摘要
针对异构数据格式转换问题,提出一种基于上下文无关文法(Context-Free LanguageCFG)的数据格式转换描述语言(Data Format Transformation Language DFTL)。DFTL采用XMLSchema描述数据的逻辑结构,定义扩展标记描述数据解析和模型映射规则。实验研究证明,基于DFTL可实现不同类型的数据格式到XML格式的转换,为异构数据访问提供统一的XML视图。
Presents a context- free grammar, Data Format Transformation Language （DFTL）, to take transformation between data with heterogeneous formats. The logical structure of data is described by XML Schema in DFTL, and the parsing and mapping rules of data are defined on the basis of extended markups. Experimental results show that it is possible to transform data with various formats to the data in XML by DFTL, thus a unified XML-view becomes true for the accession of data with heterogeneous formats.
