数据库连接池在电子病历共享系统中的应用研究

his paper build a database connection pool system, which can finish the management of different databases connection, meet the application's access requirements to multiple databases, and can easily manage the database change, improve system scalability. Designed a optimization scheme of database connection pool, implemented the reuse of database connections through reference counting method. Avoid the generation of memory leaks and reduced the system overhead，Improved the efficiency of database access and system performance. Database connection pool system provides the interface and the concrete implementation strategies of the monitoring system, which improved system maintainability and reusability.
