The assignment involves creating a database system for A&H Boating, which includes designing entity-relationship diagrams (ERDs) to model the organizational processes, boat types, models, warehouses, and customer bookings. The ERDs are used to establish relationships between these entities and to ensure data consistency. This case study presents four ERDs, each representing a different aspect of the A&H Boating database system. Additionally, bibliographic references are provided for further research on database design and normalization.
