Scaling my FastAPI Movie Booking API to a real reservation system, step-by-step. Previously, the database relied on a single flat Movie table to track showtimes and decrement raw seat counts. It worked for a simple catalog, but lacked a transactional audit trail. To transition toward a "BookMyShow" style architecture, I've evolved the schema into a three-table relational design: 1️⃣ User: For secure credentials and profile management. 2️⃣ Movie: Retaining metadata, showtimes, and total capacity. 3️⃣ Booking: The core bridge tracking exactly who reserved which show, when, and how many seats. This establishes the proper relational foundation and ensures bookings have an audit history. Next up on the roadmap: 🔑 Implementing JWT authentication to secure the write endpoints. 🔒 Adding transaction-level locking to manage concurrent seat selections safely.
