Sybase provides a complete development environment. In addition to control over server and database access through DB-Library/C, Sybase offers optional tools for creating forms-based, event-driven applications. These tools are APT-Edit and the APT-Library™/C set of routines. APT-Edit is an editor for creating forms and specifying event-driven processing. APT-Library/C is a set of C routines that support forms-based, event-driven processing. Just as DB-Library/C routines provide an application with access to servers and database objects, APT-Library/C routines provide access to a form and its objects. A forms-based application typically contains both APT-Library/C and DB-Library/C routines. For more information, see the APT Workbench User’s Guide.
