Presents a risk-managed approach to legacy system modernization that combines a knowledge of software technologies and an understanding of engineering processes within a business context. A case study illustrates the transformation of a large supply chain system written in Cobol to a modern system based on the Java 2 enterprise edition (J2EE) architecture. The authors (Software Engineering Institute) use the unified modeling language to represent architecture drawings and design patterns.
