The desgin of embedded SQLite3 and application of Commodity Rapid Positioning System based on Wi-Fi technology

With development of embedded database technology, network performance of mobile-device and standardization of data management have a significant change. For characteristics of high reliability and real-time that Wi-Fi Commodity Rapid Positioning System terminal has, embedded database SQLite3 is proposed to manage system bulk data like storing, operating maintaining. Combined with enterprise requirement, this paper analyses the processing in database design and SQLite3 operate procedure under ARM-WindowsCE5.0. Besides the detail of porting SOLite3 based on ARM-Windows CE5.0 is also stated in the paper. Finally the test results show that SQLites3 embedded in the Product Rapid Positioning System is stable and reliable.
