Design And Implementation Online Teaching VOD In Universities Based On.NET

With the development of information technology,the way of teaching become diverse.But most of the teaching methods are still the teacher lectures,student records,teacher's way of answering questions.Many students in the classroom are not easy to understand,they need to continue to review and consolidate.If we can develop an online video on demand system,so that the students in the class after watching video review homework,to improve the understanding of the knowledge of the students.We research a college and understand the specific needs of users.The system design using B/S mode and three level architecture to build a software development platform,the network transmission using the star structure,the specific programming language using C# language.This project will complete the following specific work:(1)The analysis of the needs of the system,we collect date and understand the key technologies of the system(such as ASP.NET,C#,etc.).To build the star network of the design process,we will study the layout and use of the network.(2)First of all,this design to complete needs analysis and system analysis,the system is divided into two roles which are the administrator and the user.In the design process,the user role has the registration,video on demand teaching video,feedback video information,collection of video and other functions;The administrators have a rolling notice management,teaching video management,registered member management,video evaluation management,online communication management and other functions.This design through the use case diagram,flow chart to explain how to achieve these functions and using Server SQL 2008 to realize the concept design and logical design of the database,finally to the various modules involved in the data management functions to improve.(3)This design use code to achieve the entire system.The coding to achieve the process will use modular idea,after the design is completed,the test method of the black and white box is used to test the function and performance of the software,and the defects and deficiencies in the software are corrected.Finally complete the design work of the software.After the application of the project,administrators and users can use the relevant functions in accordance with the different permissions to use the video on demand system,which will help colleges and universities to carry out teaching work.The future we will vigorously promote the system.
