A custom application was created for this business task to provide more sophisticated
processing and database integrity than is available with a DB requester application.
For example, pressing F5 (Calculate Tax) will calculate and display the tax on the sales
price entered. Pressing F12 (Delete) will only delete the vehicle after all references to it
are removed from other places in the database.
Components of a Custom Application
A custom Pathmaker application is usually composed of:
One or more menu requesters (optional)
One or more transaction (TRNS) requesters
One or more custom services (packaged into custom servers)
All of these components are created by application developers using the Pathmaker
product.
Menu Requester. The menu requesters used as components of custom Pathmaker
applications are the same as those described for DB requester applications.
