A Model Driven Exception Management Framework for Developing Reliable Software Systems

Programming languages provide exception handling mechanisms to structure fault tolerant activities into software systems. However, the use of exceptions at this low level of abstraction can be error-prone and complex leading to new programming errors. In this paper, we present a model-driven framework to support the iterative development of reliable software systems. This framework is comprised of UML-based modeling notations and a transformation engine that supports the automated generation of exception management features for a software system. It leverages domain specific exception modeling languages, patterns, modeling tools and framework libraries. The feasibility of this approach is demonstrated through the development of a case study business application, known as Project Tracker
