Aims
At the completion of this course, the students will be able to:
a) know and understand the core design patterns
b) identify the potential patterns in the design
c) use appropriate design patterns in solving real-world problems
d) build reusable designs and components

5. Behavioral design patterns
5.1. Introduction
5.2. Chain of Responsibility
5.3. Command
5.4. Interpreter
5.5. Iterator
5.6. Mediator
5.7. Memento

Each design pattern description follows the following template: intent, the problem to be solved, the structure (including OMT/UML diagrams), examples (a structural and at least one real-life example).

Lab activities
Three mini-projects, dealing with creational, structural, and behavioral design patterns respectively. Each problem solution will be implemented in two different programming languages (Java, C#, Visual Basic 6.0, Visual Basic .NET, Python, etc).

Course notes and lab material are available on the Win server, in the folder \\win\labor\romana\an3\Design Patterns

Assessment
The final mark will cover lab work (i.e. mini-projects) and the written exam results (last week, in the classroom). It is computed as follows, on a 10-point scale:
1pt by default
1pt seminar/lab attendance
4pts the mini-projects
4pts the written exam
