The Design And Implementation Of Teaching Website Based On ASP. NET

Along with the development of networks technology, online teaching has already become an important way of the current teaching nowadays owning to its interaction, openness, sharing and autonomy. Therefore, it's very practical to develop a fully functional website to share the excellent teaching resources, so as to provide an online platform for teachers and students to communicate with each other.The website presented in this thesis mainly aims at the course of "Digital Signal Processing", which is a basic course for the students majoring in electronics and information and is developing rapidly. With the emergence and rapid development of the Very Large Scale Integration (VLSI), DSP has developed and improved continuously in theory and applications. It has replaced the traditional analog signal processing methods rapidly in more and more fields, and has opened up many new application areas. To make sure that students can learn this course well, we design the teaching website by means of combining the class teaching and the network learning.Aiming at slow updating and bad interaction in current teaching website, we designed a "Digital Signal Processing" teaching website of B/S structure through the combination of ASP.NET and SQL Server 2005 database.Firstly, the functional requirements of the teaching website have been established on the basis of analyzing the target and the existing problems of the current teaching website. And according to the functional requirements, the development environment of the system, the development tools and the development language have been selected and introduced in detail. Secondly, the modeling program of the system has been designed according to the needing analysis by using UML Object-Oriented modeling method, including the use case diagram, class diagram and sequence diagram. Then, the designing process of the system has been elaborated detailedly by using Microsoft Visual Studio 2005 combined with SQL Server 2005 database, ASP.NET and C#. Finally, the key techniques of this system has been probed thoroughly containing the database connection technology, the design of the class and simple encryption algorithm etc..
