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")
