Design And Implement Of Enterprise Distributed Database Access System

Along with information expanding and network popularization, the way that accessing single database doesn't satisfy the demand, people is increasing the requirement to access distributed database that locate at different area. The very important question when you design a distributed database is how to make users access data conveniently and efficiently, users aren't conscious of accessing data locating different server, they manipulate distributed database as if manipulate local database. According to this goal, this paper discuss distributed database theory, and bring forward a idea based on MS SQL Linked Server Concept to access distributed data, at the same time discuss some detail question when implement this theory and newly accessing data technique.Meanwhile, the fulfillment of the first phase development of technique information system of the ministry of communications First Navigation Engineering bureau indicates the realization of this paper's research. This system has been tried out, which is up to now stable. It meets the enterprise needs.
