The software that this text will introduce is a multi-function learn the single phrase software, mainly introduced this software manufacture environment, the manufacture process, to operation and its operation methods of the database.The customer can search the single phrase according to own demand, increasing the single phrase, deleting the single phrase, editting single phrase etc.Moreover, it returned to provide a good method that carries on the back the single phrase for the single phrase learners.Each customer can pass to establish an user's name to recite from memory the single phrase.At any time look into own history record, for the purpose of assurance recite from memory the degree of progress ownly.Carried on to elaborate carefully from the angle of the software engineering.It is Adapt Server Anywhere that the development tool of that system is the powerbuilder 9.0 databases of the usages.Key Words:The Electron Dictionary , powerbuilder 9.0, Adapt Server Anywhere电子词典设计与开发4目 录前 言.1 第一章 系统分析.2 1.1 系统目标.2 1.2 系统需求分析.2 第二章 系统总体设计.3 2.1 系统设计思想.3 2.2 功能设计细节问题.3 2.3 系统功能结构设计.4 2.4 模块功能说明.5 2.5 开发工具和环境.6 2.5.1 总体开发工具及环境.6 2.5.2 开发工具简介.7 第三章 数据库的开发与设计.9 3.1 数据库需求分析.9 3.2 系统逻辑分析.10 3.3 数据库的连接.11 3.3.1 程序设计时与数据库的连接.12 3.3.2 程序运行时与数据库的连接.12 第四章 关键模块页面和代码设计.
