Abstract
In reality, more and more people have desires to sale goods what they have been used. But there is a limitation of sale for traditional methods.

So that, there is a safeguard to exchange normally.
This thesis divided into five main modules, respectively is: First, introduction selected topic background and significance and system development present situation; Second, introduction data bank technology, and the plan of B/S structure WEB programming technique; Third, carries on the demand to the current enterprise to analyze and to propose the solution; Fourth, carries on the design according to the solution to the system; Fifth, carries onto the work plan statistical analysis system tests and obtains the test result.
