Abstract: In order to satisfy the demands of multi-clients’ concurrent database access to acquire location-based information, the key technology of database connection pool is analyzed on the basis of the architecture of LBS. The design and implementation of database connection pool are done through an instance of vehicle positioning platform, which proves the efficiency of this method.
