We have already seen that JDBC DriverManager can is used to get relational database connections. But if it comes to actual programming, we want more than just connections.Most of the times we is looking for loose coupling for connectivity so, we can switch databases easily, connection POOling for transaction management and distributed systems support. JDBC DataSource is the preferred approach if you be look
