Accоrding tо the fоllowing dаtаbаse requirements: The hotel‑reservation database is a relational data model that stores the core entities — Customers, Operators, Room Categories (Single, Double, Suite), individual Rooms, Reservations, Payments, Refunds, and Check‑In and Out logs. Customers must register (unique email, hashed password) before they can create a reservation, which records the requested category, stay dates (check-in and out dates), guest count, total price and links to a captured credit/debit‑card payment. Room Category defines the three-room types and their base rates; each physical Room is linked to a category and has a status (available, occupied, out‑of‑Service). When a reservation is confirmed, the system ensures that at least one room of the chosen category is free for the entire period. Front‑desk Operators perform check‑in by assigning a concrete Room ID and logging the actual check‑in time; check‑out is recorded when the guest notifies the hotel. A reservation can be cancelled only if the request occurs ≥ 24 hours before the scheduled check‑in; a database trigger enforces this rule and automatically creates a Refund entry that references the original Payment, resulting in a full credit‑card refund.
