Functional requirements
The functional requirements of the system to be developed for the Coles Organization
are:
 The system should be able to provide the details of the product and the also provide a
brief description of the products available in the system. The Products are access by the
product names.
 In addition to the details of the products the purchase of the products. Each of the
purchases made by the customer would be stored in the system with the PurchaseID. The
details would also include the CID providing the details of the customer and the SID is
used for the details of the staffs that would be handling the purchase. Additional details
such as PurchaseDate and Quantity is also recorded for a particular purchase.
 The details of the customers are also stored in the system with the CID being used for the
details of the customers as a reference. The customer name, the address of the customer
and the telephone number of the customers are also stored in the system. The details of
the customers are stored in the system during the registration and the selection of scheme
for the customers.
 The scheme details are also stored in the system with the name of the scheme and the
description of the scheme is also stored in the system.
 Additionally, the details of the staffs are also stored in the system which are referred by
the SID which is a unique Identification for the staffs.
 The system also provides the report for the customers who are eligible for the gifts for the
purchases that they have made throughout the year.

Non-functional requirements
The non-functional requirements of the system that is being developed for the Coles
Organization are described below:
 Scalability: Scalability is very important for the system which is being developed, the
system should be able to store a huge amount of the data as the organization is a growing
one and would be having a high range of data to be stored in the system and this would
increase infinitely and hence, there is need for the scalability of the system.
 Availability: The system is made available to the staffs and the customers in the system
on 24x7 basis as the business of the organization should not stop and the customers
would be able access the system on a 24x7 basis, hence, the requirement of the criteria of
availability of the system.
 Usability: The system design should be very useful and optimal for the users. The users
should be able to have an attractive interface and the navigation and menu features in the
system would be developed in the system with great efficiency. The system should be
convenient to use for the customers and the staffs.
 Reliability: The system should be reliable enough so that there not much error and the
system should not be unresponsive. Hence, the reliability of a system is very important
factor and data stored in the system should be protected efficiently.
 Maintainability: The maintenance process of the system and cost of maintenance for the
system should be minimal and the maintenance of the system should be hassle free for
the organization. Hence, maintainability of the Coles system is very important.
