Southern College English Level Training Online Exam System Analysis And Design

With the development of the times, the type of examination in the constant increase and examination requirements are constantly increasing, so the teacher’s workload will be more and more big, the traditional examination mode has many disadvantages, such as the examination procedure is tedious and error prone. Can say that the traditional examination method has already can’t adapt to the demand of the modern examination. Therefore, to achieve paperless examination has become necessary to apply the computer technology.This system based on the Southern College English online exam simulation as research background, the status and application of online examination system at home and abroad to do an investigation and analysis, combined with the actual situation of our college English tests, using the design object oriented system analysis are described in this paper needs method. Including business requirements, functional requirements, data requirements and non functional requirements, business process diagram, use case diagram and class diagram gives the system concept, the use case description; in the system design, system design and module design, including training online simulation test system function module, this system is divided into teachers, students and the administrator trigonal color. Has the examinee management, test management, test management, online examinations, examination management is composed of five subsystems, the structure chart of the function module design gives them (package diagram, class diagram, sequence diagram) and processing flow chart, detailed design, the interface design, and use the entity class diagram, E-R diagram and database table the structure of the database design is discussed in detail; the system with multiple candidates at the same time, the number of online examination question bank random questions, time limit, to score, the test question input, modify the important function of database, user management, that is to achieve paperless examination real, basically meet the basic requirements of College English Training Simulation online examination the. Finally, the content of the study are summarized, the author’s work, points out the deficiencies of this paper, and the further work is prospected.
