This research addresses a major shortcoming in today's analysis techniques. Neither structured nor object-oriented analysis techniques provide a formal process to identify relationships in a system being modeled. Existing techniques leave the relationship determination implicit; they are supposed to appear as a byproduct of the other analysis activities. We propose a comprehensive, systematic, domain-independent analysis technique, relationship analysis (RA), which focuses exclusively on a domain's relationship structure. RA serves two major purposes. First, it helps users, analysts and designers develop a deeper understanding of the application domain through making the relationships explicit. Second, RA results in fuller and richer application analyses and designs. Integration of RA with the object oriented analysis techniques like UP can provide a complete system architect solution.
