Task Summary
This assessment requires you to prepare a modelling report that demonstrates your ability to
assess business requirements along with a logical design that could be implemented in a
relational database management system.
Context
When preparing to implement a new information system, it is essential that the initial design
is well thought out from the outset. Modifying the database after implementation can often
be an expensive process in terms of time, effort and cost. Often the first engagement step is
to conduct interviews and workshops with end users and business subject matter experts to
get a better understand of how the business runs. The output of these workshops becomes
the foundation for the database design.

Task Instructions
Please read the attached MIS602_Assessment 1_Case Study.
Based on the information provided in the case study, prepare a modelling report to answer
the following tasks:
Task 1: An entity relationship diagram including all the significant entities, attributes
and their relationships. Use Crow’s foot notation.
Task 2: A relational model showing all fields, primary keys, foreign keys and
concatenated keys. Your relational model should be in third normal form. List any
assumptions/business rules you have made.
Task 3: A sample dummy input screen of scheduling an interview for one of the
shortlisted candidates. You have to make sure all the data requirements are being
captured.
You may use any tool you like to create this sample screen. Write a brief paragraph
of about 200 words discussing the following:
Does your database design allow the storage of all the required
information?
What changes, if any, did you make to your initial ER diagram and relational
model after you created the sample input screen?
The front-end or user interface design enables accessing the data stored in a database.
Prototyping the interface also enables capturing initial system and data requirements.
Submission Instructions
Please compile all the three tasks into a single word document and submit via the Assessment
1 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.
Academic Integrity

When submitting their assessment task, students will be asked to declare the academic
integrity of their assessment by completing and signing an assignment cover sheet. You can
find the assignment cover sheet here

All students are responsible for ensuring that all work submitted is their own and is
appropriately referenced and academically written according to the Academic Writing Guide.

Assessment 1, MIS602 Page 3 of 4
Students also need to have read and be aware of Torrens University Australia Academic
Integrity Policy and Procedure and subsequent penalties for academic misconduct. These are
available at
https://www.torrens.edu.au/policies-and-forms.
Students also must keep a copy of all submitted material and any assessment drafts.
Special Consideration
To apply for special consideration for a modification to an assessment or exam due to
unexpected or extenuating circumstances, please consult the Assessment Policy for Higher
Education Coursework and ELICOS and, if applicable to your circumstance, submit a
completed Application for Assessment Special Consideration Form to your Learning
Facilitator. These documents are available at
