Task2. Decompose the relation into a set of 3NF relations 3. Draw a relational schema for your 3NF relations and show the referential integrity constraints 4. Create an ERD that represents your 3NF relations NOTE For guidance on how to normalise database relations from a dependency diagram, or the set of 3NF relations or the relational schema or the ERD is NOT acceptable. Rationale This assessment aligns with the following subject outcomes: be able to critically analyse a database design and apply normalisation theory and techniques; Marking criteria Each task is worth 3.25 marks. The marking criteria for this assignment is: Criteria HD DI CR PS be able to critically analyse a database design and apply normalisation theory and techniques; Analysis identifies all PKs and functional, partial and transitive dependencies. Accurately identifies all 3NF relations, including PKs, relevant attributes and referential integrity constraints. Creates an ERD that represents all 3NF relations and includes all entities, PKs, attributes, relationships, associative entities (if applicable), cardinalities and optionalities. Analysis identifies PKs and functional, partial and transitive dependencies with minor omissions. Accurately identifies 3NF relations, including PKs, relevant attributes and referential integrity constraints with minor omissions. Creates an ERD that represents identified 3NF relations and includes all entities, PKs, attributes, relationships, associative entities (if applicable), cardinalities and optionalities. Analysis identifies key PKs and functional, partial and transitive dependencies. Identifies key 3NF relations, including PKs and relevant attributes and referential integrity constraints. Creates an ERD that represents identified 3NF relations and includes the related entities, PKs, attributes, relationships, associative entities (if applicable), cardinalities and optionalities. Analysis identifies key PKs and functional dependencies and draws out relevant 3NF relations. Creates an ERD that represents identified 3NF relations and includes the related entities, PKs, attributes, relationships, cardinalities and optionalities.
