KC7013: Entity Relationship - Computer Science Assignment

Assignment Task:

Part 1 
This part is based on the ‘AiS’ scenario as described in the Appendix.

(A) Using a database design approach of your choice, produce a logical design for the database to support the information system, which is needed at the University of Gharnata.

Your answer must consist of ONE of the following:
An entity-relationship (ER) diagram (20 marks) and its mapping into a set of relations (10 marks). The ER diagram should show all relevant entity types, relationship types, attributes, primary keys, and structural constraints. Note that not all keys are identified/mentioned in the scenario, so you are required to identify/devise appropriate primary keys for all the entity types. Your ER diagram must not show/include any foreign keys or any such attributes that represent foreign keys as these are logical and not conceptual concepts. As part of the mapping process, for each relation, you should identify appropriate primary keys as well as foreign keys (if applicable). Furthermore, you need to make sure your relations obtained from mapping your ER diagram are in the 3rd normal form.
A set of normalized relations (10 marks) obtained through the normalisation process (20 marks) instead of ER modeling. You should make clear how the normalization process has been carried out, and the reasoning employed, in particular quoting/providing evidence (series of steps) to support the decisions made and how your relations have been derived. Each relation in your answer should be in the 3rd normal form.

(B) Based on your logical design from Part 1 (A) and the information available in the scenario, produce an SQL script file using Oracle 11g/12c.
