Design patterns training introduces participants to reusable solutions for common software design problems, helping them improve code structure and maintainability. The course covers key design patterns, such as Singleton, Factory, Observer, and Strategy, along with their practical applications in real-world scenarios. Participants learn to identify the right pattern for specific problems, enhance code reusability, and ensure flexible and scalable software architecture. Hands-on exercises focus on implementing design patterns in various programming languages and frameworks, reinforcing their understanding and application. By the end of the training, attendees will be able to apply design patterns effectively to create efficient and robust software solutions.

Basic knowledge of object-oriented programming (OOP).
Familiarity with fundamental programming concepts like classes, objects, inheritance, and polymorphism.
Experience in any object-oriented programming language (Java, C#, Python, etc.).

Upon completion of this course, participants will:

Understand the fundamental concept of design patterns and their importance in software development.
Learn the classification of design patterns and when to use them.
Gain practical experience in implementing design patterns in real-world scenarios.
Understand the benefits of design patterns, including reusability, maintainability, and scalability.
Be equipped to select and apply appropriate design patterns in various problem domains.

Understanding Design Patterns: Knowledge of different types of design patterns, including creational, structural, and behavioral patterns.
Design Pattern Classification: Ability to classify and choose appropriate design patterns for various design problems.
Pattern Implementation: Skill in implementing common design patterns in software projects.
Problem-Solving with Design Patterns: Ability to recognize design problems and select the correct pattern to solve them.
Improved Code Quality: Knowledge of how design patterns contribute to clean, maintainable, and scalable code.

Participants will be assessed on:

Pattern Classification: Ability to identify which category (creational, structural, or behavioral) a given design pattern belongs to.
Pattern Application: Practical knowledge in applying patterns to real-world scenarios.
Pattern Implementation: Ability to implement patterns such as Singleton, Factory, Observer, and others in code.
Problem-Solving with Patterns: Demonstrating the use of design patterns to solve common software design problems.

Certificate of Completion: Participants who attend all sessions and successfully complete the course assessments will receive a ProgNXT Certificate of Completion for Design Patterns Training.

Introduction to Design Patterns and Creational Patterns

Introduction to Design Patterns

What are design patterns and why are they important in software development?
Benefits of using design patterns: maintainability, flexibility, and scalability.
Overview of the three categories of design patterns: Creational, Structural, and Behavioral.
The role of design patterns in object-oriented design and software engineering.
Hands-on Exercise

Creational Design Patterns

Understanding the purpose of creational patterns: controlling object creation.
Overview of the most common creational patterns:

Singleton Pattern: Ensuring a class has only one instance.
Factory Method Pattern: Defining an interface for creating objects but letting subclasses decide which class to instantiate.
Abstract Factory Pattern: Creating families of related objects without specifying their concrete classes.
Builder Pattern: Constructing complex objects step by step.
Prototype Pattern: Creating objects based on a prototype instance.

Hands-on Exercise

Practical Applications of Creational Patterns

When to use each creational pattern in real-world scenarios.
Pros and cons of each pattern.
Examples from industry practices.
Hands-on Exercise

Summary and Q&A

Recap of key concepts.
Q&A session to address challenges and doubts faced during exercises.

Structural and Behavioural Design Patterns

Structural Design Patterns

Understanding the purpose of structural patterns: organizing and simplifying object relationships.
Overview of key structural patterns:

Adapter Pattern: Converting one interface to another to be compatible with the client.
Composite Pattern: Composing objects into tree-like structures to represent part-whole hierarchies.
Decorator Pattern: Attaching additional responsibilities to an object dynamically.
Facade Pattern: Providing a simplified interface to a complex subsystem.
Proxy Pattern: Controlling access to an object by acting as an intermediary.

Hands-on Exercise

Behavioral Design Patterns

Understanding the purpose of behavioral patterns: improving communication and responsibility delegation between objects.
Overview of key behavioral patterns:

Observer Pattern: Defining a one-to-many dependency between objects.
Strategy Pattern: Defining a family of algorithms and making them interchangeable.
Command Pattern: Encapsulating a request as an object.
State Pattern: Allowing an object to alter its behavior when its internal state changes.
Template Method Pattern: Defining the skeleton of an algorithm, deferring some steps to subclasses.

Hands-on Exercise

Practical Applications of Structural and Behavioral Patterns

When to use each structural and behavioral pattern in real-world scenarios.
Exploring trade-offs and challenges when implementing these patterns.
Hands-on Exercise

Summary and Q&A

Recap of key concepts.
Q&A session to address challenges faced during exercises.

Slides and documentation on each design pattern.
Sample code for each design pattern implementation.
Cheat sheets for identifying and applying design patterns.

Evaluation based on participation in practical exercises, the quality of design pattern implementations, and the ability to correctly apply patterns to problem scenarios.
ProgNXT Certificate of Completion will be awarded to participants who successfully complete the course and assessments.

This Design Patterns Training will enable participants to develop a solid understanding of the most common design patterns in software engineering. By the end of the course, participants will have hands-on experience in applying creational, structural, and behavioral design patterns to real-world problems, improving the maintainability, scalability, and flexibility of their software projects.
