What is System Design?

System design is the process of defining the architecture, components, modules, and interfaces of a system along with data based on specific requirements. It involves identifying, developing, and designing systems to meet the aims and expectations of an organization. System design focuses on system analysis, architectural patterns, APIs, design patterns, and integration to provide a better user experience and reduce maintenance costs. System design concepts, such as scalability, load balancing, and caching, are crucial for tech interviews at product-based companies like Facebook, Amazon, and Google.

Software Design and Architecture Specialization by University of Alberta

The Software Design and Architecture Specialization teaches you how to use design ideas, patterns, and architectures to create reusable and flexible software. You’ll learn to use visual notation, like the UML, to express and document the design and architecture of a software system.

This specialization has four courses, including Object-Oriented Design, Design patterns, Software Architecture, and Service-Oriented Architecture.

The first course teaches you how to construct modular, adaptable, and reusable software using object-oriented design with Java programming language. You’ll also learn to use UML to communicate your designs.

The second course builds upon the first by introducing design patterns for interactive applications, and identifying bad software designs.

The third course focuses on modeling complex architectures using UML and other visual tools. You’ll learn about prevalent architectures, their benefits and drawbacks, what makes good architecture, and how to enhance architecture.

The fourth course covers analyzing web application designs based on your understanding of architectural styles and the basics of Service-Oriented Architecture (SOA), such as Web Services (WS*) and Representational State Transfer (REST) architecture.

Associate Professor Kenny Wong teaches this course for beginner-level coders with basic Java programming language knowledge. The specialization comprises four courses and takes approximately four months to complete with a suggested pace of three hours per week.
