Mobile Database Application Research Based on GIS

This article discussed many problems which exist in the process of realizing GIS datapsilas synchronization based on the characteristics of GIS spatio-temporal data and mobile database, such as how to improve the efficiency of data visiting and updating and guaranteeing data transmissionpsilas reliability and uniformity and so on, proposed the multithread technology, three-layer duplication/buffer architecture, conflict detection mechanism and GIS mobile databasepsilas optimization and so on, obtaining good effect and having practical significance to the application research based on the GIS mobile database. Along with rapid development on GIS technology and wireless communication technology, applications of these technologies become possible. This article studies data synchronization and exchange in the mobile database by combining wireless communication technology with mobile end client.
