| 摘 要： | 大型分布式系统环境中通常需要在各异地数据库中存储同一数据的不同副本,因此数据同步显得十分重要.在分析比较各种数据一致性方法的基础上,对Oracle9i数据库提供的新功能模块进行了研究,并结合消息队列方法从实践角度提出了基于Oracle高级队列和JMS消息服务机制的数据同步模型.对模型采用的主要技术、工作流程、实现方案做出了详细分析,最后对模型做出了评价和展望.

| Abstract: | Different copies of data always needed to be stored in different database in large-scale distributed system, so the maintaining of data synchronization becomes very important, Based on analysing many kinds of methods in data consistency maintenance, and some research on new function modules of Oracle9i database are done. Combining with message queue theory, a data synchronization model based on Oracle advanced queue and JMS messages service mechanism is presented in application option. The main technology, work flow, implementation scheme in this model are analysed in detail, and also some estimate and prospect are given to this model in the end. |
