Design And Implementation Of Web-based Teaching Platform

With the continuous progress of computer technology, the traditional mode reveals many defects in the effective and reasonable allocation of educational resources. Therefore, it is necessary to introduce a Network teaching platform that can rapidly develop and popularize education-related information.The Network teaching platform is implemented online through the SQL server2012 database. The B/S technology is introduced in order to meet the needs of teachers and students in their online exchange. The system consists of six parts: registration, exam management, online testing, examination results management, courseware management, interactive discussion and system settings. It meets the requirements of the school’s network teaching. The construction process of the system is divided into requirement analysis, system design, system implementation and system test etc., each described as follows:(1) In the requirement analysis phase, this thesis analyzes the function by data flow diagram, and then it introduces the function component by function structure diagram. Finally it comprehensively analyzes the non functional requirements of this system from concurrent user number, the response speed, security and reliability, thus forming a complete demand plan.(2)In the system design phase, the thesis completes module division, and designs each module in detail with flow chart. On this basis, the database design is completed from entity relation analysis and database tables, and the thesis constructs a perfect security scheme which can ensure system security.(3)In the system implementation phase, this thesis illustrates the requirements of execution environment, then it describes the solutions to the key problems including database connecting, courseware uploading and courseware downloading, finally the system is applied to the school to enrich the existing teaching methods.(4)In the testing stage, functional testing and performance testing have been carried out. In the function testing phase, the thesis designs test cases for each function, and tests according to each case. In the performance test stage, the Load Runner software is used for simulation test. All problems are modified and the network teaching platform is easy to use and practical.At present the network teaching platform has been built, and it has been used in the school in order to improve teaching quality.
