Semester Offering: August
Designing, developing, and evolving complex software systems requires a mastery of analytical and technical skills, as well as a knowledge of appropriate processes, architectures and design patterns. Software architects building complex systems must create the illusion of simplicity through decomposition, abstraction, and encapsulation of functionality.

Software Architecture I and II teach the fundamentals of software architecture, drawn from research and best practice on large software projects. Students will learn techniques and tools for modeling, analyzing, evaluating, and controlling the development of complex software systems.

In Software Architecture Design I, students will develop the basic object-oriented analysis and modeling skills necessary for understanding, designing, and maintaining a software architecture.

Software Architecture I should be taken concurrently with AT70.90C, Selected Topics: Software Development Methodologies.


Software engineering, Software architecture, Object-oriented analysis.


Experience programming in a high-level programming language, e.g. C or Java, or by permission of the instructor.
