電子商務(wù)數(shù)據(jù)庫平臺管理系統(tǒng)

摘 要
電子商務(wù)是一種新興的、處于發(fā)展過程中的現(xiàn)代商務(wù)方式。電子商務(wù)活動是通過公共計算機通信網(wǎng)絡(luò)進行商務(wù)活動的現(xiàn)代方式，該方式將突破傳統(tǒng)商務(wù)在時間、地域上的限制，成為方便、快捷、安全可靠的新興電子化商務(wù)活動模式。電子商務(wù)將以巨大的速度增長，并給金融業(yè)帶來巨大影響。世界的經(jīng)濟金融狀態(tài)也將受到深遠的影響。信息交流和數(shù)字化電子貨幣在空間地域上的突破將促進經(jīng)濟發(fā)展，但也帶來經(jīng)濟金融管理上的困難。
   在開發(fā)本系統(tǒng)的時候，采用PowerBuilder作為開發(fā)工具，結(jié)合當前各國的電子商務(wù)發(fā)展情況，與國內(nèi)眾多同類系統(tǒng)比較后，很好的對系統(tǒng)進行了分析和設(shè)計，旨在設(shè)計實用廉價的電子商務(wù)平臺。在開發(fā)的系統(tǒng)中，使用數(shù)據(jù)庫等各方面的知識，對大學(xué)所學(xué)知識做了一個很好的總結(jié)加深。作為一個先進的電子商務(wù)數(shù)據(jù)庫平臺管理系統(tǒng)它具有基本商品管理功能，采用B/S/S三層結(jié)構(gòu)體系，對重要的數(shù)據(jù)進行保存、刪除、打印等處理，便于用戶操作。本論文首先介紹了電子商務(wù)的發(fā)展，分析了國內(nèi)外電子商務(wù)發(fā)展的形勢；第二部分對系統(tǒng)進行了需求分析，確定了系統(tǒng)的功能模塊；最后，對本系統(tǒng)的程序設(shè)計作了詳細的描述。
本系統(tǒng)的開發(fā)使企業(yè)能妥善的運用網(wǎng)絡(luò)低廉的成本、高效率的特性、快速安全的完成企業(yè)的各項流程。

Abstract

E-commerce of the summary is a kind of new developing one, modern commercial way during the course of developing. The electronic commercial activity is through the public modern way of carrying on the commercial activity of communication network of computer, this way will break through the traditional restriction on time , region of commercial affair , will become the convenient , swift , safe and reliable new developing electronic commercial activity mode. E-commerce will increase at the enormous speed, and bring the tremendous influence to financial circles. The economy and finance state of the world will receive far-reaching influence too. Information interchange and digitized electronic break-through on the space region of currency will bring about an advance in economy, but bring the managerial difficulty of economy and finance.
 When develop this systematically , adopt PowerBuilder as the developing instrument , combine the present e-commerce development of various countries, with numerous domestic similar systematic comparison, the very good one has been analysed and designed about the system, aim at designing the practical and low-priced e-commerce platform. In the system that is developed , use the knowledge of various fields , such as database ,etc. , learn to do a very good summary to strengthen in knowledge to the university. It has basic functions of management of goods as an advanced e- commerce database platform administrative system, adopt B/S/S three layers of structure system, keep , delete , type etc. dealing with to the important data, it is convenient for user to operate. This thesis has introduced the development of e-commerce at first, has analysed the situation of domestic and international e-commerce development; Second part Have carried on the demand and analysed to the system, have confirmed the systematic function module ; Finally , did detailed description to the design program of this system.
Development of system this enable enterprise application network cheap cost , high-efficiency characteristic , fast safe completion every procedure of enterprise properly. 
Keywords: E-commerce、Management System、WEB、Database
