1.0 Introduction
1.1 Purpose
The basic purpose of this document is to present the detailed requirements for Amazon. Buyer
and Seller are the main parts of this system. By building this system we will facilitate the Buyers and the
Sellers. Through this system the buyers can buy product. Sellers can easily sell their products and get the
payment. Buyers can search for any item, see reviews, compare them with other similar products. They
can also add those items in their shopping cart and access them just by logging into their account. The
Sellers can add their items in the particular item list. They can view the status of their product. Buyer and
seller both can edit their personal details.
1.2 Scope of Project
This document is intended for providing an abstract overview of Amazon and general overview
of entire project. It will give the access to the Buyer and the Seller to share their important data and to do
all activities between Buyers and Sellers related to business safely.
More specifically, this system is designed to allow the sellers to sell their product directly to the
buyers. The sellers decide the price of a particular product. The buyer may get some discounts as per
special occasion and events. The buyers can also gift any product just by giving any shipping address.
Cancelling orders and returning any item is also possible.

1.5 Overview of Document
The next chapter, Overall Description, of this document gives an overview of the functionality of
the product. It describes the informal requirements and is used to establish a context for the technical
requirements specification in the next chapter.

The third chapter, Requirements Specification section, of this document is written primarily for
the developers and describes in technical terms the details of the functionality of the product.
Both sections of the document describe the same software product in its entirety, but are
intended for different audiences and thus use different language.

2.3 User Characteristics
The three actors of the system, Seller, Buyer and Admin, are expected to be Internet literate and
be able to use search engine. The main page of the website will have the search function and links to
other functions like log in, sign up, order history, Cart items etc. The three actors are also expected to
use buttons, pull-down menus, and similar tools contained in forms of certain pages like log in, sign up,
etc.
2.4 Non-Functional Requirements
The system will be on a server with high-speed Internet capability and very fast processing
machine. The actor will be able to communicate with system via a website through a web browser. The
speed of actor’s connection will depend on the actor’s hardware and Internet speed rather than
system’s hardware as system’s hardware is expected to be much faster than that of actor’s hardware.
The database will be linked to the system and will be readily available at all time to the system. The
system will host the website and understand the communication from actor via website.
