Description

Description

This course provides a deep dive into object-oriented design patterns—essential tools for developing high-quality, maintainable software systems that meet requirements and ship on time. Geared towards developers and architects, the course blends formal design principles with real-world application, giving you both the conceptual foundation and the practical skills needed to build robust, reusable systems.

Focusing primarily on the well-known Gang of Four (GoF) design patterns, the course explores the most important patterns across Creational, Structural, and Behavioral categories. You’ll also get exposure to additional patterns, including Dependency Injection (DI) and common Enterprise Architecture Patterns.

While course examples are presented in Java, coding is not required during the labs. Instead, labs are hands-on and conceptual, focused on design thinking and applying patterns in practice through structured design exercises and projects.

Note: Java experience is helpful, but the focus is on design—not language-specific syntax.

Training Objectives

• By the end of this course you will:
• Understand key object-oriented design pattern concepts and terminology
• Apply patterns to design flexible scalable and maintainable software
• Gain fluency with the most common GoF design patterns
• Know when and how to use Creational Structural and Behavioral patterns
• Understand key enterprise and architectural patterns
• Design systems that reduce code duplication and improve modularity
• Communicate effectively using the shared vocabulary of design patterns
