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") |
