Résumé

The documentation is missing or obsolete, and the original developers have departed. Your team has limited understanding of the system, and unit tests are missing for many, if not all, of the components. When you fix a bug in one place, another bug pops up somewhere else in the system. Long rebuild times make any change difficult. All of these are signs of software that is close to the breaking point.
Many systems can be upgraded or simply thrown away if they no longer serve their purpose. Legacy software, however, is crucial for operations and needs to be continually available and upgraded. How can you reduce the complexity of a legacy system sufficiently so that it can continue to be used and adapted at acceptable cost?
Based on the authors' industrial experiences, this book is a guide on how to reverse engineer legacy systems to understand their problems, and then reengineer those systems to meet new demands. Patterns are used to clarify and explain the process of understanding large code bases, hence transforming them to meet new requirements. The key insight is that the right design and organization of your system is not something that can be evident from the initial requirements alone, but rather as a consequence of understanding how these requirements evolve.

L'auteur - Stéphane Ducasse

Stéphane Ducasse enseigne la programmation objet à l'Institut de mathématiques et d'informatique de l'université de Berne et effectue des recherches sur la programmation objet et la réingénierie. Co-auteur de Object-Oriented Rengineering Patterns chez Morgan Kaufman Publisher, il collabore en tant que relecteur technique avec de nombreux éditeurs américains

Stéphane Ducasse obtained his Ph.D. at the University of Nice-Sophia Antipolis and his habilitation at the University of Paris 6. He was recipient of the SNF 2002 Professeur Boursier Award. He is now a professor at the Université de Savoie. Ducasse has written several books in French and English.

Ducasse's fields of interests include reflective systems design, object-oriented language design, software component composition, application implementation and design, and object-oriented application reengineering. He is the main developer of the Moose reengineering environment. Ducasse also loves programming in Smalltalk and serves as president of the European Smalltalk User Group. He is committed to the Squeak community.
