Create a database design specification (Enhanced Entity Relationship Diagram (EERD) and Relational Data Model (RDM)) from the given business description. The RDM must be in 3rd Normal Form.
The following defines the minimum information that should be reported:
• List and explain the defined business rules that can be determined from the business description.
• The Enhanced Entity Relationship Diagram (EERD) produced with a drawing or case tool. Your EERD must use a 'standard' notation style such as Crows Foot or Chen. Please note that the relationship diagram produced using MS Access, or MS SQL Server is NOT an acceptable ERD notation. Your EERD must show:
o All entities,
o Primary and Foreign keys, as appropriate,
o All attributes for each entity,
o Relationships between entities, including their cardinality and optionality,
o The EERD must not contain any M:N relationships. These must be decomposed.
• The Relational Data Model (RDM) which corresponds to the ERD in the format shown below. The RDM MUST identify all primary keys, alternate keys and foreign key constraints. Raw SQL Create Table script dumps from a modeling tool, or SQL Server WILL NOT be accepted.
• The RDM must be in 3rd Normal Form.
• The assumptions that you have made to develop the system.
