Model-based Object-oriented Requirement Engineering and its Support to Software Documents Integration

Abstract Maintaining uniformity of software requirement documents with artifacts from other phases of software life cycle is a very important, however, still a difficult and time-consuming task. Most requirement documents were written in ambiguous natural language which is less formal and imprecise. Without proper modeling, the requirement knowledge is laboriously captured and thus the following formal integration with other artifacts is infeasible. In this paper, we propose a Model-based Object-oriented approach for Requirement Engineering to support and improve the maintenance and consistency of software requirement documents, as well as the consistency with other artifacts through software life cycle. By applying modeling and Object-Oriented technologies to requirement, the domain knowledge can be captured in a well-defined model. The completeness, consistency, traceability and reusability of requirement and its integration with the artifacts of other phases thus can be improved.
