Design And Development Of Automatic Examination System

In recent years, with the fast development of our national economy,the occupation qualification examination is appeared in some business in order to standardize our employment market.There are many kind of exam emerged, it must come into inefficient and resource wasting if we still use traditional way in these exam. The increasing in exam items result in the cost of human resource and material resources are increasing. Human resource selecting are restricted by inefficient exam. The traditional way is inapplicable now, so the innovation is imperative.It is a kind of effective reform way to lead computer management into and have an examination." System of Comprehensive examination of civil servant's ability of computer application " is designed to be a general examination system.The system can be used in many fields which includ the enterprises and institutions , school , scientific research institution.The prospect of the system is very wide. This system is developed with Delphi 7 on windows 2000 operation platform with visual programming technology,which is not nonly a advanced programming language with fine interface but a object oriented.Delphi 7 is the newest client/server mode application program tool,made by Borland C.O.It is applicable with not only the developing of the mode which is widly built but he needs of developing on Web.At the same time ,it is support serials in operation platform,with the ability of developing program from one operation platform to another one.The programming language in Delphi 7 ,which is not the sample language of the forth kind,but an anvanced architectural programming language. " System of Comprehensive examination of civil servant's ability of computer application" is constitute by 6 subsystems, respectively is: management of database of questions , management of examination paper, management of the information of examinee, management of the information of examine, examining and grade subsystem. This text expatiate the exploiture process of "System of Comprehensive examination of civil servant's ability of computer application",the whole exploiture process include three portion: the phase of system analysis, the phase of system design, the phase of system implementing. It give the exhaustive introduce for every portion, include the goal, effect and result of phase implementing, etc. it give the process of exam system exploiture, the process of structure, and form the mature and exercisable client system finally. The key technology that the system adopts while developing are Object Oriented Programming in Delphi and COM programming technology. Object Oriented Programming run through the development of the system.Object Oriented Programming pay attention to reuse of the programming code.Class abstract corresponding realistic thing in program simplified the programming content greatly.The definitions of class and object in the program make the content of the program more abstract and approach the real things even more, Object Oriented Programming technology enable us to solve the problem more ocularly . The application in the examination system of COM programming technology mainly reflect on OLE (Object Linking and Embeding ) technology.COM technology establish mutual standard of communication between different COM applications , this make different COM application have mutual possibility of communication.This is a foundation of OLE technology.Object Linking and Embeding technology as a ripe application of the COM technology have offered one to establish and compound the file information of coming from different application program with a powerful method.The Object can be almost all types of information such as characters , location picture , vector figure, even the sound note and video film editing,etc.. Subjective question in the examination adopted OLE technology in the examination system.
