Object Oriented Design Training in Thimphu, Bhutan

Object-Oriented Design (OOD) training focuses on teaching participants the principles and concepts behind designing software using object-oriented techniques. The course covers key topics such as encapsulation, inheritance, polymorphism, and abstraction, which form the foundation of OOD. Participants learn how to model real-world systems using classes and objects, design flexible and maintainable software, and apply SOLID principles to ensure high-quality code. Hands-on exercises focus on creating class diagrams, identifying relationships between objects, and refactoring designs for better scalability and performance. By the end of the training, attendees will be proficient in applying object-oriented design principles to solve complex software challenges and create well-structured applications.

Advanced Object-Oriented Design and Design Patterns

• Advanced Object-Oriented Design Concepts

• Relationships between classes: Association, Aggregation, and Composition.

• Using composition over inheritance for better flexibility.

• Designing classes that are cohesive and loosely coupled.

• Hands-on Exercise

• Introduction to Design Patterns

• What are design patterns and why are they important?

• Types of design patterns: Creational, Structural, Behavioral.

• Identifying when to apply design patterns in software design.

• Hands-on Exercise

• Creational Patterns
