Database Design of A&H Boating

This assignment involves designing a database for A&H Boating, which includes creating entity relationship diagrams (ERDs) and describing the attributes of various entities. The ERD shows the relationships between different tables in the database, including A&HBoating, Manufacturer_Details, BoatDetails, ModelDetails, Warehouse_Details, and Customer_Details. The data description provides details about each attribute, such as its type, whether it is null or not, and its value length.
