Examples
- Document type definition ( dtd ) should be defined before building urban geographic information system based on xml
要建立基于xml的城市地理信息系统，首先要定义它的文档类型定义( documenttypedefinition ， dtd ) 。 - In order to manipulate the data among the databases each other it is required to comply with the uniform xml documents of document type definition ( dtd ) . there are three aspects are involved in this model mainly
数据库之间的数据应遵守统一的文挡类型定义（ adocumenttypedefinition , dtd ）的xml文挡进行交换，以有利于互操作。 - Dkow is capable of modeling and reasoning static domain knowledge , including domain structures , concepts and properties of the concepts , and the relations among concepts , etc . in order to apply the power of domain ontology to express the semantic information of web data , the author presents an algorithm named dtd generating from domain ontology ( dtdgdo ) that maps a given ontology to a document type definition ( dtd ) based on the transformation rules
作者提出了一种基于领域本体的web数据语义信息的表示方法，设计了dkow构建的形式化领域本体到相应dtd的生成算法dtdgdo 。作者在属性定义方面增强了现有ecfgs方法对dtd模型的定义，设计了生成算法dtdgdo的三类转换规则：重组规则、变换规则、基数规则。 - In technique , the key is to implement the exchange of the mode of relational database and xml . that is mapping between them . the data structure is denoted by xml document type definition ( dtd ) and the content is denoted by xml document . so that keep consistent with each other in during of exchanging
在技术上，关键是实现关系数据库与xml模式的互相转换，即两者之间的映射。数据库存储的元数据由xmldtd ( documenttypedefinition )表示，而数据信息由xml文档表示。这样，两种模式在互相转换的过程中就可达到一致性。
