Bean as Datasource

2.  The main motto of this PPT is How to use
Bean as Datasource in Database connector in
our applications.

3.  The Database connector allows you to
connect with almost any Java Database
Connectivity (JDBC) relational database using
a single interface for every case. The
Database connector allows you to run diverse
SQL operations on your database, including
Select, Insert, Update, Delete, and even
Stored Procedures.
