中文摘要：

为了更好地满足大量联机并发访问数据库并从中获取位置信息的需求，该文在分析LBS系统整体结构框架的基础上，对其中的关键技术——数据库连接池进行了研究。通过结合车辆定位平台的实例，设计和实现了数据库连接池，并验证了其有效性。

英文摘要：

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.
