Running a Forms Developer Application describes how to run and navigate an Oracle Forms application. The key points are: 1. A Forms application runs in a browser using a Java applet. The Forms servlet and listener servlet manage communication between the applet and runtime engine. 2. Users can navigate forms using menus, toolbars, buttons or function keys. Queries return all records by default or can be restricted. 3. There are two modes: enter-query allows queries but not changes; normal mode allows queries, changes and committing updates to the database. 4. Errors are displayed using the Help > Display Error menu. Records can be inserted, updated and deleted then
