The Design And Implementation Of Southwest Jiaotong University Press English Reading On-line Exam System

This topic comes from the Southwest Jiaotong University Press, the publisher requests the examination system which is binded with the materials to meet the students under the premise of the basic test function, also requires examination affairs to minimize the work of teachers to achieve the automation of marking, To solve the above problem, we develope a set of online examination system and the system activates material volumes by using activation codes,and prevents the piracy phenomenon well.The system designs a on-line examination system of three layer architecture B/S mode based on the.NET framework. Development tool is Visual Studio 2010,the language of realization is C# and web server is IIS. The database is SQL Server2008 R2 database management system. What is more, in order to alleviate the burden of server and bring users friendly experience, the technology of Ajax is also applied in the presentation layer design to refresh the local page.VS2010 bringing Linq to Sql database access technology is used in the design of data layer, it can automatically map data-tables into entity class,and C#code can be translated into SQL statement. Perform a search and don't write database connection statement. Handler processing program is used in the business logic layer,in order to accelerate processin speed.This thesis firstly describes the research background and significance,in order to have a comprehensive understanding of online-Exam system,and then sums up the system functional requirements,gives the system's data model and function model,and draw the main use case model,then gives the system's design idea and design target.The on-line Examination system is designed in detail,including the design of function module,database and architecture of the system.System's implementation is given lastly.This system has been running on the campus of Chengdu University of Technoloy, the actual application shows that the online-Examination system realizes the design goal, and the application effect is good. Especially, The use of the activation code can effectively avoid the piracy and safeguard the interests of the publishers and authors.
