This repository contains examples of Low-Level Design (LLD) implemented in Python. LLD focuses on the detailed design of individual components of a system, including class design, data structures, algorithms, and module-level architecture.
Understanding LLD is crucial for building robust, maintainable, and scalable software. These examples aim to illustrate key LLD principles and patterns through practical implementations.
- Movie Booking System: A detailed example demonstrating the LLD of a simple movie booking system, including classes for movies, cinemas, shows, seats, bookings, and users.
Before diving into the LLD examples, it's beneficial to have a grasp of the following general topics:
- Object-Oriented Programming (OOP) Principles: Encapsulation, Inheritance, Polymorphism, Abstraction.
- UML Diagrams: Class diagrams and sequence diagrams for visualizing design.
- Design Patterns: Common solutions to recurring design problems (e.g., Singleton, Factory, Observer).
- Data Structures and Algorithms: Choosing appropriate structures and algorithms for efficiency.
- Code Modularity and Reusability: Designing components that are independent and reusable.
- Error Handling and Exception Management: Strategies for dealing with errors gracefully.
- Testing: Writing unit tests and integration tests to ensure correctness.
- Code Style and Best Practices: Writing clean, readable, and maintainable code (e.g., PEP 8 for Python).
