The Designing And Implementation Of The B/S Base Online Examination System

With the rapid development of computer network technology, Internet-based application has been paid attention increasingly since the 21st century, The exam of using computer network has become an important means of student evaluation in the modern education. Many network examination software are produced, and schools, training institutions become more and more interested in them because of their practicalities, efficiencies. It works well for the school to save costs, reduce the burden on teachers.This paper analyzes the design and specific implementation of the online examination system, which based on B/S architecture.B / S architecture is to make application development environment and separated from the application environment, which greatly improves system scalability, security, and reusability. The system used programming language C # as programming language in WONDOWS platform, and used SQL Server 2008 as database system. The system used visual studio 2008 software as the programming environment and .NET 3.5 as development platform and deployed to IIS 7.0. The system achieves many functional modules, such as triple role (teachers, students, administrators) management, all subjects sharing a test system, the establishment of test database, automatic scoring for objective questions and so on, Papers of the kinds of questions can be single choice, multiple choice, fill-in form and essay questions, The unexpected events in the examination process of students due to cause disruption to make an effective solution, and proposed the idea based on SOA and DDD will be online examination system of integration with other systems. The system not only can make objective and fair assessment to learning effectiveness of teachers and students, but also provide fast, accurate feedback of teaching management department, it can meet the needs of the general schools and have a strong practical.
