	<type scope="com::sun::star::sdbc">ResultSet</type>.


	<p>
	It acts like a typical bean. Before you use the RowSet, you have to specify a
	set of properties like a DataSource and a Command and other properties known of
	Statement.
	<br/>
	Afterwards, you can populate the RowSet by its execute method to fill the set
	with data.
	</p>
	<p>
	On the one hand, a RowSet can be used as a short cut to retrieve the data of a DataSource.
	You don't have to establish a connection, create a Statement, and then create
	a ResultSet. On the other hand, a rowset can be used to implement capabilties for
	a result set, which are not supported by a driver result set, like caching
	strategies or update capabilities.
