摘 要
随着计算机性能不断提高,价格不断下降,计算机在民间的普及率已经十分高。随着越来越多的人购买了电脑,就显示出一个问题:由于很多用户都是以家电的性质购买的电脑,而没有多少计算机基础。虽然针对这些用户的培训机构都将其教学难度一降再降,但还是有很多用户无法理解其中的原理。而作为计算机基础的文字录入也不例外。
本设计尝试用VB架构一个输入法模拟系统,以推进计算机教学图形化,过程电子化,管理智能化的发展。本文从理论和实践两个角度出发,对一个具有数据分析功能的输入法模拟系统进行设计与实现分析。论文首先较为详尽地介绍了面向对象分析与设计的有关概念与技术,特别深入介绍了在本系统中运用到的知识,如:面向对象的分析设计流程;系统中所用到的开发技术VB以及ADO的特点、结构框架以及使用方法。接着对输入法模拟系统的可行性进行了分析,然后对系统的设计思想、设计目标与系统的整体结构进行了明确的规划。最后对系统的主要页面、数据库、应用程序的设计与实现作了较为详细的讲解。
本输入法模拟系统是在Visual Basic 平台上运用VB技术来实现的。其主要功能有:输入信息管理,数据导入管理,数据查询,数据备份,数据还原等。论文在撰写过程中,力求将理论与实践应用相结合,对各种理论进行阐述的同时配合系统从实际应用和操作技巧上加以说明,希望能够更充分地体现到这些知识与技术在本系统中的应用与实现。

Abstract
Along with the development of Internet technology, daily life can not already do without the network. The life and work of the social people of future will depend on the development of digital technology more and more ,Digitize more and more, the networking, electronic, virtual. Development course and present application state and development trend of Internet, can believe network technology great change life and working way of us fully, Even a certain change will take place in the values of the society.
This procedure tries to build up a bookshop in the network with VB, So that every customer needn't go out and can do shopping easily through surfing the Net at home .this article is analyzing the design and realization of an online bookshop with Data Mining function, from the views of theory and practice. Starting with introducing concepts and techniques of OOA and OOP in detail, especially introducing the knowledge which apply for this system, such as: the feature and flow of OOA and OOP; analyzing the feature、structure and using method of developing techniques VB and ADO which using in my system. And then, this article analyses the feasibility of the system, then minutely layouts the design thoughts, goals and the system holistic framework. At last, this article minutely explains the design and realization of Web page layout, data base and application program of our system.
This online bookstore system uses VB technology to realize on Visual Studio.Net platform. Its main function has: manage users, new books on sale, look for classified books, search books, collect favorite book, process of purchase, sales list, the comment of the books, website's management, etc.
During the course of writing this article, I strive to integrate theory and practice. While expatiating the different kind of theories, I illuminate the application and operation skill combining the system so as to fully incarnate the application of these theories and techniques to this system.
