4. 1. Introduction.
Since the internet has become a popular place to buy and sell goods, online
auctioning services have made their way into most homes. Online auction system is web
based application, in which the seller can sell the goods by sitting in his own house ,so the
main advantage of this application is that there is no more system compatibility
requirement problem. The main advantage of the online auction system is that the user can

way for validity and integrity of contractual documentation. Multiple bidders can be
communicating with a great ease. This system allows multiple bids by single users.
1.1 Purpose
Our main purpose for this project is people invest their money to get
maximum profit and knowledge about our online trading system. Here all type of user can
go and analyses the data of different field and get maximum profit for future investment.
1.2 Product Scope
This web application system will be a online auction system which consists
of the seller, buyer of consumer products. The admin web application will allow the online

5. auction administrator to sell and buy the products through the desired

1.3 Problem Definition.
The problem that usually arises in online auction is that of the buyer’s
uncertainty towards the sellers and their products due to the lack of physical evaluation of
the products. Despite the increased numerous advantages of online auction there are
problems that are still present, unlike in offline markets where buyers can physically
evaluate the product quality and interact directly with the sellers, in online markets the
buyers do not have such opportunity as the buyers only get to evaluate the product quality
via the internet interface that cannot perfectly describe the products. The problem of
product and the seller’s uncertainty negatively affects the key success of the outcomes of
the online auctions. The implementation of an online auction system that provides detailed
seller and product descriptions results in the increased certainty of the bidders towards the
choice of the products and sellers that they make.

2.5 Design and Implementation Constraints
The Mess Management System shall be a Web application system running
over web browser environment. The system shall be developed using java.
2.6 Assumptions and Dependencies
 This system can be used only if the user login with correct password and UserID.
 The further transactions can be carried on only with the permission of the
administrator.
3. External Interface Requirements
3.1 User Interfaces
The Interface will be in the form of a webapp. It is designed to be
functional and minimal in its styling. All products will be displayed in a image and

8. description format. HTML and CSS will be used to setup the page layout and add minimal
styling to make the interface user friendly.

Ram : 256 MB or more
HDD : 40 GB
Monitor : SVGA
Keyboard :101 Keys
Modem : 56 Kbps/ADSL broadband
Mouse : PS2/serial
3.3 Software Interfaces
The server will be hosted using Apache Webserver (Version 2.2.17). It
will also have a MySQL relational database. The main backend processing will be done
using java including connecting to and accessing the database and processing requests.
3.4 Communications Interfaces
The main communication protocol will be Hyper Text Transfer Protocol (HTTP). This will
