摘要
介绍构造两级数据库系统的设计方案,重点研究数据库设计、同步和实现技术。该方案支持两级数据库之间数据的双向复制、局部复制,支持异种数据库系统间的同步,可以处理任意类型的数据项,并提供机制来处理同步过程中的各种异常情况,具有较高的扩展性、易用性,并在实际项目中运用。
Introduces a solution to construct a two-level database system, focus on database design, database synchronization and implementation technique. This solution supports double-direction replication, part replication between two-level database, supports replication between heterogeneous database systems, can handle variant type of data item and provides a mechanism to handle exception in synchronization. This solution is extensible, easy to use and applied in actual project.
