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.

NOTE - For guidance on how to normalise database relations from a dependency diagram, watch this very short YouTube video: https://www.youtube.com/watch?v=vkUyuLLgmwQ. Manually drawing the dependency diagram, or the set of 3NF relations or the relational schema or the ERD is NOT acceptable. Requirements - Either save your diagrams in a PDF file or embed them in a Word document. Don't use any other file formats. Please include your student ID, name and subject code in your submission. Submission Method: Turnitin. Details will be provided by the lecturer during the session.
