To begin working with JDBC, a Connection Object needs to be acquired. The Connection Object symbolises the network connection to the database that holds the data to be manipulated.

When using JDBC, the generation of connections is created by the DriverManager, which needs to be instructed about which JDBC drivers it should connect to. This can be done simply by using Class.forName() on the Class that instigates the interface for the java.sql.Driver. For example MM.MySQL uses the Class called org.gjt.mm.mysql.Driver.
