CSE2DBF Assignment 1 – ER/EER Model

AIMS AND OBJECTIVES:

to convert the ER/EER model into a relational data model;
to implement a relational database system (using Oracle APEX).

This is an individual Assignment. You are not permitted to work as a group when writing this
assignment.

Copying, Plagiarism: Plagiarism is the submission of somebody else’s work in a manner that gives
the impression that the work is your own. The Department of Computer Science and Information
Technology treats plagiarism very seriously. When it is detected, penalties are strictly imposed.
No extensions will be given: Penalties are applied to late assignments (5% of total assignment mark
given is deducted per day, accepted up to 5 days after the due date only). If there are circumstances
that prevent the assignment being submitted on time, an application for extension may be made. See
Student Handbook for details. Note that delays caused by computer downtime cannot be accepted as a
valid reason for a late submission without penalty. Students must plan their work to allow for both
scheduled and unscheduled downtime.

SUBMISSION GUIDELINES:

This assignment is to be submitted in soft-copy (one PDF file for Task 1, one .txt/.sql file
for Task 2) formats using the CSE2DBF submission link on LMS by 11:59 pm Monday
September 20th, 2021. The submission link can be found under “Assignment 1 – Part 2”under the “Assessments” section of your subject LMS page.

SUBMISSION CHECKLIST:

The transformation steps from your EER Model (Appendix A) to your final tables (Task 1); Make
sure to show each step of the transformation, and the final transformation tables;
The DDL implementation for the ‘Dealership Database System’ tables from Task 1 (create table
statements), and the required insert statements (Task 2a and 2b respectively).
Students are referred to the Department of Computer Science and Information Technology’s
Handbook and policy documents with regard to plagiarism and assignment return, and also to the
section of ‘Academic Integrity’ on the subject learning guide.

TASKS:

1. Transform the EER model (Appendix A) to Relational tables, making sure you show all the
steps. The final set of tables should contain necessary information such as table names,
attribute names, primary keys (underlined) and foreign keys (in italics).

[60%]
2. a) Write create table statements to implement the tables in the ORACLE Relational DBMS.
When creating tables make sure you choose appropriate data types for the attributes,
specify any null/not null or other constraints whenever applicable, and specify the
primary and foreign keys.
b) Write at least one insert statement for each of your tables using realistic data. Make sure
you take into consideration all the necessary constraints.

[40%]

Submission note: You are required to submit two documents:
1. a PDF file with the answers for Task 1, where you clearly show all the relevant
transformation steps for the given EER model.
2. a text file (.txt) or an SQL file (.sql) for Task 2, where you have all the create table statements
and insert statements.
