The Application of Object-Oriented Design Techniques to the Evolution of the Architecture of a Large Legacy Software System
Jeff Mason and Emil S. Ochotta, Xilinx Inc.
Abstract
Object Oriented Analysis and Design (OOAD) is increasingly popular as a set of
techniques that can be used to initially analyze and design software.
Unfortunately, OOAD is a relatively new concept and many large legacy systems
predate it. This paper presents the approach one company followed in applying
OOAD techniques to an existing 2.5 million line code base. We present an
iterative process that provides an avenue for the software to evolve while
balancing the needs of business and software engineering. Our case study reveals
the many pitfalls that can derail a software re-engineering effort, but also
shows promising initial results from continued perseverance in this effort.
