Examples of java.sql.Driver

java.sql.Driver
An Interface to a JDBC Driver.
The JDBC Driver uses URLs to specify the location of specific data. URL format typically takes the form "xxxx:yyyy:SpecificData", where "xxxx:yyyy" is termed the subprotocol and is normally the same for all uses of a particular driver. "SpecificData" is a string which identifies the particular data source that the driver should use.
