摘　　要：文中结合在实验室自行开发的移动数据库原型SwiftDB,介绍了移动数据库系统的发展现状,提出了基于两级复制模型的同步解决方案双向复制,并根据不同应用环境采用不同方法加以实现,在维护数据一致性的同时也提高了系统的性能。Combined with a prototype of mobile database system SwiftDB developed in the lab environment, the current situation of the development of embedded database system was introduced. Then a solution for data synchronization based on the two-way replication was brought forward. Besides, some different implementation methods for different application environments were also given, which benefited not only the maintenance of data consistency, but also the performance of the whole system.
