Java在线学习系统
摘 要
本文采用自顶向下的结构化的系统分析方法,阐述了一个功能全面的在线学习系统的开发过程、操作流程及其一些核心的技术。本文首先进行了项目概述,简单介绍了项目开发的背景、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,分析了系统的组织结构,具体完成了在线学习系统的需求分析、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,得出了系统的业务流程;之后是系统分析,具体完成了数据流分析和数据字典;系统设计阶段主要完成了功能模块的划分、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了详细设计,形成了本系统的功能模块图,在此基础上选择了合适的开发模式;数据库的设计先进行了概念结构设计,之后进行了逻辑结构设计,最后完成了数据库表的设计。
根据前几个阶段的分析和设计,本系统在设计方面采用B/S模式,同时使用JSP技术进行基本页面的设计与功能实现,后台数据库选用SQLSERVER数据库。本系统的设计实施为在线学习系统的运行做基础,为在线学习系统提供良好的条件。

Abstract
This paper using the top-down structured systeM analysis Method, this paper expounds the functions of a coMprehensive course website developMent process, operation process and soMe of the core technology. This paper first on the description of project, introduced the project developMent background, the purpose of the project developMent and the significance of developing project; The next stage is systeM planning, through the actual business process of the investigation and research, and the analysis of systeM structure, specific coMpleted quality course website needs analysis, feasibility analysis, the current business process analysis, and through to the current business process optiMization, concludes that the systeM of business process,After the systeM analysis, specific coMpleted the data flow analysis and data dictionary; SysteM design phase is coMpleted the function Module and database design and systeM interface design. This phase of the function of each Module of the detailed design, forMed the systeM function Module chart, on the basis of the choice of appropriate developMent Mode; The first database design the concept structure design, on the logical structure after design, finally coMpleted the design of database table
According to forMer several stages of the analysis and design, this systeM in the design on the B/S Mode, use at the saMe tiMe JSP technology of basic pages design and function realization, the backend database choose SQLSERVER database. This systeM design for asseMbly language iMpleMentation of the operation of the auxiliary JiaoXueWang do foundation, to provide auxiliary asseMbly language JiaoXueWang good conditions.
