Experimental Teaching Management System Based On ASP.NET In Higher Vocational Colleges

In recent years,Chinese Government and Vocational Colleges provided adequate fund and support to laboratory construction,hence the number of laboratory equipment has been booming.At the same time,the proportion of practical courses,the number of experimenter and the frequency which the devices are used have increased drastically.However,due to the low attention paid to the information construction of experimental teaching in vocational colleges,the information management of experimental teaching lags behind relatively.Aiming at adapt to the "Internet + vocational education",it is necessary an experimental teaching management system for in higher vocational colleges.The experimental teaching management system adopts B/S framework and ASP.NET,and uses MongoDB as its system database.Meanwhile,the data synchronization subsystem is designed based on MongoDB replication,which uses NTP protocol to unify the time of the device,and implements synchronize data bidirectionally by analyzing the incremental data in oplog.The system can ensure the offline operation of users in emergency cases such as network disconnection.For verify the correctness of the system,we did some tests of the function,performance and the data synchronization.The system implements main functions including information management,experimental project release,experimental report submission and review,etc.The reliability and stability of the system are verified by the system response time,concurrency test,and data synchronization test between the local server and the central server.
