Domain modeling and automated software constructionoffers significant potential for rapidly producing high qualitysoftware systems within many application domains, specially inmature and stable application domains where many variations ofsimilar systems are generated. There is now a clear opportunityto leverage off the work that has already been done inconstructing domain-engineering support tools to integrate theirtechniques and features into a comprehensive domain engineeringand software construction environment.This proposal explores the feasibility of extending the DARE domeanalysis support prototype with the generational features of theIDeA and ROSE model-based construction prototypes for developingthe architecture for a comprehensive domain engineering andsoftware construction environment.The envisioned architecture will support representation of domaincapabilities in domain specific terminology, requirementsanalysis and reuse, verification consistency of commonalities andvariabilities, and feature selection and integration.The proposed environment will stress the integrated wide-spectrumsupport for domain engineering and model-based softwareconstruction. It will be based on m open architecture concept sothat DARE, ROSE, and other domain engineering tools can later beintegrated and tested. Phase II development and commercializationplans are included.Potential commercial applications of the research:New generationof CASE tools supporting reuse and domain engineering, front endenvironments for existing CASE tools; development of new methodsand techniques for domed engineering; an improved understandingof the economic potential of domain engineering and automatedsoftware construction tools.
