NIT5130: Database Analysis and Design

Assignment

Semester 1, 2019

Campus: Sydney

Due Date: Week 11 –

Scenario for assignment

Suppose the Victoria University, International Office (IO) needs a database to assist simple and

fast data entry and print reports. The key information is collected from the students during their

enrolment. In order to make this process fast and easy for the students, the data entry has to be

as capable as possible. If the data entry takes too long the student may become unconcerned in

joining the university.

The director at IO requires reporting features to facilitate them to help with rostering, roles and

membership email lists. Some such reports include: organising a roster for the volunteers, finding

all of the people interested in organizing a social function, printing a list of contacts etc. This will be

achieved by creating a database using PhPMyAdmin and WordPress (for forms and reports

design) and making use of supporting features like: forms, queries and reports. A user manual is

necessary to this project as the managers are novice computer users and will require assistance

for using the database.

IO Background

IO, as the acronym recommends, is planned to help the students by providing a friendly place

where they can meet other part-time or full-time students. Facilities and services include: a pool

table, tea and coffee, a kitchen, few games and a number of social events for the students to

attend. If the students have an hour break among classes then they can come to the IO lounge

and relax on the couches, play pool, chat over a coffee and so on. In regard for these facilities to

stay hygienic and well maintained, certain rosters are set up for the student members. These

rosters are generated from the database of students wishing to volunteer for a particular job or

jobs. From time to time notices and documents are sent out to the members to remind them of

their allocated duties and to inform them of upcoming events and activities.

VU Sydney

A range of jobs that need to be accomplished at the IO lounge require volunteers to complete

certain tasks like, washing windows, vacuuming floors, mopping etc, and these may need to be

done at certain times of the day and/or week. IO would like the database to keep track of the tasks

required in each job. They would also like a record of who does what job on what day and whether

it was completed or not. Moreover, University faculties, schools and the course, that students are

in, are very significant to IO so that they can categorize people into study groups and for

mentoring purposes. A new member can be introduced to people doing the same course or in the

same faculty or school. IO would like the database entry screens to be designed for simple and

easy navigation of information in the database. The first screen should contain contact details. The

second screen should be about what IO can do for them, and the third screen should be what the

student can do for IO.

How IO process works

At the time of enrolment, the interested students fill out a form giving their contact details to IO.

They also indicate whether they would like to help out in the duties involved within the university.

The databases are updated with new members every year. This guarantees that the current

database is up-to-date. Reports are then generated from the database that helps the IO team

synchronize and locate volunteers.

The database reports make it easy and simple to generate rosters, mailing lists, organise social

functions and meet nutritional needs of the students. IO would like the make the data entry as

simple and easy as possible for the student enrolment. They would like the reports to be easy to

produce. They also recommended that each school in the university should be linked to its

associated Faculty. So that somebody cannot enter “Faculty of Information Technology” and

“School of Law” as this is incorrect.

Task 1: Database Modelling (Total marks: 50%)

1.1. Develop an Entity Relationship (ER) model to characterize the information requirements of

business illustrates in the case study mentioned above. The diagram of your ER model

must: -Marks: 25%

A. Demonstrate all necessary entities

B. Demonstrate all attributes

C. The relationships between entities

VU Sydney

D. Demonstrate unique identifiers and nature of interaction among entities

1.2. Discovered business rules for your ERD -Marks: 5%

1.3. Map the Entity Relationship Diagram (ERD) into a set of relations in at least Third Normal

Form (3NF). You should show that each relation satisfies the rules for 1NF, 2NF, and 3NF.

-Marks: 20%

For example STUDENT (StudentID, FirstName, SecondName, Phone). This relation is in 1NF as it

does not contain any repeating groups and show primarykey.

Data dictionary:

Your report you must also include a data dictionary. You should briefly describe all entities and

attributes are included, descriptions are clear, reasonable field formats, etc. For example,

“pool-table”

VU Sydney

Task 2: Database Implementation (Total Marks: 50%)

A. Implement your data dictionary to create a relational database in PhPMyAdmin.

B. Populate the database with sample data. Adequate sample data must be included to show

that the queries, view(s), and report(s) work properly

C. Design the following three forms and two reports, requiring a separate query to assure

every of the following information needs:

1. A Student information entry form

2. A form to allow the director to change Member details and update the job and roster

information without losing data integrity

3. A report that prints the students address details

4. A form for the director to fill in the jobs for the up-coming week with the volunteers

available

5. A report that lists all of the people with particular dietary requirements so that this

can be given to the chef before social functions

Submission details:

LATE SUBMISSIONS will NOT be accepted.

Total marks 100, worth 15% assessment for the subject.

Submission due date: Week 11 –

Information of your Group Members

Identify the members of your team with full names and student numbers. Groups are to

consist of three to four members only.

Regulate your own group efforts. Any problems that arise, such as group members not

contributing a fair amount of the work, must be resolved within the group. Lecturer and

tutors will not intervene – so select your group members carefully.

Submission Procedures and Required Format

Your team’s assignment report is to be written in English, on A4 pages. The report should be

written in clear, plain language, so that non-experts can easily understand it. Your report should be

addressed to the Managing Director of your proposed organisation, and should briefly re-state the

tasks you were required to perform and detail the material produced. Include brief instructions on

how to view your system structures, design and implemented. Please note that the Managing

Director is familiar with computers, but has a very limited understanding of technologies such as

PhPMyAdmin and WordPress. Attach all relevant designs and support materials in an appendix.

Assignment submission will be online to VU Collaborate, your lecturer will guide you further about

the process. All sources quoted in your report should be detailed in a Reference Section.

The report must be your own group’s work, i.e., it must be the result of your own reading, thought

and discussion, and the expression of the ideas must be yours.

The submitted work will therefore comprise:

a) Your group’s report

b) Relevant designs and support material

c) Sources detailed in a reference section

d) Declaration form (See Appendix A)
