Answer» With the JDBC abstraction and DAO module we can be sure that we keep up the database code clean and simple, and PREVENT problems that RESULT from a failure to CLOSE database resources. It provides a layer of meaningful exceptions on top of the error messages given by SEVERAL database servers. It also makes use of Spring’s AOP module to provide transaction management services for objects in a Spring application.
