Submit …………………… PDF Document via Blackboard
Rationale and Description
Foundational to addressing business concerns is an understanding of core concepts, principles and skills required for understanding, designing, and managing databases. This implies understanding the kinds of techniques that are used to model data, and an ability to develop a concise conceptual model that represents a given universe of discourse.
This assessment will involve creating a conceptual schema design for a given universe of discourse and the generation of a relational mapping.
You will use your knowledge from the lectures and the techniques practised in the tutorial sessions and apply both to a set of tasks that refer to some business concern. You will not only perform the necessary steps to solve the tasks, but also provide an explanation of your approach.
Learning Outcomes
A successful completion of this task will demonstrate:
1. Knowledge of conceptual data modelling principles to understand, capture and analyse an abstraction of the complex data aspect of business domains.
2. Develop rigorous database design underpinned by a conceptual data model
Instructions
This assessment will have a Group task with Individual components. You will have to solve two tasks:
1. Apply the Conceptual Schema Design Process (steps 1 – 6) to a given business concern (group task)
2. Map a conceptual schema design to a relational database schema (individual task)
For task 1, you can use any modelling tool (including MS PowerPoint, LucidChart, or even handwriting) to draw your models. Make sure the diagrams are readable. Assignment submissions are to be made via IFN554 Blackboard (including submission for formative feedback).
Groups should be of 2 members (exceptions can be made with the approval of the teaching team). Group members should belong to the same tutorial group.
Assignment submissions MUST be a single PDF file properly identified (student name and number).
Feedback
Feedback will be provided on specific questions related to the assessment during the drop-in session times, and via MS Teams. Please note that the teaching team will NOT respond to general “is this good enough” style questions or requests to pre-assess your work.
Submission of assessment
All assessment will be submitted via standard QUT electronic submission methods (e.g. Blackboard, Turnitin), and you will need to submit your assessment in the format specified in the assessment task sheet. Assessment will not be accepted by any other method or in any other format. Please note that all assessment is due on a Tuesday 19th April 11:59pm. You should submit early to avoid delays from technical issues. The most recent assessment prior to the due date will be used for marking. Please ensure that you are aware of QUT’s policy on late assignments:
Late Submission – requesting an extension
No member of the teaching team, including the unit coordinator, can grant you an extension for an assignment. If you need one, you must apply through HiQ:
http://external-apps.qut.edu.au/studentservices/concession/
You now have two options for assignment extension. There is one assignment extension online form with options for Longer extension and an Automatically approved 48-hour extension. You must select unit, assignment and extension type. More information and extension form: qut.to/late-assessment
If you don’t have an approved extension, you should submit the work you have done by the due date, and it will be marked against the assessment criteria. Assignments submitted without an approved extension will not be marked and will receive a grade of 1 or 0%.
Reviews
We cannot remark assessments. All assessments will be returned with feedback explaining the reasons for the marks allocated. If you require additional feedback or clarification, discuss it with your tutor. If you believe that there is a component that has not been marked in accordance with the criteria sheet, you must identify it in writing to your tutor.
Academic Honesty
Any action or practice on your part which would defeat the purposes of assessment is regarded as academic dishonesty. The penalties for academic dishonesty are provided in the Student Rules. For more information, consult the QUT Library resources for avoiding plagiarism.
Resources
The following resources may assist with the completion of this task:
• Refer to tutorial materials, Microsoft Teams, and any lecture videos.
• Refer to the recommended book.
Questions
Questions related to the assessment should be directed to the teaching team during the workshops or drop-in sessions and also via MS Teams.
The teaching team will not be available to answer questions outside business hours, nor in the hours immediately before the assessment is due.
Assessment Tasks
Task 1 [25 marks] – Group
ProjectsRus maintains information about their project team staff members and the projects for clients. Perform CSDP step 1 ~ 6 and submit your final ORM diagram (not required to submit the results of the
interim steps only the final diagram) for the following business concern.
ProjectsRus business concern
A business called ProjectsRus hires project teams to develop and implement technology for a client. The project team is suitably qualified staff who fulfil the project roles of project manager (PM), software developer(SD), system analyst(SA), database developer(DD), user interface developer(UID), and tester(T). Other project roles are possible, and a staff member can have a different role in different projects. For example, you are the system analyst in one project, and in another project, you are a project manager. ProjectsRus maintains information about their project team staff members and the projects performed for clients. The following table shows the list of project team staff members details including their employment start and finish dates.

A client project is reported in a form of project charter which describes some important information about the project (e.g., the project name, period, scope, members, etc.) as shown in the following. A project team staff member has only one role in the project. As shown in the examples, the full names of the roles are not used in a project charter.

Project ID PRJ_517
Project Name Application to interface dispensing machine to SCM IS.
Project Sponsor ChemistRus franchise.
Date of Approval 15/05/2017 Last Revision 20/05/2017
Project Description A standalone dispensing machine can load onto shelves and dispense prescription medicines (like a vending machine). The standalone dispensing machine needs to be interfaced to the existing supply chain management (SCM) information system
(IS). An application is required to interface between the existing SCM IS and the dispensing machine. The SCM IS lists incoming medicines from suppliers for loading onto the shelves of the
dispensing machine. The SCM IS will also list order information for dispensing medicines to customers.
Project Period (year) 1
Scope Develop and implement an application to interface between the existing SCM IS and the existing dispensing machine. The interface application will need to transmit information to the dispensing machine so that a supplier’s delivery of medicines is automatically loaded onto the correct shelves in the dispensing machine. The interface application will need to transmit information to the dispensing machine so that a customer’s order is automatically dispensed. All transmissions to the dispensing machine will need to be confirmed by reply message. The dispensing machine will transmit and display any error or fault codes.
