Software Engineering: Integration Requirements

This paper presents a discussion of software integration requirements, with an emphasis on the requirements of post-factum software systems integration. The problem is defined; the requirements and associated issues are discussed. Formality as a major requirement of software integration is emphasized and a formal approach, called Compositional integration, is introduced. The requirements for integration of redundant software components, developed using diverse software engineering methodologies, into a fault tolerant system is described. Finally, the paper concludes with a brief discussion of dynamic integration requirement and some final remarks. Key-Words: Software Integration, Requirements Specification, Software Architecture
