数字逻辑学习系统设计与实现
摘 要:互联网已成为社会上不可或缺的元素,而在这个网络里最为关键的元素
就是各式各样的系统。同时,人们对信息科学的理解也从低水平发展到高水平。
从感性认识到理性认识。通过信息技术进行相应的管理已经深入人心,通过理性
化、专业化的管理,信息被准确、完整以及快速的存储到一起,便于后期的分析
以及处理,通过这种方式,不仅仅能改变人们通常的处理方式,也能大大提高人
们工作的进度与质量,数字逻辑学习系统为学习数字逻辑课程的学生提供一个准
确、最新的技术与相关文档,浏览目前流行技术的新闻,提出技术上遇到的难点
及问题,帮助其他用户回答所提出的问题,上传想要分享的资源,下载要获取的
相关技术文档,使现代大学生更方便自主的学习。
作为学生通过数字逻辑学习系统快捷的找到想要的资源,上传课程作业,而
且还可以帮助其他用户解决工作中所遇到的技术问题,不需要在去查阅书籍、浏
览贴吧、论坛而消耗时间,让用户以最快的时间找到最想要的技术资源。
在信息时代为数字逻辑学习系统的发展和开拓打牢了基础,为相关机构节省
了大量的物力和财力,减少了资源管理的繁琐程度,提高了管理、查阅的效率,
对学生而言,随时随地可以对自己的作业、系统公告及其个人信息进行修改,在
数字逻辑学习系统管理过程中不存在空间和时间问题;对管理员带来的好处更多,
简化了管理流程,节省了处理时间,提高了管理的准确度;对相关机构来说,改
善了传统的管理模式,扩展了学生们的学习方式方法,所以说,开发数字逻辑学
习系统对于学校是很有用的。
本系统力求结合实际找出一种切实可行的开发方案,经过反复研究和学习,
借助 c#编程语言、asp.net 技术、sqlserver 数据库和 iis 服务器来完成系统的所
有功能,最后进行系统测试,来检测系统的权限和漏洞,从而将系统完善,达到
符合标准。

Abstract:The Internet has become an indispensable element of society, and the most
critical element in this network is a variety of systems. At the same time, people's
understanding of information science has developed from low level to high level. From
perceptual knowledge to rational knowledge. Corresponding management through
information technology has been deeply rooted in the hearts of the people, through
rational and professional management, information is accurate, complete and fast
storage together, convenient for later analysis and processing, in this way, not only can
change the way people usually processing, can also greatly improve the progress and
quality, people work digital logic learning system for students in learning digital logic
course provides an accurate, the latest technology and the related document, browse the
current popular technology news, put forward the technical difficulties and problems,
help other users to answer questions, upload to share resources, download to get the
related technical documents, make more convenient modern college students'
autonomous learning.
As students learn by digital logic system quickly find resources, upload the course
assignments, and can also help other users to solve technical problems encountered in the work,
don't need to go in to consult books, browse the post bar, BBS and consume time, allow the user to
find the fastest time want technical resources.
In the information age of digital logic on the basis for the development of the learning system
and develop, for related institutions to save a large amount of material resources and financial
resources, reduce the resource management of the complex degree, improve the efficiency of the
management, check, for students, wherever they can for their own operation, system
announcement and modify personal information and study in digital logic system management
does not exist in the process of space and time; The benefits to the administrator are more,
simplify the management process, save the processing time, improve the management accuracy;
For related organizations, the traditional management mode has been improved and students'
learning methods have been expanded. Therefore, it is very useful for enterprises to develop the
digital logic learning system.
The system tries to combine the actual find out a feasible development plan, after repeated
research and study, using c # programming language, asp.net technology, essentially a database
and the iis server to accomplish all functions of the system, and finally to the system test, to detect
system permissions and loopholes, thus the system perfect, to conform to the standard.
Keywords: Digital logic, learning system; C# programming language; Essentially a database
