自動命題系統(tǒng)的設(shè)計與實現(xiàn)
摘要：本文首先分析了自動命題系統(tǒng)在具體的教學(xué)活動過程中的實際需求，然后使用 MICROSOFT公司的 SQL Server作為后臺數(shù)據(jù)庫,設(shè)計數(shù)據(jù)庫，使用ODBC連接數(shù)據(jù)庫，使用 Borland公司的 Delphi開發(fā)工具，利用其提供的各種面向?qū)ο蟮拈_發(fā)工具,設(shè)計與實現(xiàn)了1個實際的自動命題系統(tǒng)，對其中的數(shù)據(jù)庫結(jié)構(gòu)設(shè)計以及各個主要模塊的實現(xiàn)進行了詳細(xì)的介紹。本系統(tǒng)可以從試題庫中自動的查找和組織出1些不同類型、不同難度的試題來組成1份合理的試卷。它采用的是利用試卷自動生成算法記錄試題的1組特征值，根據(jù)用戶提供的試卷題目類型、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)動態(tài)地抽象成邏輯數(shù)據(jù)，用以解決通用問題，線性的規(guī)劃出1份約束滿足的、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.
