchronization server with ontology technology is put forward. The synchronization server analyses the semantic information of mobile manipulation by constructing ontology, detects and solves data collision of mobile transactions according to the relationship between semantic information. The experiment shows that the method proposed can solve the problem of data collision effectively.
