Description:
After a quick introduction to the design process Catalysis, this book moves on to carefully defining objects, their attributes, operations, and collaborations. (Generally, Catalysis objects and components are "decoupled" so that they can work more independently, leading to easier reuse and customization.) The authors then turn to modeling and design, using a spreadsheet program as their example. Next, the authors discuss component-based design, where projects are assembled with components. The book closes with an effective tour of the actual Catalysis design process, illustrated with a case study for a video-rental store. All design documents, written in the Unified Modeling Language (UML), are provided along with some useful expert advice on creating better design documents and components. Judging from the evidence here, the Catalysis design method can offer some real advantages for today's software, which often must evolve to meet unforeseen requirements (international markets or new platforms such as the Web). Designed according to the principles outlined in the book, components and designs can offer a higher level of reuse. Even if you do not actually adopt the Catalysis process, this authoritative and admirably clear book offers a wealth of design expertise for anyone interested in being more productive with objects and UML. --Richard Dragan
