application server is responsible to manage the connection life cycle. It is generally used with the Web Applications. dataSource tag It is used to configure the connection properties of the database, such as driver-name connection for every database operation. It is a bit slower and generally used for the simple applications. POOLED − For the dataSource type POOLED, MyBatis will maintain a database connection pool. And
