Based On. Net-school Examination System

With the current increase of Chinese vocational education scale, teaching management tasks in vocational institutions are becoming arduous. Examination as the core part of educational administration, examinations organization according to the traditional manual method is inefficient. The rapid development of information technology, the maturity of computer and network technology set up gradually have provide a solid technical support to Information Construction of schools,such as the establishment of a multi-level, information network management system for the examination, The use of modern computer technology to achieve the traditional examination process in the organization of test paper, carrying on examination, paper marking and analyzes process etc. And this can improve academic work efficiency, implement standardize management, and meet the needs of the school's future development.This thesis with, the current examination affair of Henan information management schools as it's background, and in accordance with the basic principles of software engineering, there we gathered the examination management system's requirements, and have used UML to set up the demand model, and conducted a detailed requirements analysis. On these bases, the overall structure of the system and function modules have been designed, and the structure of system database tables and relationships between them were designed too. In particular, automated paper organizations were deeply studied, and with compares of some Algorithms having been used in paper organization cautiously, we selected Genetic Algorithm to complete the Test Paper organization.Object-Oriented method was used to the system implementation. Using .NET framework, Using ASP.NET and C# as its technology port, and using MS SQL Server as its back-end database, school examinations management system based on B/S structure was ultimately designed with the three-tier architecture. These functions such as exam management, intelligent paper organization, exam database management, paper management, online examinations, results statistical analysis of exam and other major functions are achieved in this system. This system meets our school's and requirements of Intelligent and Informational examination management to a great extent.The security of this Web application is a systems engineering. Incorporation with the operation principle characteristics of ASP.NET, this thesis just completed a detailed study of the coding technology of safety management system. And this study Includes the encryption of database connection string, preventive measures against SQL injection, the default ASP.NET error messages modification etc. This system was security reinforced from many aspects , and provide a safe barrier to management systems.Finally, with system development completed, we summed up the system features, advantages and shortcomings. And prospects the future development prospects of our system.
