Paper Abstract:
|
Many applications require efficient storage of XML data as well as relational data. Thus, the ability to manage both kinds of data becomes essential for organizations. One of the alternatives consists of mapping the structure of XML documents to a relational schema, but it becomes complex since XML documents can have different structures, even when representing data from a common domain. In this case, in addition to mapping the structure and the XML data to relations, it is also required to translate XML queries to SQL. We propose a set of rules to translate XQuery queries to equivalent SQL queries, more specifically in the step of converting XQuery algebra to relational algebra. |
