基于数据库建模的 DWG 文件数据挖掘模型研究

摘要

对设计院和设计部门积累的AutoCAD文件进行知识发现，具有非常重要的意义。而单纯的图形文件并不能有效的进行知识挖掘，因此如何将大量图纸中的信息提取出来是数据挖掘的基础和根本。给出一个基于数据库建模的体系结构模型，利用ActiveX Automation技术提取图形文件中包含的海量信息并存储到数据库中，将AutoCAD文件转换成为常用的数据库，在此基础上便可使用数据库的各种挖掘工具进行知识挖掘，从而为工程设计提供知识支持。%It is of great significance for knowledge discovery of AutoCAD files which accumulated by the design institute and design depart -ment.The Simple graphics files can not be effectively excavated of knowledge .Therefore, how to extract information from a large number of drawings is the basis and fundamental of data mining .Given an Architecture model based on database modeling , mass information of graphics files can be extracted and stored to the database based on ActiveX Automation Technology .This model converts the AutoCAD files into common databases , on this basis, a variety of database mining tools for knowledge mining can be used and provides knowledge support for engineering .
