Low Level Design → Part 12

Design a simplified, extensible, and testable backend for an online movie-ticketing platform similar to BookMyShow. This article walks through the problem statement, clarification questions, MVP features, domain model, class diagram, schema diagram, and a practical C# implementation blueprint (domain models, repositories, services, and a minimal Web API controller).
