摘 要

站、自学考试网站等;但却鲜有针对教学考试类学科的考试网站的建设。而教学

考试类考试,是一门与计算机网络紧密相关的学科,是主要的基础考试。为了使学

生随时随地都能方便快捷的学习教学考试,也为了教学更完备,构建教学考试的

学习网站必要的、也是必需的。本文以高校教学考试为研究背景,对教学考试网

站进行研究。考试网站是采用 B/S 模式、基于 ASP 多层架构的体系结构进行设计

开发的,数据库采用了 MySQL。通过对教学考试及考试网站的调查分析,本文给出

了考试网站的目标,详细分析了教学考试中的教学资源管理、习题库管理、试卷

管理、在线考试、师生互动的业务流程,详细描述了各业务的功能需求;分析并给

出了考试网站管理过程中的数据流图。在此基础上,完成了各个功能模块的设计,

包括用户管理、教学资源管理、习题库管理、试卷管理、在线考试、师生互动等

Abstract

In the rapid development of computer network, various courses website after

another, especially English-language Web sites, self-study website; But seldom does

the construction of the course website for math class disciplines. Mathematics

courses, a computer network is closely related to the subject, is the main foundation

courses. In order to make the students anytime, anywhere convenient learning

mathematics, but also to teaching a more comprehensive learning site build math

courses necessary and required. In this paper, the research background of mathematics

courses, study mathematics curriculum website. The course website is the use of B / S

functional requirements of each business; analysis and gives a data flow diagram in

the management process of the course website. On this basis, the design of various

functional modules, including user management, teaching resources management the

exercises database management, paper management, online examinations,

teacher-student interaction module, and describes the specific features of each

functional module; detailed papers of each functional module processing process

design and simple algorithm design, and gives the data model of the system and the

structure of the database design; final paper gives a concrete realization of the main

modules of the system. In the study of the subject, but also try to solve the special

symbol input and output, and access to the pictures, math and other issues. The
