Software Architecture


About This University Online Course:

The way that software components — subroutines, classes, functions, etc. — are arranged, and the interactions between them, is called architecture. In this course, you will study the ways these architectures are represented, both in UML and other visual tools. We will introduce the most common architectures, their qualities, and tradeoffs. We will talk about how architectures are evaluated, what makes a good architecture, and an architecture can be improved. We’ll also talk about how the architecture touches on the process of software development. In the Capstone Project, you will document a Java-based Android application with UML diagrams and analyze evaluate the application’s architecture using the Architecture Tradeoff Analysis Method (ATAM). After completing this course, you will be able to:

• Compare and contrast the components, connections, protocols, topologies, constraints, tradeoffs, and variations of different types of architectural styles used in the design of applications and systems (e.g., main program and subroutine, object-oriented, interpreters, pipes and filters, database-centric, event-based).

• Describe the properties of layered and n-tier architectures.

• Create UML package, component, and deployment diagrams to express the architectural structure of a system.

• Explain the behaviour of a system using UML activity diagrams.

• Document a multi-application system with a layered architecture.
