C語言上機(jī)考試系統(tǒng)
      
摘  要：基于C/S的C語言上機(jī)考試系統(tǒng)是典型的網(wǎng)絡(luò)考試系統(tǒng)之1，具有可靠性、壽命長、可行性、安全性的優(yōu)點(diǎn)。系統(tǒng)實(shí)現(xiàn)主要包客戶端、服務(wù)器端的開發(fā)和后臺(tái)數(shù)據(jù)庫的建立和維護(hù)。前者要求應(yīng)用程序功能完備，易使用的特點(diǎn)。后者則要求建立起數(shù)據(jù)1致性和完備性強(qiáng)，數(shù)據(jù)安全性好的數(shù)據(jù)庫。
在本考試系統(tǒng)中本人重點(diǎn)完成了前臺(tái)客戶端的開發(fā)，主要開發(fā)功能有：管理員登錄、考生登陸、選擇考試、選題做答、成績查尋、考試記時(shí)、數(shù)據(jù)庫維護(hù)等。界面簡潔，功能完備。經(jīng)過分析，我使用了Delphi7開發(fā)工具和Access數(shù)據(jù)庫開發(fā)工具。通過ADO控件訪問數(shù)據(jù)庫。
本系統(tǒng)的開發(fā)注重工程的實(shí)踐性，實(shí)用性，通過本系統(tǒng)的開發(fā)不但實(shí)現(xiàn)了系統(tǒng)實(shí)用性、靈活性、可靠性的要求而且讓用戶可全面掌握利用Delphi開發(fā)數(shù)據(jù)庫應(yīng)用程序的方法和步驟以及數(shù)據(jù)庫設(shè)計(jì)的原則。

C language hands-on test system
 
Abstract:  Based on C/Ss C language hands-on test system is one of typical network test systems, has the reliability, the life long, the feasibility, the secure merit. System realization main package client side, server end development and backstage database establishment and maintenance. The former request application procedure function is complete, easy to use characteristic. The latter requests to establish the data uniformity and complete, the data security good database.
Myself have completed the onstage client side development with emphasis in this test system, mainly develops the function to include: The manager registers, the examinee lands, the choice test, the selected topic does answers, the result search, the test time, the database maintenance and so on. The contact surface is succinct, the function is complete. After the analysis, I have used Delphi7 development kit and the Access database development kit. Controls the visit database through ADO.
Not only this system development attention project practicality, the usability, realized the system usability, the flexibility through this system development, the reliable request moreover has let the user be possible to grasp comprehensively uses the Delphi development database application procedure the method and the step as well as the database design principle.

Key words:   C language hands-on test system, client side, Delphi7.0.
