Project Objective :
The primary project goals consist of:1. Now a days, a lot of people are interested in online shopping. So online-auction management system is a platform to sell or buy products by browsing the internet.
2. This web-management system will help to connect the buyer and the seller on line. A seller can sell his/her product through this web portal without any harassment.
3. On the other hand many companies are willing to spend a lot of money for advertising their product, promoting and for other purposes. Thus by advertising the profit will be attractive and all those advertisement can be gathered in a website and all the users can see it easily.
4. The most important is this website is more environment-friendly compared to traditional advertising method of making the schedule of the auction because it does not require a lot of papers or using the paints to paint on those building that are harmful to our environment.
5. Now the people will get to know about the all the products which are to be auctioned without any loop-holes.
6. The main feature of this web-system is transparency as it is online and nothing is hidden from the user.
5
Project Scope :
The broad scope of the E-Auction project includes: 1. The purpose of this project is to build an on-line auction management system, a place for buyers and sellers to come together and trade almost anything.

5. There is full transparency in this portal. No loop-holes are there.

Requirement Specification :
Domain Description: Why ASP.NET?Visual studio brings us closer to ASP.NET. There is no MVC project type or web forms project any longer, there is just ASP.NET. If you want to mix web forms and web API, or MVC and signalR, go ahead! You are encouraged and supported .New features and functionality are brought in with budget without breaking existing apps. New tools like browser link make building for the web more enjoyable than ever.ASP.NET is open sources ,developed in the open ,and accepting community contributions .one ASP.NET and VS 2013 added some amazing new tooling enhancements for HTML5,CSS3 and java script.Whats available on ASP.NET today and where is ASP.NET headed tomorrow and what do you need to know to best support the code you have written and the code you will write.
Problem Definition: Virtual auctions on the internet. The seller sells the product or service to the person who bids the highest price. For sellers , online auction open up new sells channels for new product and offer buyers favorable purchasings conditions .online auction have effectively created a giant virtual marketplace where people can gather to buy ,sell, trade and check out the goods of the day.

Advertiser just can upload advertisement and maintain their advertisement. Admin can maintain all members and advertiser details, maintain website layout, blocking member and so on. b)Forget password: This module is giving user a chance to get back their password once they forget their original password. When users forgotten their login password, they can send a request to the system. After that the system will generate the email and resend the password 9
to the user personal email address and they have used to register before so the users can be login again to the system.Auction Modulea) Release item: This module allows only the admin to post the items that the admin wish to have auction on.

Future Scope of Improvements: This web-system can improve a lot. This website should improve to keep track the transaction between buyer and seller.
Other than that the web-system should can let seller give discount to their product when their product almost end duration but still nobody wants to buy.
This website can be improved by keep track the try log-in time. If exceed three time then it will block that ip address.
This can be improved by adding a live chat box to interact with the customer care if the buyer faces any problem.
