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