Chat Application Low-Level Design (LLD) | System Design

💬 *Chat Application Low-Level Design (LLD) | System Design | Object-Oriented Design* In this video, we explore the Low-Level Design (LLD) of a Chat Application, focusing on the core components, functional requirements, and object-oriented design principles needed to build a scalable, real-time messaging system. *📌 Topics Covered:* Overview of a Chat Application Functional Requirements: One-to-one messaging, group chats, chat history, and ordered message delivery Non-Functional Requirements: Modularity, scalability, low latency, and extensibility Core Entities: User, Message, Chat, and ChatService Responsibilities of each component and how they interact Designing for future enhancements like file sharing and message reactions This video is useful for software engineers preparing for **Low-Level Design (LLD), Object-Oriented Design (OOD), and System Design interviews**.
