XQuery on SQL Hosts
Relational database systems may be turned into efficient XML and XPath processors if the system is provided with a suitable relational tree encoding. This paper extends this relational XML processing stack and shows that an RDBMS can also serve as a highly efficient XQuery runtime environment. Our approach is purely relational: XQuery expressions are compiled into SQL code which operates on the...
متن کاملSQL, XQuery, and SPARQL
Does the world really need Yet Another Query Language? A new language for querying RDF, named SPARQL, is emerging from the W3C. Some observers say that the W3C's own XQuery is sufficient for querying RDF, at least in its XML incarnations, while others suggest that SQL is a more mature, widely-implemented language for querying tuples. This presentation explores these issues and positions the thr...
متن کاملIntegration of SQL and XQuery
F. Özcan D. Chamberlin K. Kulkarni J.-E. Michels Relational database systems have dominated the database industry for a quarter century. However, the advent of the Web has led to requirements for storage of new kinds of information in which the order of information is important and data structure can vary over time and from one document to another. These evolving requirements have given rise to...
متن کاملXQuery Translation to Sem-SQL
XML query translation is an inevitable step involved in using non-XML databases storing XML data. In this paper, we address the XQuery to Sem-SQL translation issue, part of the XML storage and retrieval using the Semantic Binary Object-Oriented Database System (Sem-ODB) project, by providing a high-level description of the translation scheme between XQuery and Sem-SQL. Our translation scheme ut...
متن کاملA Peformant XQuery to SQL Translator
We describe a largely complete and efficient XQuery to SQL translation for XML publishing. Our translation supports the entire XQuery language, except for functions, if statements and upwards navigation axes. The system has three important properties. First, it preserves the correct XQuery semantics. This is accomplished by first translating XQuery into core-XQuery, using a complete XQuery impl...
