1、网络考试系统外文翻译 外文资料： Regard along with the network technology daily popularization and the information construction, now the school generally all compounded the test safe monitoring equipment, and has built the management information system in this foundation, to information construction positive impetu

2、s function. But has the software construction in the practical work to fall behind the phenomenon which constructs to the hardware, for example, the education administration level also pauses to examinees inspection in the traditional test pattern, not only the efficiency is low, moreover also has m

3、any malpractices, creates the information resource the waste. Test non- paper, network, not only can effectively reduce the correlation personnels work load, the better use computer and the network superiority, enhances the working efficiency, also can fairly cause the test, to be fair. Based on thi

4、s kind of demand, we developed set of performance stably for the test design, safe have been reliable the network which, the ease of operation was allowed to satisfy massively simultaneously uses to take a test the system. Causes the test the security, fairness, fair greatly to enhance. After this s

5、ystem actual movement uses, effect good, not only greatly advanced the test information construction advancement, moreover causes the school to examinees inspection more scientific, air, fair, to be highly effective and the network. The network test system should be able to satisfy the massive exami

6、nees in any place, any time all can participate in the test, and automatic judgment result. Through to the test service demand multianalysis, the main function which this system should provide as follows: 1) The examinee may on-line carry on the test, after the test had finished by computer automati

7、c judgment score, and the recording result, the examinee also may examine the standard answer. If the test time, the system automatic prompt completes an assignment and stops doing answers. 2) The teacher may on-line establish the revision question bank, revises the examinee individual material, and

8、 monitors the examination place situation and so on. 3) the manager may on-line establish reference material and so on the examinee, teacher, the verification question bank, arranges the examinee to take a test, revises the examinee and the examination place condition, inquires the examinee to take

9、a test the result, monitors the examination place situation as well as the 网络考试系统外文翻译 establishment test project with tests the test question number and so on. Moreover for the guarantee test fair, is fair, the examination paper test question stochastically extracts by the computer from the question

10、 bank. For strictly will cease the test to cheat the behavior, the system later is best also should provide the function which the fingerprint confirmation will register. Its main flow is: After the user basis is authorized registers, the system basis user jurisdiction difference, establishes the co

11、rresponding operation. After the train attendant registers may carry on the test, operation and so on examination result and standard answer； After the teacher registers may carry on revises operation and so on examinees individual material, revision question bank, revision user password as well as

12、monitoring test situation； After the manager registers besides has teachers all functions, but also may carry on the verification question bank (only has verified question bank only then to be allowed to carry on test),establishment operation and so on test time, inquiry, printing test result. Also

13、may establish following several items: Test workstation: Carries on the test to the examinee the customer end procedure. Mainly provided has carried on according to the system disposition stochastically sets the topic of a composition, the confirmation registers, test function and so on time prompt,

14、 automatic judgment result, examination test result as well as standard answer. Test workstation divides into the customer end procedure and the Web way in the realization way, former allows the examinee (support touches screen test pattern) through the customer end procedure the way to carry on the

15、 test, latter allows the examinee to carry on the test through the test special-purpose network. The test establishes the workstation: Carries on the establishment tote test service the customer end procedure. Mainly provided the revision question bank, the verification question bank, revised the ex

16、aminee material, establishes the examinee/examination place condition, the inquiry/printing test result, the question bank inducts/derives function and so on function as well as monitoring test situation. Test application server: Network on-line test system application server. Mainly has realized th

17、e data cushion and the test service logic seal and duplicate uses the function, is takes a test the workstation, the test establishes the workstation and the database server connection. Has provided the rich connection using the server, may increase or the reduced service rule through the module way

18、, considered later will take a test the service promotion, also should reserve the new test type connection 网络考试系统外文翻译 using the server level, will cause later the system to expand conveniently. Moreover, for guarantee test effectiveness, using server support hot backup database server pattern, name

19、ly if presently is using the database server breaks down, then in the system disposition reserve database server automatic cutover for the current database server, all these is does not know in the user with in the intervention situation carries on. Through application server level effectiveness, tr

20、uly caused the test service to achieve the use easily, the function formidable, the performances table, the modular degree was strong, has satisfied the new time to an information construction higher request. Furthermore, considered the system the stability with carries out the efficiency, in the an

21、alysis network configuration foundation, the system later might select distributional three C/S and B/S will mix with the overhead construction method, namely: The examinee if miscarries on the test in this section, may choose the C/S structure to touch the screen test and the examination site test

22、pattern； If the examinee is carries on the test in the outside areas, may choose the B/S structure the examination site test pattern. The network on-line test system needs to carry on the data through the network the transmission, therefore applies the server, the Web server and the database server

23、security must from the system design time carries on the plan. We might use below the security measure: 1) In stalls the reliable firewall, carries on the effective containment to the exterior malicious attack. 2) The server (including applies server, database server and the Web server) the hard dis

24、k district transformation is the NTFS form, open sure sportive jurisdiction according to the different demand for the user. 3) May write the essential code the DLL module, not only streng the need the security, simultaneously also caused the system the modular degree to strengthen, enhanced the syst

25、em performance. 4) May carry on two times of encryptions in the database to the essential data. 5) 2,000 data backups with restores the function using SQL the SERVER, guarantees the database information the integrity and the security. The current software quite popular system structural model mainly has: C/S structural model and B/S structural model. These two kinds of structures may divide into two with the multilayered overhead con saturation, the main difference lies in
