Design And Implementation Of XX Bank Online Examination System Based On Web

In recent years,with the rapid development of network technology,the traditional examination mode canont adapt to the existence of many branches in different places.In the traditional examination mode,the Examination organization is not flexible,the transmission process is unsafe,the examination organization is single,the cost of manpower an d material resources is great,and the statistical analysis of achievements and test questions is difficult in the later stage.The existence of these problems restricts XX Bank's current idea of promoting the development of banks through informatioa technology,and hinders the application of big data to support the transformation and development of banks.Through the online examination system,the examination can be carried out simultaneously in different branches,and the data can be fully used to analyze and improve the efficiency of the examination work.Based on the characteristics of XX Bank Examination,this dissertation discusses the design and implementation of the system from various angles.The system is based on B/S architecture.The background database is implemented with SQL Server 2008 R2 and Visual Studio 2017 as development tools.The main work of this paper is as follows:1.based on the demand collected by XX Bank through seminars in the early stage,and combined with UML use case diagrams and use case tables,the system's function and performance requirements are analyzed in detail.2.on the basis of the acquired requirements,this dissertation designs the solution of XX Bant Online Examination System in detail,mainly giving its functional structure and related architecture.Architecture includes:related business processes,database structure,in which the meain database tables include user information table,user role table,test task table,system log table,column application table,ser rights table,privilege status table,desktop information table,Department table,test results table,test questions database,test information,column information tabte,etc.Functional structure includes practice and examination,ability evaluation,examination management,examination management and background management.3.Then,on the basis of the design instructions,the design of each functional module and database is given by using class diagram,sequence diagram and E-R diagram,and the specific implementation process of the functional module is given.4.Finally,the function test of the system is completed by using test cases.At the same time,the system performance test is carried out by Loadrunner tool,and the test report is given.The system has passed the test,and has been deployed in the office network of XX Bank.After three months of operation,the system runs steadily.It can ensure that more than 400 people in 10 branches carry out online examination at the same time,basically meeting the requirements of XX Bank online examination.At the same time,the system can provide intuitive and accurate data for human resources departments and business line management departments to manage test questions database,test results analysis,and statistical analysis of the difficulty degree of test questions,and improve the ability of examination organizers to organize in-line examinations.
