UML

Object orientation has become the predominant paradigm for virtually all modern software development. This course builds on basic concepts to apply object-oriented principles to all phases of the software development life cycle, with particular emphasis on analysis and design. Students will participate in case studies and short exercises. The Unified Modeling Language (UML) is introduced and is used as the common language in all examples and exercises.

Audience

This course is intended for software developers, programmers, and analysts who are familiar with, and experienced in, software development methodologies who will be using object orientation and UML in upcoming projects.

Prerequisites

The students must have experience in software development and familiarity with object orientation concepts. It is recommended that the students take an Object Orientation Overview course or has equivalent experience.
