1 IFB105 Database Management Project – part A Project overview The IFB105 project gives you an opportunity to apply concepts and skills you acquired in the unit to a realistic database design scenario and reflect on the data requirements of an organisation. The submission is divided into 2 parts due at different times during the semester. These parts will cover: A. Design of a database B. Creation and use of a database The task for part A In this part, you will: 1. Design an ORM conceptual schema for a business domain based on sample reports required for that domain. 2. Map a different ORM schema to a relational database schema. Weighting Part A is worth 15 marks, for 15% of the unit. Groups This assignment can be done individually or in pairs. If you choose to work in a pair, only one student should submit the assignment. Please provide the name and student number of the person you worked with on the front page. No consideration will be given to any student who claims to have done more work than the other student in his/her pair, because this assignment can be done individually. Doing the assignment in undeclared groups, or groups larger than two students, will be treated as plagiarism. Pairs that work together and then split due to difficulties must not submit any of the same work, or it will be treated as plagiarism. Due date Tuesday September 3 at 11:59 pm (start of week 7). Submission For this assessment, you should submit a professionally presented Word document containing your solution to each task. For Task 1, ORM schemas should be created using a computer drawing program, such as Lucid Chart or draw.io. For Task 2, the relational schema must be entered using either the horizontal notation taught in lectures and tutorials. You should annotate the basic relational schema to ensure all the ORM constraints and subtype definitions are captured. Partial or fully handwritten submissions will not be accepted. Your document needs to be uploaded to the submission link on Blackboard. Late submission Assessment work submitted after the due date will be marked only with an approved extension (MOPP E/6.8.2). Assessment work submitted after the due date without an approved extension or, where an extension has been granted, after the extended due date, will not be marked and a grade of 1 or 0% will be awarded against the assessment item. Please note: extensions will not be granted for group (2 members) submissions, regardless of the reason.
