使用XML实现DXF图形文件的数据挖掘

Data Mining Using XML File Transformed from DXF File

根据DXF图形文件的特点,设计了XML模式,确定了XML文件格式。将DXF图形文件转换成XML文件,于是对DXF文件的数据挖掘变成了对XML文件的数据挖掘。确定了数据挖掘的体系结构,构建了数据仓库中的元数据。从XML文件中提取几何形体,并确定其位置关系,形成了工程图形数据仓库。

According to the features of DXF file, the XML Schema is designed and the format of XML file is determined. Then DXF file can be transformed to XML file, thus the data mining for DXF files becomes for XML files. The system architecture and the meta data in data warehouse are determined. An engineering graphic data warehouse is generated contained geometric shape data and related positional data, which are extracted from XML file.
