/**
* @deprecated As of release 1802, replaced by {@link #(org.onap.appc.dao.util.dbcp.DBConnectionPool)}
* <p>
* This class provides the ability to access mysql database which has been @Deprecated because
* {@link #getConnection(String)} for each database request is not a good practice especially
* on appc performance.
* <p>
* If you would like to use appcctl (mysql database), bundle:appc-data-access-lib has created
* a database connection pool bean and exported as a service by using blueprint.
* If you would like to create a new database connection pool, refer to the way mentioned above.
* {@link org.onap.appc.dao.util.api.DBConnectionPoolService} has an example of how to use
* the connection pool.
