ndroid终端与服务器数据同步系统设计

ndroid has been widely ued as one of the mainstream mobile terminal platform in the field of transport.However, the mobile terminal itself has a too small data storage capacity to store large amounts of data, which requires data synchronization technology to synchronize data stored in terminal to the server, in order to ensure long-lasting data storage.The main work of this article is to established a one-way data synchronization system based on analysis of basic daily operational requirements of a transporation.First, capture data changes of databases in Android PDA terminal by SQLite trigger, and then find the new added records of data changed table by data changes, send the data to Web Service interface of the server by HTTP protocol.Finally, Web Service call appropriate method to store data in database to achieve data synchronization.PDA terminal uses SQLite database to store data, the server uses SQL Server database to store data and the Web Service uses C# to develop.After testing, the system can achieve synchronization from Android terminal to the server.
