The course introduces core concepts and principles of software architecture, focusing on software architecture definition(s), architectural styles and models, architecture definition languages, and tool support for architectural design. All theoretical concepts are introduced by case studies, taken from real applications.

Lab activities

At least two design solutions for the problems introduced in the course lectures, using different architectural styles. Every design solution will be implemented in at least two different programming languages (Java, C#, Visual Basic 6.0, Visual Basic .NET).

The final mark covers lab activity and written exam. It is computed as follows, on a 10-point scale:
1pt by default
1pt lab attendance
4pt lab activity (homework, implementation issues, schedule conformance etc.)
4pt written exam - scheduled in the last week of the term.
