/** provides comprehensive information about the database as a whole.


	<p>Many of the methods here return lists of information in
	the form of
	<type scope="com::sun::star::sdbc">XResultSet</type>
	objects.
	You can use the normal <type scope="com::sun::star::sdbc">XResultSet</type>
	methods such as
	<member scope="com::sun::star::sdbc">XResultSet::getString()</member>
	and
	<member scope="com::sun::star::sdbc">XResultSet::getInt()</member>
	to retrieve the data from these XResultSets. If a given form of
	metadata is not available, these methods should throw a
	<type scope="com::sun::star::sdbc">SQLException</type>
	.
    That a value of <type scope="com::sun::star::sdbc">XResultSet</type> is <NULL/>
    can be chaked with the method <member scope="com::sun::star::sdbc">XResultSet::wasNull()</member>.
    In the text only "(may be <NULL/>)" is mentioned for this case.
	</p>
	<p>Some of these methods take arguments that are String patterns. These
	arguments all have names such as fooPattern. Within a pattern String, "%"
	means match any substring of 0 or more characters, and "_" means match
	any one character. Only metadata entries matching the search pattern
	are returned. If a search pattern argument is set to <VOID/>,
	that argument's criteria will be dropped from the search.
	</p>
	<p>
	A
	<type scope="com::sun::star::sdbc">SQLException</type>
	will be thrown if a driver does not support
	a meta data method. In the case of methods that return an XResultSet,
	either an XResultSet (which may be empty) is returned or a
	SQLException is thrown.</p>
