Design And Implementation Of Network Learning Platform Based On B/S

In the rapid development of information technology era, all trades andprofessions have accelerated the pace of information technology, the degree ofeducation management institutions are getting higher and higher, the campus isbringing into using the office automation system, student management system, staffmanagement system, course scheduling management system, input systemperformance, student dormitory management system which can replace the traditionalartificial management mode gradually and make the management of educationalinstitutions becoming more convenient and quick. With the maturity of networktechnology and the popularization of computers, network learning platform hasgradually become an effective means of teaching aids in the field of education,technology developers design and develop a scale ranging from network learningplatform for everyone to learn.A network learning platform which is designed and developed for the college inthis paper can provide a good network learning environment for students. Thenetwork learning system is based on.NET development platform, using SQL Server2005as the database, C#as the programming language, and uses the B/S systemstructure and the three-tier mode complete. Through the network learning platform,students can watch or listen to various needs of online learning materials, which canbe downloaded to the local computer for repetitive learning, and can also askquestions in view of the don’t understand the content, enhance the interaction betweenteachers and students. Except learning the necessary knowledge in the classroom,students can also find the content they need in the network learning platform as theexpansion of knowledge.In the process of system development, we considered the data security. With thecontinuous development of internet, network security has been put on the agenda; theresearchers will gradually shift their attention to the problem of network security. Ifthe personal password, identity card number and other important information store inthe data table in the form of plaintext without any encryption, the data has greatpotential in the field of information security. When the data in the database are in theform of the original unencryption, internal staff can open the database and browse through the customer information, some hackers can use the computer virus attackdatabase and steal the data in the database, some lawless elements can also steal thedata through illegal means or ways. These methods will result in leakage or loss ofpersonal information, once the database ID number or passwords and other importantpersonal information being leaked to the criminals, the loss of personal property andsome immeasurable serious consequences may be caused. Considering networksecurity factors, in the process of designing the system, we encrypt the information ofthe registered users, which can avoid the disclosure of information. The practicalityand safety of system depend heavily on the data encryption algorithm. We use thethree DES encryption algorithm of symmetric encryption algorithm to encrypt thedata in the database, which can greatly ensure the security of user information andprevent serious consequences for property damage due to leakage of personalinformation.
