【正文】 聯(lián)網(wǎng)絡，它遍布全球，將世界各地各種規(guī)模的網(wǎng)絡連接成一個整體。s web cams understands fully “enjoys a trip to between the world, the work does not have carefree which the limit” brings. Along with the Inter swift development, causes the work application daybyday widespread. If electronic merce, Egovernment, online medical service, online entertainment, work game, work teaching and so on. This graduation project39。 本論文就畢業(yè)設計的內容，系統(tǒng)地闡述了整個網(wǎng)上 書店售 書系統(tǒng)的功能及實現(xiàn)。當錢天白教授于 1986年 9月 14日在北京計算機應用技術研究所內向德國卡爾斯魯厄大學發(fā)出第一封電子郵件“穿越長城，走向世界”的時候，他也許不知道自己推開了中國信息時代的大門； 1994 年 4月 20日，中國科學院計算機中心通過美國 Sprint 公司連入 Inter 的 64K 國際專線開通，實現(xiàn)了國際互聯(lián)網(wǎng)的全功能連接，從此中國邁入互聯(lián)網(wǎng)信息時代。本系統(tǒng)界面簡單直觀，易于操作和使用，交互性強，完全基于 Inter 網(wǎng)絡。s function and realizes. Has realized from the merchandise control, the classification of goods and the inquiry, realizes to the shopping cart, user order form processing, arrives at the chatroom again, the manager system. Basically has realized the electronic merce function flow, can realize the user and the business online carries on the modity exchange. This system contact surface simple directviewing, simplify operation and use, interactive is strong, pletely based on the Inter work.
