We describe our experience with domain-oriented software development in the domain of automatic teller machine applications. We systematically proceeded with development in four phases: domain analysis, domain formalization, domain facility building, and product development. In this development, we built domain facilities consisting of a domain framework and domain CASE (Computer Aided Software Engineering) tools, then employed them for application development. The framework shared about 4% of the application, and the remaining 96% was generated by the CASE tools automatically. Our approach was found to realize effective reuse of design and implementation and to enable domain-oriented development in large domains.
