| 40 | * The Java SQL framework allows for multiple database drivers. Each driver |
| 41 | * should supply a class that implements the Driver interface |
| 42 | * |
| 43 | * <p> |
| 44 | * The DriverManager will try to load as many drivers as it can find and then |
| 45 | * for any given connection request, it will ask each driver in turn to try to |
| 46 | * connect to the target URL. |
| 47 | * </p> |
| 48 | * |
| 49 | * <p> |
| 50 | * It is strongly recommended that each Driver class should be small and |
| 51 | * standalone so that the Driver class can be loaded and queried without |
| 52 | * bringing in vast quantities of supporting code. |
| 53 | * </p> |
| 54 | * |
| 55 | * <p> |
| 56 | * When a Driver class is loaded, it should create an instance of itself and |
| 57 | * register it with the DriverManager. This means that a user can load and |
| 58 | * register a driver by doing Class.forName("foo.bah.Driver") |
| 59 | * </p> |
