A Analysis Of The Online Auction System And A Simple Implementation Based On WSRF.NET

The online auction system is a result from the continous development of the social economy,enhancement of the people's living standard and the abundance od the quality and quantity of the commodities.It can provide people the personal service and allow persons to join in solo or many auctions simulatively.Its content is critical fro seller and buyer.As a part of computer appliance,using web service to plan and develop the online auction system,it has lots of advantages which the traditional system doesn't have.The WSRF(Web Service Resource Framework)is a set of specifications that describe the relationship between "stateful resources" and web services.Meanwhile,WSRF.NET is an implementation of the WSRF specifications on the Mictosoft .NET platform.WSRF.NET consists of a set of libraries and tools allows web services to be transformed into WSRF-compliant web services.WSRF.NET uses the IIS/ASP.NET architecture for web services;that is WSRF.NET services are web services.The major content of this article is that analyze the now using online auction system,and based on the WSRF.NET platform,develop a simple auction system.First analyze the now using auction system,we can get the 10 common functions:Identify resource,set up one's favourite,resource auction,negotiation, manage bid,manage the auction room,manage credit,deal with repay,provide message function and mange ads.After the analysis ,implement the development.First,I introduce some specifications about WSRF.Then based on them, illuminate the specifications I needed nad the steps of creating new web service. Give a particulare illumination to the core contents of my article:Resource,Resource Property,IResource,PortType and Notification.After illuminate their concepts, function, construction and implementation,I use a simple delivery example to show what I said above in the form of code.Based on the above core contents ,I develop this system.i illuminate the steps of development particularly using the code or chart.Adding additional functions to the original system to form a more complicated system,until construct a complete system.By running the system,we can discover the system has some feature of simple code,stable performance and easy using.So,we can evolve this system to a commercial system which is stronger and more complete.
