自動(dòng)命題系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)
摘要：本文首先分析了自動(dòng)命題系統(tǒng)在具體的教學(xué)活動(dòng)過(guò)程中的實(shí)際需求，然后使用 MICROSOFT公司的 SQL Server作為后臺(tái)數(shù)據(jù)庫(kù),設(shè)計(jì)數(shù)據(jù)庫(kù)，使用ODBC連接數(shù)據(jù)庫(kù)，使用 Borland公司的 Delphi開(kāi)發(fā)工具，利用其提供的各種面向?qū)ο蟮拈_(kāi)發(fā)工具,設(shè)計(jì)與實(shí)現(xiàn)了1個(gè)實(shí)際的自動(dòng)命題系統(tǒng)，對(duì)其中的數(shù)據(jù)庫(kù)結(jié)構(gòu)設(shè)計(jì)以及各個(gè)主要模塊的實(shí)現(xiàn)進(jìn)行了詳細(xì)的介紹。本系統(tǒng)可以從試題庫(kù)中自動(dòng)的查找和組織出1些不同類(lèi)型、不同難度的試題來(lái)組成1份合理的試卷。它采用的是利用試卷自動(dòng)生成算法記錄試題的1組特征值，根據(jù)用戶(hù)提供的試卷題目類(lèi)型、難易程度等條件，借助于系統(tǒng)中的1系列數(shù)據(jù)文件，使具體課程的相關(guān)數(shù)據(jù)動(dòng)態(tài)地抽象成邏輯數(shù)據(jù)，用以解決通用問(wèn)題，線(xiàn)性的規(guī)劃出1份約束滿(mǎn)足的、合理的試卷。

Design for implementation of automatic proposition system
Abstract： This paper analyses the actual demand of auto-production for automatic proposition system in the course of concrete teaching activity at first. Then Uses MICROSOFT Corporation dish SQL Server to take the backstage database design database, uses Borland Corporation dish Delphi development kit, uses each kind of object-oriented development labor which it provides ,to use the ODBC connection database, it designs and realizes a automatic proposition system. First, it explains the design for the database structure, then introduces the detailed one to the realization of each main module among them. It can automatically find and organize a certain number of test questions in various types with different degrees of difficulty in the database to form a reasonable test paper. The method is that the Characteristic properties of test questions are recorded firstly, and then according to user’s demands in type,difficulty, etc ,by changing related data of the course to logical ones a suitable and satisfied to restrain test paper of universal property on the basis of series of data files is linearly programmed.
Key words: self-paper-seting database proposition system.
