摘　　要：基于分布式数据库的综合信息服务系统,由物理层、数据层、应用支撑层、业务层及应用层组成。其核心部分—数据库系统的设计采用本地数据库与远程分布数据库相结合、多级数据库级联的方式,通过网络或移动存储设备实现各级数据库之间的信息交换。其体系结构以B/S结构为主,融合C/S结构,实现的关键技术涉及数据分片技术和分布式数据库同步技术。The integrated information service system based on the distributed database system consists of physical layer, data layer, application support layer, business layer and application layer. The design of database system, which is the key component of the integrated information service system, explores the way of local database combined with remote distributed database and uses multi-level databases. It realizes the information exchange between different level databases through network or mobile equipment for stock. The architecture of database system mainly uses the structure of C/S and integrates the B/S structure. The key technologies contain the fragmentation of data and the synchronous technology of distributed database.
