On the Co-Evolution of SSADM and the UML

Abstract

This chapter examines how a system developed using the Structured Systems Analysis and Design Methodology (SSADM) evolves to fit the UML and XML. As a vehicle, the chapter will consider the addition of a new user story to an existing SSADM system. SSADM developed in the early 1980’s. It is still popular. It is similar to other Structured Analysis and Design methods. Evolving SSADM to use the UML and XML is important. This chapter argues that XML is an opportunity, not a problem. It also shows that the earlier UMLs did not support SSADM but the new UML 2.0 does.
