文档介绍：摘要
采用自顶向下的结构化的系统分析方法,阐述一个网络课堂网站的开发过程、操作流程及其一些核心的技术。首先进行项目概述,简单介绍项目开发的背景、项目开发的目的和项目开发的意义;接下来是系统规划阶段,通过实际的业务流程调研,分析系统的组织结构,具体完成网络课堂网站的需求分析、可行性分析、现行业务流程分析,并通过对现行业务流程的优化,得出系统的业务流程;之后是系统分析,具体完成数据流分析和数据字典;系统设计阶段主要完成功能模块的划分、数据库的设计和系统界面设计。该阶段对各个模块的功能进行详细设计,形成了本系统的功能模块图,在此基础上选择合适的开发模式;数据库的设计先进行概念结构设计,之后进行逻辑结构设计,最后完成数据库表的设计。
根据前几个阶段的分析和设计,在设计方面采用B/S模式,同时使用ASP技术进行基本页面的设计与功能实现,ess数据库。

Abstract
In this paper, top-down structured system analysis method, described parts of a full-puter quotation system development process, operational processes and some of its core technology. This paper carried out the project overview, a brief background of project development, project development and project development objective of the meaning; followed by the system planning stage, the actual business processes through research and analysis of the system'anizational structure, specifically plete puter parts quotation system needs analysis, feasibility analysis, the existing business process analysis, and optimization of existing business processes, business processes of the system obtained; followed by system analysis, the specific data flow analysis plete data dictionary; pleted the design phase the main functional modules of the division, the database design and system interface design. This phase of the function of each module in detail the design, forming a functional block diagram of the system, on this basis, have chosen the right development model; database design first tested the concept design, followed by a logic design, and pleted the design of the database table.
According to the first few stages of the analysis and design, the system used in the design of B / S mode, ASP technology, the basic page design and implementation of function, use Access database backend database. The design and implementation of the system parts for puter to run a foundation quotation system puter parts quotation system to provide a good condition.
