Draw a relational schema for your 3NF relations and show the referential integrity constraints. (5 marks) Notes: · For guidance on how to normalise database relations from a dependency diagram, watch the video How to normalise database relations in 3 quick steps. · Use Draw.io to create your ER Diagrams. · Manually drawing ER Diagrams is NOT acceptable. RATIONALE This assessment task will assess the following learning outcome/s: · be able to analyse a database design and apply normalisation theory and techniques.   MARKING CRITERIA AND STANDARDS Criteria HD DI CR PS FL be able to 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. 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. Analysis identifies key PKs and functional, partial and transitive dependencies. Identifies key 3NF relations, including PKs and relevant attributes and referential integrity constraints. Analysis identifies key PKs and functional dependencies and draws out relevant 3NF relations. Analysis does not identify key PKs or is missing functional dependencies and relevant 3NF relations. PRESENTATION Submit a single .docx, .odt or .pdf file containing your answers. All ER Diagrams need to be embedded into your submitted file.

Dependency Diagram
Third Normal Form
The given database contains multiple dependencies which are n
ot suitable for designing the database. I have divided the given table into 4 tables. Every table has a unique id which is used as the reference in the other tables. All the primary keys are presented using underline and foreign keys are shown in italic form.
The current database is in first normal form as it contains both partial and transitive dependency.
This database stills contains transitive...
