Analysis And Design Of Online Examination System Based On ASP

Caused the examination along with the Internet technology development the technical method and the carrier has had the revolutionary change, the Internet openness, the distributed characteristic and causes the examination based on Internet huge computation ability to break through the time and the spatial limit, took a examation the system based on the Internet net on to become one of people's research hot spots. And along with the standardized examination daily popularization, in all levels of each kind of examination examation more and more many used on the net to take a examination system. With the extensive application of on-line examination, teaching resources transmitted to the individual or groups of different geographic locations possible. The development high efficiency on-line examination system, provides nimbly for the student, is convenient, the science individuality study way has become inevitably.School education, the Internet is gradually entering the campus, the schools have established a campus network, which will provide a new means of teaching-school education network.The network education not only promoted the education thought, the education method and the education method renewal, simultaneously has also provided the corresponding network platform for the on-line examation.Online education examination as an indispensable component of the network is an important part of education network.Examinations of students through online distance learning teachers can evaluate and understand the children's learning, to provide a basis for improving teaching, Available through the Internet and students can exam their understanding of the content of the picture, enhance interest in learning; Standardization of computer teachers also increased the efficiency. However, the majority of the examination form of the traditional "a examation, a T" model, teachers need to spend Proposition and scoring a lot of time, the school should spend more resources (a large quantity of paper and printing papers, the officers kept confidential, transportation, etc.). This traditional pattern has seriously lagged the new teaching way, the research and the development high efficiency on-line examation system imperative.This paper based on B / S three-tier structure of the development of methods, introduced the ASP and SQL server 2000 technology, the development of online examation system. The system fully reflects the openness and efficient design, For example: The question bank may carry on maintenance as necessary and so on increase, deletion, revision; Users can easily download the necessary competence. System module functions, and easy to operate, so the examination process has become convenient, efficient, quick, it has lowered the cost of the examination. Has a better understanding for the user to ASP, also favor uses the ASP technology well, this article introduced the ASP technology principle of work and it's the movement environment. At the same time, more details on the SQL server 2000 database of some of the basic knowledge, technology and database ASP technology is an effective combination. ASP examation for the rapid production of the homepage, the web tools Dreamweaver MX 2004. On this basis, the completion of a network of online examination system design, this paper introduces in detail the preparations of the system development, system design and the function of each module, system and the realization of detailed design.1,The main content of this paper :The online research needs of the examination system engineering analysis.Studies in the on-line examation system the question bank management (input, revision, inquiry, deletion and so on), the examination paper management (group volume, maintenance examination paper), the examation management (including examation, examines examation papers, looks up result and examation analysis and so on), the system movement diary management, the safety control and so on each function.Studies the on-line examation system and the software realization system structure.Studies the on-line examation system the group volume strategy (science judgment topic, list selected topic, multiple selected topics, fills up topic).The online examation system research program and examination results and other important data back up.2,System design1) Group volume functional designAutomatic Paper: Manager automatically imported through the browser component of examination papers in the corresponding database. The system automatically create a randomly selected to meet the requirements of the examination questions. Artificial Paper : If because the condition limit cannot take a examation in the network, the teacher also may also have the examation question the prompt, the problem solving process, the topic examination paper typesetting printing, carries on the conventional examation The examation way is flexible, may not the time and the spatial limit.Any one with the students in the computer networking for the Internet2) On-line examationStudents choosing to sit out the subjects and papers in the HTML browser with the papers show. Candidates can start online examation, a student must paper submitted within the stipulated time, the system automatically rolling.3) Marking OnlineAfter the examinee completes an assignment, the system automatically will examine examation papers (objective topic), might produce the result and the standard answer, and will store the result the examinee result database.4) Takes a examation the result inquiryAfter the student registers, chooses oneself has examationed subject, then may assign out this examination paper, demonstrates this examination paper the content, the standard answer, student's answer paper recording situation and so on.5) Question bank managementIncluding manager of the bank increase, modify, and delete query operation.6) User ManagementSet user jurisdiction, including average consumer and manager user.7) The examination place control System control examation time, guards against renovates, the examation result automatic production, the multi-purpose inquiry.3,Database designRealizes the on-line examation system functional need corresponding database, this database mainly by user information table, question bank information table, examation information table, waiting through the project information table, the examation result information table and so on five tables compose.1) The information to users, said the basic user information, the table contains the following fields: examination, the candidates names, passwords, professional, and other branches.2) The information database used to store the item. The list contains the following fields: subject numbers, the stem questions, choice, the correct answer the questions whether the markings were chosen.3) Examination papers said the information was used to store some basic information. The list contains the following field: examination number, the quantity and variety of subject scores and examination time, the effective date of the examination, verification and so on.4) Waited for through the project information table is the system establishes the examation information by the manager, after leadership verification through examation. Includes the following field: waiting through project category, serial number, verification, verification date, whether passes.5) Examination results are used to store the information of the examination results. The list contains the following field: the various candidates, examination information, examination results.4,Network security questionThe system is an Internet-based IIS systems, Internet-based network security system is a very important issue. The main issue of network security systems to achieve the following aspects:1)Depends upon operating system Windows 2,000 and large-scale database SQL server 2000 jurisdiction establishes controls.2) The establishment of the system user registration system. All authorized users to install and competence in the use of computers which, a total of two types of users: common users and system administrators.3) Guarantees the system using the present quite mature firewall technology the security.
