Fang Yi-xin · IEEE Software · 2012
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
