個(gè)連接。目前幾種常用的“動(dòng)態(tài)網(wǎng)站”的設(shè)計(jì)方法有：CGI(Common Gateway Interface)；IDC(Inter Database Connec2tor)；ActiveX Data Object(ADO)，相比較而言 ADO 具有容易使用，開發(fā)執(zhí)行快速消耗系統(tǒng)資源較少和占用磁盤空間小等優(yōu)點(diǎn)。很多二手交易網(wǎng)站為了吸引客戶，都創(chuàng)建了自己的網(wǎng)上拍賣系統(tǒng)。它通過Inter 將過去少數(shù)人才能參與的貴族式的物品交換形式，變成每一位網(wǎng)民都可以加入其中的平民化交易方式。s not subregional
