30 * The Java SQL framework allows for multiple database drivers. Each driver
31 * should supply a class that implements the Driver interface
32 *
33 * <p>
34 * The DriverManager will try to load as many drivers as it can find and then
35 * for any given connection request, it will ask each driver in turn to try to
36 * connect to the target URL.
37 *
38 * <p>
39 * It is strongly recommended that each Driver class should be small and
40 * standalone so that the Driver class can be loaded and queried without
41 * bringing in vast quantities of supporting code.
42 *
43 * <p>
44 * When a Driver class is loaded, it should create an instance of itself and
45 * register it with the DriverManager. This means that a user can load and
46 * register a driver by doing Class.forName("foo.bah.Driver")
