/**
 * The interface that adds support to the JDBC API for the
 * JavaBeans™ component model.
 * A rowset, which can be used as a JavaBeans component in
 * a visual Bean development environment, can be created and
 * configured at design time and executed at run time.
 * <P>
 * The <code>RowSet</code>
 * interface provides a set of JavaBeans properties that allow a <code>RowSet</code>
 * instance to be configured to connect to a JDBC data source and read
 * some data from the data source. A group of setter methods (<code>setInt</code>,
 * <code>setBytes</code>, <code>setString</code>, and so on)
 * provide a way to pass input parameters to a rowset's command property.
 * This command is the SQL query the rowset uses when it gets its data from
 * a relational database, which is generally the case.
 * <P>
 * The <code>RowSet</code>
 * interface supports JavaBeans events, allowing other components in an
 * application to be notified when an event occurs on a rowset,
 * such as a change in its value.
 *
 * <P>The <code>RowSet</code> interface is unique in that it is intended to be
 * implemented using the rest of the JDBC API. In other words, a
 * <code>RowSet</code> implementation is a layer of software that executes "on top"
 * of a JDBC driver. Implementations of the <code>RowSet</code> interface can
 * be provided by anyone, including JDBC driver vendors who want to
 * provide a <code>RowSet</code> implementation as part of their JDBC products.
 * <P>
 * A <code>RowSet</code> object may make a connection with a data source and
 * maintain that connection throughout its life cycle, in which case it is
 * called a <i>connected</i> rowset. A rowset may also make a connection with
 * a data source, get data from it, and then close the connection. Such a rowset
 * is called a <i>disconnected</i> rowset. A disconnected rowset may make
 * changes to its data while it is disconnected and then send the changes back
 * to the original source of the data, but it must reestablish a connection to do so.
 * <P>
 * A disconnected rowset may have a {@code Reader} (a <code>RowSetReader</code> object)
 * and a writer (a <code>RowSetWriter</code> object) associated with it.
 * The {@code Reader} may be implemented in many different ways to populate a rowset
 * with data, including getting data from a non-relational data source. The
 * writer can also be implemented in many different ways to propagate changes
 * made to the rowset's data back to the underlying data source.
 * <P>
 * Rowsets are easy to use. The <code>RowSet</code> interface extends the standard
 * <code>java.sql.ResultSet</code> interface. The <code>RowSetMetaData</code>
 * interface extends the <code>java.sql.ResultSetMetaData</code> interface.
 * Thus, developers familiar
 * with the JDBC API will have to learn a minimal number of new APIs to
 * use rowsets. In addition, third-party software tools that work with
 * JDBC <code>ResultSet</code> objects will also easily be made to work with rowsets.
 *
