* The following class provides an example of using the DatabaseMetaData
* class.
*
* The DatabaseMetaData class is used to determine the capabilities of a JDBC
* driver and it database during runtime. If a given method of this interface
* is not supported by the JDBC driver, the method will either throw an
* SQLException, or in the case of a method that returns a result set, it
* may return null.
*
* Some of the methods take search patterns as its arguments. The pattern
* values used can be the SQL wildcard characters % and _. Other search
* arguments accept an empty set ("") when the argument is not applicable, or
* null to drop the argument from the search criteria.
*
* All methods can throw an SQLException.
