Unlike Delphi and ADO-based Advantage applications, which support a wide range of navigational operations, JDBC supports only simple navigation. Specifically, the ResultSet class permits you to navigate forward through the records of the result set, and if the cursor is bidirectional, you can move forward and backward using methods with names such as first, next, last, and previous. The use of simple forward navigation is demonstrated in the following section.

NOTE: Some classes in Borland's DataExpress in JBuilder support additional navigational capabilities, such as filtering. These classes are not, however, native to JDBC.
