Design Patterns Training and Certification in Copenhagen, Denmark

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.

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.
