Task Summary
In this assessment, you are required to perform database table normalisation and present your solutions in a PowerPoint presentation. In doing so, you are required to demonstrate your work and solution through a series of normal forms. You need to first normalise the database tables to the first normal form (1NF), then the second normal form (2NF), and finally the third normal form (3NF).
Context
In the first two modules, you learnt data models and relational data modelling. Next, you were introduced to the database table normalisation process in Module 3.1, which is aimed to enhance the quality of database tables. Normalisation plays a significant role in ensuring database tables are well structured so that both data redundancies and the likelihood of data anomalies can be minimised.
By completing this assessment, you will demonstrate your understanding of the following:
(1) the database table normalisation process and
(2) the criteria for database tables to be in 1NF, 2NF and 3NF as well as your ability to:
(1) comprehend business rules and logic to determine data dependencies,
(2) perform database table normalisation process and normalise database tables up to 3NF and
(3) articulate your solutions and the rationale to an audience.

2. Please complete the following tasks and deliver a 5-minute presentation to communicate your answers/solutions to an audience.
Task 1 (15 marks)
Draw and present a dependency diagram for the table above, including transitive dependencies. In your oral presentation, you need to explain each dependency.
Task 2 (5 marks)
If the table above is not in the first normal form, normalise it so that it is in the first normal form without creating any more tables. You may create an additional attribute or attributes. Orally present your solution and the reason why it was not in the first normal form, and what changes were made to make it in the first normal form. If the table above is in the first normal form, explain why it is in first normal form.
Task 3 (15 marks)
If the resulting table from the previous task is not in the second normal form, normalise it so that it is in the second normal form without creating any more tables. You may create an additional attribute or attributes. Orally present your solution and the reason why it was not in the second normal form, as well as the changes that were made to turn it to the second normal form. If the resulting table from the previous task is already in the second normal form, explain why it is in the second normal form.
Task 4 (30 marks)
If the resulting table from the previous task is not in the third normal form, normalise it so that it is in the third normal form. You may create additional tables. Orally present your solution and the reason why it was not in the third normal form, as well as the changes that were made to turn it to the third normal form. If the resulting table from the previous task is already in the third normal form, explain why it is in the third normal form.
Task 5 (15 marks)
Based on the resulting table from the previous task, draw and present an ERD to the audience. Please use LucidChart or an equivalent professional diagramming software application to draw the
ERD.
3. When completing this assessment, you are required to make reasonable assumptions based on common sense. For example, the following are considered as common sense or reasonable assumptions:
• Two persons may have the same name, that is, the same first name AND same last name.
• Two persons who were born on the same day may have the same name.
• A student will undertake more than one subject at a university.
• More than one subject may be taught by one lecturer.
• Each subject has only one subject name.
• Each School only has one Head of School.
Length and Layout of the Presentation
• The total presentation should be no more than 10 minutes. This includes a 5-minute question-and-answer session.
• Please prepare your presentation using Microsoft PowerPoint.
Submission Instructions
Please submit ONE PowerPoint Presentation (.ppt or .pptx) via the Assessment 2 section found in the main navigation menu of the subject’s Blackboard site. The Learning Facilitator will provide feedback via the Grade Centre in the LMS portal. Feedback can be viewed in My Grades.
