课程设计（电子商务系统） 对于典型的数据库管理系统，尤其是对像电子商务这样的数据流量特别大的网络管理系统，必须要满足使用方便、操作灵活等设计需求。本系统在设计时应该满足以下几个目标：  采用人机对话的操作方式，界面设计美观友好、信息查询灵活、方便、快捷、准确、数据存储安全可靠。  全面展示商城内所有商品，并可展示最新商品及特价商品。  实现网上购物。  商品销售排行，以方便顾客了解本商城内的热销商品及帮助企业领导者做出相应的决策。  查看商城内的公告信息。  对用户输入的数据，系统进行严格的数据检验，尽可能排除人为的错误。  系统最大限度地实现了易维护性和易操作性。  系统运行稳定、安全可靠。 -Course Design (e-commerce system) for typical database management system especially for e-commerce such as the flow of data is particularly large network management system must meet the user-friendly, operational flexibility design needs. In the design of the system should meet the following objectives :

A=alphabet(:,1)+rand(35,1) alphabet是已定义好的字符特征矩阵 A2=sim(netn,A) netn是前面已训练好的神经网络 A2=compet(A2) answer=find(compet(A2)==1) plotchar(alphabet(:,answer)) -A = alphabet (:, 1)+ Rand (35,1) alphabet is the definition of good character characteristic matrix A2 = sim (netn, A) netn that have already trained neural network A2 = compet (A2) answer = find (compet (A2) == 1) plotchar (alphabet (:, answer))
