Abstract: As a standard core specification to access relational database, JDBC(Java Database Connectivity) plays an important role in the Java platform applications. However, due to its own deficiency, complexities are introduced into the applications directly based on JDBC API(Application Programming Interface). Some related issues when using JDBC API to access database were discussed, and template method and callback functions were adopted to wrap and implement API. Then, the performances between using JDBC API directly and using wrapped API were compared. It is proved that the latter approach has better performance in application.
