OOAD's increasing popularity is brought about in part because of its ability to represent complex relationships, as well as data and data processing, with a consistent notation.
You will be introduced to several techniques that systems analysts can use to perform object-oriented analysis and design. The techniques and notations presented in this chapter include use cases, class diagrams, object diagrams, state diagrams, and sequence diagrams.
The Unified Modeling Language (UML) is used to present these techniques and notations. The object-oriented development life cycle consists of three primary phases: analysis, design, and implementation.
