In previous versions (prior to 4.0) of JDBC, to obtain a connection, you first had to initialize your JDBCdriver by calling the method Class.forName. This methods required an object of type java.sql.Driver. DriverManager: This fully implemented class connects an application to a data source, which is specified by adatabase URL.
