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