WIFI indoor positioning system is one that utilizes a wireless network or a wireless LAN to run a positioning engine to locate tagged objects,which is being used widely in smart home,human resource management. The massive amount of raw positioning data which traditional relational database architecture can't meet the requirements of performance.So this paper proposes a middleware used in data process based on distributed architecture,which provides the data service, such as engine-application message scheduling and database interaction. To better process the massive amount of data produced by the indoor positioning engine, the middleware distributes the data to different routers,partitions or tables using methods such as read-write splitting and intra-database table partitioning. This makes database access significantly easier, and to some extent overcomes the performance constraints of traditional relational databases in large-scale data processing. The middleware provides module based on Map Reduce for big data analysis,in order to make the third-pary application significantly simple and optimize system performance.
