The technique described how the  various de¿nitions in a given XML DTD, such as elements, attributes,  parent-child relationships, ID-IDREF(s) attributes, and collection types  can be mapped to entities and relationships. It described how to handle  the Union types that are not present in relational model, and it showed  that the XML¿s ordered data model can be e¿ciently supported by the  unordered relational data model\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659240058\"\u003e\u003ch3\u003eMapping\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659240058","offer_id":39487798935645,"sku":"9783659240058","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5995c92a-f8ce-4ccc-b824-063fb2e7d23c.jpg?v=1774679229","url":"https:\/\/shop.autorenwelt.de\/products\/mapping-xml-dtds-to-relational-schema-von-abd-el-aziz-ahmed-abd-el-aziz","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
