Object Oriented Requirements Analysis

In this unit, we will begin discussing object oriented techniques for analysis and design.  The modeling mechanisms and syntax are fully defined in the Unified Modeling Language (UML) standards, which have their origins in object oriented software systems design.  Although they were originally intended as a tool for software development, their usefulness and flexibility for modeling any digital infrastructure have facilitated their becoming the defacto standard models used in systems analysis and design as well.

In this unit, we begin with Use Case models, which are similar to the context level diagrams we covered in the previous unit.
