ABSTRACT
This work presents the design and implementation of automated auction sales information system for Enugu rent tribunal. An online auction system for auctioning of products includes a server system, plural buyer system, and plural seller systems. The server system comprises a seller interface that performs an online bid setup process including obtaining, from a given seller system, price varying information and quantity information corresponding to the price varying information. The buyer interface communicates to selected buyer system, bid information and product information and also accept from a given buyer system a given quantity needed and a given bid. The price adjustment mechanism determines a given parity price for the given buyer which varies according to the given quantity needed. The bid manager defines a given buyer as a function of the given parity price and a rank of the given buyer in relation to the other buyer.
CHAPTER ONE
1.0 INTRODUCTION
During my research I found out that, auction sales information system is the process of buying and selling system where the buyers are allow to price the goods at any level the buyer wants. Also auction sales system the two opponents can be there when the auction is going on. Auction sales information system is an open multitrade transaction between the sales and buyer. The model allows several trades to enter the same transaction by allowing them to be forked and terminated but it restrict their behaviors in order to guaranties correctness of transaction nesting and isolation among transaction.
Automated auction sales of goods can take place on internet auction site like e – Bey Auction site and one of the few surviving e – Boom Company of nineties. It seems to have a monopoly for internet buyer and sellers. Automated auction sales information provides a framework in which the trade of goods takes place. Buyer, seller, and auction houses adhere to a strict set rule to ensure the fair trade of commodity. As with regular auctions, electronic auction must ensure that these rules are not break under any circumstances. If the rule of an auction breaks down during the auction process the auction is invalid.
The major difference between conventional auctions and electronic auction are that participants never need to be physically present in the same room. On the one hand this can be advantageous as the number of competing participants is potentially huge. On the other, it exposes a number of security risks that threaten the validity of the auction.
Bidders, sellers, auctioneers can cheat and break the rules of conduct. For instant, a bidder might not pay the winning price; a seller may not deliver the lot; an auctioneer may not be bias and not allocate the win to the rightful winner. In order to ensure that the rules are followed at all time the electronic auction must presume that all participants are dishonest and deploy cryptographic schemes to tackle specific security issues and requirements. If we are going to develop and a truly successful multiaucton system our understanding and effective deployment of security method will be paramount.
- STATEMENT OF PROBLEM
The auction system we are familiar with is usually a concurrent system though, it is manually operated; designing an automated or computer based auction system for Enugu state rent tribunal that would be operated concurrently becomes extremely difficult to understand, design, analyze and modify sophisticated object – oriented system often need more advanced and elaborate concurrency features than those offered by current programming languages.
Multiple objects must usually be accessed or updated jointly to correctly reflect the real world, hence great care must be taken to keep related objects globally consistent. Any interruption of updates to objects , or the interleaving of updates and accesses, can break the overall consistency of an object system. Transaction addresses this kind of problem.
- AIMS AND OBJECTIVES
The aims and objectives of this study include the following;
- To examine the present auction system
- To find out its associated problems
- To define the input / output specification required for a new system
- To design an automated and suitable system of controlling auction sales
- PURPOSE OF STUDY
This project is aimed at designing and implementation of an automated auction sales information system, an example of a dynamic system with co – operative and competitive concurrency and how structuring the application using open multitraded transactions has the aforementioned problem.
- SIGNIFICANCE OF THE STUDY
The significance of this study is that it will provide the institute with an opportunity to introduce this new technology, which will also serve as the basis for future research into the topic.
- SCOPE / DELIMITATION OF THE STUDY
This project is restricted to sales department of the Enugu State rent tribunal. The following activities have been identified with the department.
- Periodic physical checking of the items auctioned so far with a view to ascertain the level of goods in stock.
- Keeping an accurate record of all bidders (participant) and bidding entries, including all sales made withdrawals and winners of the bidding process.
- Determine and review of the stock level for different products. Â
