An ada object-based analysis and design approach

ABSTRACT

Cost and quality are becoming increasingly important for companies developing software for the Federal Government. Since much of the software developed for the Government must he written in Ada, software engineers and managers are searching to improve the process of developing Ada systems.Based on the potential of object-oriented methods-better maintainability, reusability, and intellectual control for large complex systems-we have implemented and are continuing to evolve a real-time object-oriented approach for developing Ada systems. Our process borrows heavily from the work of others and offers unique techniques for expressing object behavior, verifying and validating the object-oriented models, and mapping the object-oriented requirements model to Ada constructs. The approach we present in this paper incorporates object-oriented methods for both requirements analysis and Ada design, and focuses on:•Ada considerations for the object-oriented models•Transitioning from the requirements analysis model to Ada design with a minimum of corner-turning•Real-time behavior specifications for object services•A common method for verifying the requirements analysis model and validating the design model.
