資源簡介

易買網(wǎng)購物網(wǎng)站的開發(fā)是北大青鳥課程學(xué)期的階段項(xiàng)目，所開發(fā)的是一個(gè)類似于淘寶網(wǎng)的購物網(wǎng)站，根據(jù)不同的購買需求進(jìn)入相應(yīng)的頁面。可以進(jìn)行搜索，并顯示最近瀏覽過的商品。 　　北大青鳥課程研發(fā)組在S2的課程中加入了易買網(wǎng)這個(gè)購物網(wǎng)站的開發(fā)項(xiàng)目，從某種程度上說明了北大青鳥的學(xué)生在學(xué)完第二學(xué)期之后就可以獨(dú)立開發(fā)出像與淘寶類似的購物網(wǎng)站。 　　IT技術(shù)最重要的就是時(shí)間，北大青鳥課程中貫穿的經(jīng)典的項(xiàng)目案例，幫助學(xué)生獲得最大限度的成長。
