(Awoyelu & Tangba, 2010).
2.Introduction
The software development process is connected with overseeing venture unpredictability.
Utilization of strategy has additionally some implication for its usability, viability, versatility,
reliability as well as transportability of the product that is being developed. Also, by having a
wrong strategy could bring about slippages, lack of communication in team and managerial
overheads, prompting client failure. An ongoing report has detailed a huge connection between
the supplier satisfaction as well as the software development methodology which is being used.
(Rajagopalan, S. & Mathew, 2016).

E-business data frameworks enable the transactions to be directed in a coordinated and
broadened data space by evacuating imperatives that are imposed by computing platforms,
systems, as well as applications. The Web advancements not just allow the automation of
organizational processes, yet in addition enable individual customers to associate with
organizational data frameworks at minimal effort. E-business data frameworks are vital resources
as they empower new business models. In this paper, we present the structure and segments of
databases for real online business frameworks (Pant & Ravichandran, 2001).
2.1. Project Deliverable
The main deliverable of the project is developing e-commerce website that will help the
organization to keep the record of inventory which will be updated automatically. All the
security features will be implemented in the system. A manual will be provided with the software
that will help the user to easily understand all the processes that are used to build the system. The
updates will also be implemented.

inventory so that organization can order the items from the suppliers. The system will also help
the organization to monitor the shipping status of the order so that order can be delivered on that
particular address at specified time. The e-commerce system will enable the organization in

capable to impact the decisions. Since organizations these days use management system in order
to support processes as well as accomplish their vital objectives, and also assume the significant
role in the procedures of stakeholder management (Barbara & Roman, 2014). The main users or
we can say stakeholders that are involved in e-commerce system development project are given

5.Functional Requirements
The main functional requirements of the e-commerce system are given as following:
1. User Registration - The system must enable users to easily register in e-commerce system.
The users can choose user name and password accordingly that can be laterly used for signing
into the system. It will help the system to save all the important data like contact no, emails,
address, delivery address into the customers table.
2. User login - After registering, users can easily login into the system. In order to login, user
types his username, password and then click on submit button. If the username and the password
are correct, he is prompted to next page which is select items.
3. Select and Order - Here, in this page, user selects the items by checking its description and
image. He selects the items and put that into the bucket list so that he can place the order. After
selecting all items which he wants, he makes the payment using credit card or online banking
system. The system will be integrated with banks in order to process the customers payments.
After making payment, he selects the delivery address and makes the order. An order number
will be generated which will be unique and will be like a reference which can be used to check
the status of the order later on.
