How is data modeling different from database design? -

Instructions: There is an imperative requirement in this assessment; you must submit different versions of the files by Thursday of week 4 at midnight (Sydney time). The files should ideally be of excel format. The data in the files should be composed based on the following scenario: Torrens University Australia (TUA) is interested in a new Student record management system. This system needs a database to manage students enrolled, courses students enrolled in and staff facilitating the course. You will need to store and manage the data for the enrolled students, courses and the staff assigned to the courses.

2DATA MODELLING AND DATABASE DESIGN
What is Excel:
Microsoft excel is a special type of tool or software from Microsoft. Ms excel is
included in the Microsoft Office suite (Hubalovsky & Musilek, 2014). Ms Excel can perform
several tasks, and this is the best tool where a person or an organization can use for this
application for storing information.
Any person can edit or delete the data. Excel store every data in a spreadsheet. The
cell-based calculation can be done in excel, pivot table and many graphical tools are available
in Excel. With the help of a spreadsheet, a person can store their monthly budget, and track
every business expenses. Basically, with the help of excel, an organization can keep its data
in a structured format.
In this project, MS excel is used to develop a database for Torrens University
Australia. They want to develop a student record management system that can perform store
every student information, staff information and enrollment information. This information
will help the university to keep every essential detail and maintain the workflow. This system
can add, delete or modify any information.
To develop the university database, creating four spreadsheets to store every
information, version 1, version 2, version 3 and version 2. The details description of this three
spreadsheet are described below:
Version 1 (V1.0):
In Version 1, storing every information of student, course, enrollment information and
staff information. Every student is uniquely identified with their student id number. This
sheet stores student’s first name, last name, address, and date of birth. Every course has its
course id number. And course name store at the course name column. Every enrolment

information is essential for the university. Enrolment number and enrolment date are created
to store enrolment information. A student can enrol for courses, so course details are also
necessary to store in this database. Every course has its course id and course name. For every
course, a specific staff member is assigned.
Designing Version 1:
Version 1 spreadsheet is in 1nf. The first column in this spreadsheet is student id. This
is a unique column that can store every student id number uniquely (Coronel & Morris,
2016). Every student can uniquely be identified with their student id number. The second
column is the first name. This column store the first name of every student number. This is
one of the essential columns for this database. The third column is the last name. Last name
column can store every last name of a student. Next column is student contact number.
University authority can contact them with the help of contact number. Every student must
have a unique phone number. Next column is the date of birth. This column can store the date
of birth of every student. This column can store the data with the data format. Using the date
format for date attributes can help university authority to identify every student date of birth.
Next field is addressed. This file can store every address of each student. Keeping student
address in speared sheet is helpful for university authority. Next column is course id. A
student can enrol for a course at the university. Course id can store every id for a specific
course, and every course can be identified with their course id number. Next, the column is
the course name. This column is able to store every course name. Torrens University offers
many courses to students. The course name is one of the essential columns for this
spreadsheet. To pursue a course, every student needs to enrol for the course. Each enrolment
is identified with its enrolment id number and this spreadsheet also record every enrolment
date. Enrollment data can provide the proper date of student enrolment. University authority
store every enrolment date in the enrolment date column. Every staff is assigned for a course.

Staff plays a big role in this spreadsheet. Every staff has its unique id number. Next column
of staff id is staff name. This column can store the name of the university staff.
Version 1 sheet is the complete form is this database. This sheet record every essential
record for the university.
Version 2 (V1.1):
This is the copy of spreadsheet Version 1. In this spreadsheet, few changes were
made, changes are:
 The last two-row were updated.
 Add five additional record.
Apart from these, nothing changed in this spreadsheet. It is almost same as version 1
spreadsheet. Changes part is highlighted in the yellow colour.
Version 3 (V1.2):
This version is also the same as spreadsheet version 2. In this version, two attributes
were added. Two attributes are:
 Staff_mobile. This column record every phone number of staff.
 Date_of_join. This column provides the date of joining of university staff.
Apart from the above changes, it is also same as previous versions spreadsheet.
Version 4 (V1.3):
This is the extended version of version 3 spreadsheet. In this spreadsheet, a few
changes were made while creating a database for the university. In this sheet, five attributes
were deleted. Five attributes are last name, date of join, staff mobile number, enrollment date
and the address of the student. Apart from deleting five new rows were added.

Benefits of using excel:
Ms excel offers several features to companies. It helps to maximize the data values
and help to control costs in an effective way. The befit of using excel for this database are
discussed below.
 By using MS excel university, authority can make great charts that are helpful for
university. Excel provides the business user to use its full features. In this database,
every data is inserted into the individual's cells in columns and rows format. By using
a pie chart and graphs, excel can represent the spreadsheet in a more visually
effective way.
 University authority can represent every data in different colour shades. This can be
more visible for every user.
 With the help of excel, the university authority can bring every data together. The
spreadsheet can import images and texts that can help the user to reduce the
workloads.
 Excel is also available online. University authority can use this online; there is no risk
of data loss.
