Computer network examination data double-buffering method based on cloud architecture

Abstract

The invention relates to a computer network examination data double-buffering method based on a cloud architecture. The computer network examination data double-buffering method comprises the steps of acquiring test paper information by a client from a cloud-architecture network examination; establishing a data buffering file area on the client, and establishing a data storage system on a server; establishing a client buffering module and a server buffering module; generating a data buffering file by a client process data storage module from examination process data for storage; restoring the data to a computer of an examination terminal by a client process data restoring module; storing the examination process data into a data storage system of a remote server by a client process data storage module; and restoring the examination process data to the computer of the examination terminal by a server process data restoring module. The computer network examination data double-buffering method can prevent data loss in a temporary examination process caused by a client computer and furthermore prevents examination process data loss in computer change caused by computer collapse or other reasons. The computer network examination data double-buffering method has advantages of high speed of double-buffering, and high safety performance.

Description

technical field [0001] The invention relates to a network examination system, in particular to a network cloud examination system, which belongs to the field of computer technology. Background technique [0002] In order to meet the needs of more and more exams, improve the efficiency of exams, and ensure the correctness of exams, a cloud exam system based on cloud architecture has been developed. Cloud exam network exams greatly reduce the complexity and flexibility of organizing on-site exams, and can be extremely It is convenient for enterprises to organize various cross-regional examinations and tests at any time, even if users are not in the enterprise, they can take the specified examinations at any time. However, the test process data is unstable. The traditional test system generally has the problem that the test process data is easily lost due to the local storage method. When there are too many test questions, the test cannot be supported or a large amount of test ...

Problems solved by technology

However, the test process data is unstable. The traditional test system generally has the problem of test data loss due to the local storage method. When there are too many test questions, the test cannot be supported or a large amount of test data is lost during the test submission process.

If it is like the traditional way of saving the test process data to the local computer, there will be three risks that will cause the examinee's data to be unrecoverable: when the browser, the system crashes, or the computer is powered off, the file cannot be completely saved; when the computer is installed When the recovery card is deleted; when the computer cannot be restarted due to special circumstances
