Catalog Description

The course focuses on design patterns, patterns for concurrent software systems, antipatterns and recognizing design problems, refactoring bad design to patterns. Hands-on experience on reuse of design patterns will be established by a class project. The course includes reviews of UML, object-oriented design and aspect oriented design. Students will be able to efficiently communicate program structures using patterns and to develop software of high quality.

Course Purpose

The aim of this course is to make the students competent in designing effective and maintainable complex software systems of high quality. To this end, students will learn and gain hands-on experience in designing software systems by reusing/applying design patterns. Design patterns are successful solutions to recurring problems that arise when building software systems. Reusing design patterns helps to prevent subtle issues that can cause major problems and improves code readability for the developers familiar with the patterns. In addition to mastering these good design abstractions, the students will also learn how to evaluate a design, identify common problems, and how to fix these problems through refactoring.
