Object-Oriented Analysis and Design with UML and RUP using Rational Software Architect

Overview

Learn how to use object-oriented techniques from requirements gathering to implementation. Students learn how to analyze and design classes and their relationships to each other in order to build a model of the business requirements. A strong emphasis is placed on diagram notation for use cases and class relationships, as well as on sequence and state diagramming to capture the dynamic behavior of the system. Rational Rose is discussed, and examples show how to use the software to create and maintain the various diagrams in the context of the Rational Unified Process.

Audience

This course is intended for anyone involved in the production, deployment and maintenance of software.
