Duration 3 days – 21 hrs
Overview
The Overview on Design Pattern Training Course provides a foundational understanding of software design patterns proven solutions to common problems in software design. This course introduces participants to object-oriented design principles and the most widely used design patterns, helping developers write clean, reusable, and maintainable code. Through real-world examples and practical exercises, participants will learn how to recognize design problems and apply appropriate design patterns to solve them effectively.
Objectives
- Understand the purpose and benefits of using design patterns in software development.
- Identify different types of design patterns: Creational, Structural, and Behavioral.
- Apply appropriate design patterns to solve common software design challenges.
- Improve code reusability, scalability, and maintainability.
- Recognize anti-patterns and avoid common design pitfalls.
- Understand how design patterns are implemented in popular programming languages like Java, C#, or Python.
Audience
- Software Developers and Engineers
- System Architects and Technical Leads
- Application Designers
- Software QA and Test Automation Engineers
- Anyone interested in improving software architecture and design skills
Prerequisites
- Basic programming knowledge in any object-oriented language (e.g., Java, C#, Python, or C++)
