Hotel Management System

This C# and SQL project implements a hotel management system backed by a relational data model. Its database work includes both the schema for the new application and a migration from an existing legacy system.

The entity-relationship diagram documents the principal records and their relationships, while the initial creation script shows how that model is represented in SQL. The migration requirement adds a practical data-management concern beyond implementing the application itself: existing operational information must be carried into the replacement structure safely and consistently.
