Course Overview
The LLD course spans five weeks, combining theoretical concepts with practical exercises. It is designed to cater to both beginners and experienced professionals seeking to strengthen their system design skills. The course emphasizes
- Understanding core object-oriented principles
- Mastering design patterns and their applications
- Developing proficiency in UML diagrams and system architecture
- Implementing real-world system design examples
- Preparing for system design interviews with mock sessions and feedback
Curriculum Breakdown
Week 1 Object-Oriented Principles and Design Patterns
The first week introduces fundamental object-oriented concepts such as classes, objects, inheritance, and polymorphism. Students delve into essential design principles like SOLID, DRY, and KISS, which form the foundation for writing clean and maintainable code. The week also covers
- Factory and Abstract Factory design patterns
- UML class diagrams for visualizing system components
Week 2 Creational and Behavioral Design Patterns
Building upon the previous week, this session focuses on creational and behavioral design patterns, including
- Singleton, Builder, and Prototype patterns
- Observer, Command, Chain of Responsibility, and Iterator patterns
Students learn how to apply these patterns to solve common design challenges and enhance system flexibility.
Week 3 Structural Design Patterns
This week covers structural design patterns that help in organizing classes and objects to form larger structures. Topics include
- Adapter, Decorator, Bridge, Composite, Proxy, and Facade patterns
Emphasis is placed on recognizing scenarios where each pattern is applicable and understanding their impact on system architecture.
Week 4 Real-World System Design Examples
Students apply their knowledge to design real-world systems, such as
- IRCTC (Indian Railway Catering and Tourism Corporation)
- Chess game architecture
- Elevator system design
These case studies provide practical insights into translating requirements into scalable and efficient system designs.
Week 5 Revision and Interview Preparation
The final week focuses on consolidating learning and preparing for interviews. Activities include
- Designing a recommendation system
- Creating a meeting scheduler application
- Participating in mock interviews and receiving constructive feedback
Students also review key concepts and design patterns to reinforce their understanding.
Learning Approach
Keerti Purswani employs a hands-on, interactive teaching methodology that includes
- Live coding sessions and demonstrations
- Assignments and quizzes to reinforce learning
- Access to a community forum for peer discussions and support
