Download Use Case Driven Object Modeling with UMLTheory and Practice by Doug Rosenberg, Matt Stephens PDF

By Doug Rosenberg, Matt Stephens

I learnt in regards to the ebook approximately one or years in the past while i used to be looking out the web for whatever like "gap research design". one of many effects was once a four-part sequence approximately "The Iconix technique in pieces". I loved the excerpt and feature used its tricks from time to time. today I needed to research and layout one other fairly advanced software program from scratch. i assumed the e-book might supply me extra important information.

It used to be very fascinating and simple to learn. i locate the Iconix strategy pragmatic and invaluable. The publication comes with a significant portion of conception, plenty of examples of what may possibly get it wrong - which i believe is a really worthy strategy to train the stuff - and with extra exercises.

If you're looking for a entire consultant approximately every kind of UML diagrams or approximately all points of software program structure, this isn't the correct booklet for you.

Example text

So even though this book is about use case–driven development, we have to begin at the beginning with domain modeling. What’s a Domain Model? As just mentioned, a domain model is, essentially, a project glossary: a “live” dictionary of all the terms used in your project. But a domain model is better than a project glossary, because it shows graphically how all these different terms relate to each other. In practice it’s a simplified class diagram, with lines drawn between the different classes (domain objects) to show how they relate to each other.

The bookstore must be able to accommodate up to 100 search requests per minute (1,000/minute after six months). d. The bookstore must be able to accommodate up to 100 purchases per hour (1,000/hour after six months). These requirements are a rich source of domain classes. qxd 32 12/13/06 8:28 PM Page 32 CHAPTER 2 ■ DOMAIN MODELING There’s quite a bit of duplication in this list; similar terms are being used for basically the same thing. But that’s really the main benefit of the domain modeling approach: you get to identify and eliminate these duplicate terms early on in the project.

8. Expect to rewrite (disambiguate) your use case while drawing the robustness diagram. 7. Make a boundary object for each screen, and name your screens unambiguously. 6. Remember that controllers are only occasionally real control objects; they are typically logical software functions. 5. Don’t worry about the direction of the arrows on a robustness diagram. 4. It’s OK to drag a use case onto a robustness diagram if it’s invoked from the parent use case. 3. The robustness diagram represents a preliminary conceptual design of a use case, not a literal detailed design.
