Design And Implementation Of Paperless Examination Management System

In the twenty-first century, the rapid development of science and technology today, the rapid development of computer technology, the popularity of a wide range of computer, Web technology leap in the development of e-commerce, e-government era, people are still to release the information for the site has no interest in More time is needed to interact with the user, and can provide back-end database management and control services, dynamic Web site.This paper expounds the necessity of online examination, and its function module design and development process. Along with the progress of modern science and technology, human society is gradually moving towards the informationization, the computer as a high efficient management tools for education mode, the teaching and examination of The Times, the network development and popularization, played a very important role. With the development of information technology and the popularization of computer applications, the administration of higher institutions has entered the information age-- from the original manual records management into the integrated management,namely paperless office. Universities are examination, experiment base, its examination management system should also be more IT application to improve efficiency.The developmental background, significances, aims, function design, system architecture, key techniques, strategies of network security of examination management system were introduced in this paper, then describing the papers related theory, knowledge and technology. On this basis, developing the function analysis, architecture design and detailed design, of examination management system. finally, testing the system. By using of J2EE technology, design which is based on B/S architecture, at the conclusion paperless examination examination management system design methods and business processes, based on the key research-based SSH (Struts+Hibernate+ Spring)-based Web system development methods and processes, which analyzes the structure of the SSH service examinations in the paperless management system integration and application of methods involved in the system development technology and development tools. First, application of the method as an object of the research and development on the paper test examination management system needs analysis, using UML unified modeling method to analyze the paper examination examination management system's main function module, while the use case made a detailed analysis and the analysis presented by UML use case diagram. Then, according to the demand on the system in the analysis of the data model involved in the design, application of data modeling tools to design a paperless examination examination management system involved in the table structure, and gives a paperless service examinations relationship management system data model data model diagrams and data dictionary. Designed the data model, designed the data model into physical data model, and implement database applications with Hibernate persistence layer system data mapping between the design. Then, the application of DAO database access layer of the system was further package, through the DAO layer, allowing the specific business logic and persistence layer separation. Meanwhile, according to a paperless system function module test examination management system designed business logic layer in detail. Finally, in the development of system architecture based on the functional modules in detail the design and implementation, while the system deployment and testing, system implementation to obtain the desired effect.This paper systematically introduces the design of the software development process, firstly introduces the background of the development of software, Secondly introduces detailed design of software process, including database design, function module design and implementation, and system interface design, etc. Software testing is finally.
