摘要：

本设计尝试用ASP。Net在网络上架构一个网上作业管理系统，以推进教学无纸化，作业电子化，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网上作业管理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ASP。Net的特点、结构框架以及使用方法。接着对网上作业管理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。

本文以实际运用为开发背景，运用软件工程原理和开发方法，采用技术构建一个基于B/S模式的在线作业提交和批改系统。整个开发过程首先对系统进行需求分析，得出系统主要功能，数据流图。接着对系统进行总体设计和详细设计。总体设计主要包括系统功能设计，系统总体结构设计，系统数据结构设计和系统安全设计等；详细设计主要包括系统数据库访问的实现，主要功能模块的具体实现，模块实现关键代码等。最后对系统进行了功能测试，并对测试结果进行了分析总结，得出系统的不足及需要改进的地方，为以后的系统维护提供了方便，同时也为今后开发类似系统提供了借鉴和帮助。

Abstract

This design attempts to use ASP. .net architecture on the Internet an online assignment management system, in order to promote the paperless teaching, and assignments electronically, the development of intelligent management. In this paper, from two angles of theory and practice, on the one which has the function of data analysis online assignment management system design and realization analysis. Paper first of all, the paper describes in detail the relevant concepts of object-oriented analysis and design and technology, especially deep in this system are introduced in application to knowledge, such as: object oriented analysis and design process; System used in the development of the technology of ASP. Characteristics and structure of framework and method of use. Then for the feasibility of online job management system is analyzed, then the system design idea, design goal and the overall structure of the system conducted a clear planning. Finally on the main page, database, application system design and implementation of a detailed explanation.

In the development background of actual application, this paper USES the principle of software engineering and development method, using technology to build a based on B/S model of online job submission and grading system. Throughout the development process, first of all, on the system demand analysis, system main functions, data flow diagrams. Then the system overall design and detailed design. Overall design mainly includes the system function design, system overall structure design, system data structure design and system security design, etc.; The detailed design mainly includes the realization of the system database access, the concrete implementation of main function module, module implements the key code, etc. Finally, the system functional testing, and the test results are analyzed and summarized, concludes that the shortage of the system and the need to improve place, convenience is provided for future system maintenance, but also for the future development of similar system provides the reference and help.
