Using Automatic Error Handling in Rapid Application Development

Abstract

Many recent data processing applications have been designed for client-server computing graphical user interface: and the server program is usually a database with related procedures. By applying rapid application developmetn (RAD) technique, the client side of data processing applications can be crafted quickly. Potential users can then involve in the development process as soon as possible. However, early releases of portotypes tend tcontain bugs that make the prototyper difficult to use. This paper presents our experience in using automatic error handling ofr RAD. We define automatic errorhandling as two steps: (1) report errors and (2) continue execution. Our implementation uses Microsoft Visual Basic and its error handling consturcts. Preliminary experience on the implementation is also reported.
