多数据库中间件中分布异构数据缓冲区系统的实现

Realization of distributed and heterogeneous data buffer system in multi-database middleware

实现了多数据库中间件中分布异构数据缓冲区,该模型能够实现分布异构数据对象的数据双向同步/异步更新机制;采用的全局数据对象存储模型和缓存管理使数据在缓冲区存储并被用户高效快捷地访问;实现了全局事务管理策略,包括局部代理的设计、全局事务的并发控制、全局事务提交协议等。

The realization of the model of distributed and heterogeneous data buffer（DHDB） enabled bidirectional synchronous/asynchronous update of distributed and heterogeneous data; the use of global data object model and data object cache management enabled data store in the cache and assessed efficiently and quickly; realized global transaction management, including design of local agent, global transaction parallel control and global transaction commitment protocol.
