基于分布式数据库的连锁超市管理系统设计与实现

Design and Implementation of Supermarket Chains Based on Distributed Database Management System

连锁超市具有多终端、地域分散、数据量大,但需要集中管理的特点。因此,该系统通过采用终端＋应用程序服务器＋数据库的三层设计模式的方法实现了单间分店系统的设计,通过分布式数据库查询的方法实现了多间分店数据的统一查询,从而实现数据的互联互通。通过分布式数据库查询的方法把不同地域结构相同的系统的数据进行统一管理。

The supermarket chain has multi-terminal,geographically dispersed,the amount of data,but the need to focus on the management characteristics.Therefore,the system is achieved through the use of the terminal ＋ application server ＋ database of three-layer design model with a single branch system design,distributed database query outlets unified data query,enabling the interconnection of data interoperability.Distributed database query to the structure of the different regions of the same data for unified management.
