1 Introduction
Software that will enhance customer loyalty by employing different security tactics such
as giving each customer a unique identity. The modules that will be included in this software
are; Registration module, checkout module that will record the value of the of purchase for each
and every customer, gift award module that will check the customer who will have spent more
than 1000 dollars at the end of the year and give the award to him or her, the module that will
automatically reset the CIN totals at the end of every year when the organization will be breaking
for holidays. This paper aims at explaining the software development for the Australian
supermarket Coles system.
2 Requirements
2.1 Functional requirement
Functional requirements explain how the software system is supposed to operate by looking at
the components that make up the system[1].
a) Customer registration
The customers will be required to give in their details like their full names, identification
number, their location, the mobile phone number to enable the staff to the monitor the
customers and the system to have the total number of the customers in that organization.
This will be done through customer registration. Once the customer has registered, when
visiting the system, the time, he will be required to give in to the system the name and the
identification number to login.

b) Checkout
This module will enable the organization’s staff to identify the customer in the system
using the customer’s identification number (because it is supposed to be unique for every
customer) and put down what the customer would have bought. This will also help the
supermarket to know the customers that would have spent more than one hundred
thousand dollars to awarded.
c) Account resetting
At the end of every financial year of the organization, before going for holidays, the
system will be required to discard all the customer's records so that when coming back
they should start afresh in the next year.
2.2 Non-functional requirements
The development of the Australian supermarket giant Coles system will focus on the following
non-functional requirements in aid of the functional requirements to ensure the overall
functionality is achieved [2].
a) Performance requirement
Performance of the system is dependent on the bandwidth of the internet and also the
hardware itself.
b) Security requirement
There is only one person who is authorized to access confidential information. All the
information regarding the customers is only available to the system administrator.
c) Software Quality Attributes

Software Solution 5
The system is intended to be user-friendly, interoperable and flexible to ease the
operations.
d) Maintainability
The development uses best practices for coding including modularity and well commented
for ease in the need for future maintenance.
e) Recovery
The system will allow all restoration top already backed up data to allow full functionality in
case of any data loss, in this case, all the data will be auto-recovered [3].

3 Analysis
3.1 Context diagram
Figure 1: Context Diagram
This diagram displays the basic flow of the data within the system [4]. Most operations as a
result of a prompt triggered by the customer. Upon successful registration, a customer can now
proceed with the purchases and a receipt is generated as proof of purchase. On the other, a
receipt is also generated for the cashier and a copy recorded to be used in the calculation of the
various awards at the end of the financial year.

3.2 Level 1 Data Flow
Figure 2: Level 1 Data Flow
From the above diagram, a company is identified as a whole component in the design, through
which promotions are created for the awards of the most spending customer. All the promotions
are made in favor of the customer. A warehouse for the shopping items and the cart for the
individual customer. On the other hand, a customer can build his or her shopping cart, view the
item list, searching for more items and finally can also check the company location.

3.3 Level 2 Data Flow
Figure 3: Level 2 Data Flow Diagram
Here we get close to the main entities involved for the operation of the proposed system. During
a purchase, customer details are retrieved for the completion while for a new customer, the
details are captured before the sale is completed. This result to anew data collection for the
award processing and the overall calculation of the performance to account if by chance the
supermarket has made a profit or encountered some losses.

4 Data Dictionary
This list all the entities used in the construction of the data flow diagram.
Customer- the customer is the main entity for major operations in the running of the business.
Cashier- carriers all the sales and records in the system.
Warehouse- stores all the item of sale within the supermarket. For the operation of the business,
the goods to be sold should be stored within the locality to allow faster operations.
Company- this shows the overall body under which the Australian supermarket is operating,
concerned with the management of the supermarket, the calculation of the profits and the losses
in case of any for the growth of the supermarket.

6 Suitable requirements
6.1 Verification techniques
Software is verified to ensure that the developed system meets the earlier stated requirements
before the last testing is done [5]. The techniques under this include the following reviews;
Technical, Business, and management.
To look at the general working of the organization, the technical review should be done and
business review is done to ensure that it is profitable.

Software Solution 12
Management review should be done to ensure that there is a good rapport between the customers
and the staff to enable smooth running in the organization.

Software Solution 13
6.2 Validation techniques
System validation is done to make sure that it has achieved what the user expects. This will
ensure all the faults are corrected before the final deployment [6]. Validation is done through the
following levels of testing
i. Unit testing
This is testing done on the individual module to ensure that each module operates as
intended.
ii. Integrated testing
Under this level, there properly working, related modules are brought together and tested
if they can correctly work together.
iii. System testing
Testing is done on the complete system to ensure that it works correctly and it is usable.
iv. Acceptance testing
This is the last testing level. It is done by the user to ensure that the system meets the user
requirements and all the functional and non-functional requirements have been achieved.
