CHAPTER 14
THE MOVEMENT TO OBJECTS
The field of systems analysis and design now incorporates object-oriented concepts and techniques, by which a system is viewed as a collection of self-contained objects that include both data and processes. Objects can be built as individual pieces and then put together to form a system, leading to modular, reusable project components. In 1997, the Unified Modeling Language (UML) was accepted as the standard language for object development. This chapter describes the four most effective UML models: the use case diagram, class diagram, sequence diagram, and behavioral state machine diagram.
OBJECTIVES
- Understand basic concepts of the object approach and UML.
- Be able to create a use case diagram.
- Be able to create a class diagram.
- Be able to create a sequence diagram.
- Be able to create a behavioral state machine diagram.
