A general approach to query flattening
J. van Ruth · University of Twente Research Information · 2005
The translation of queries from complex data models to simpler data models is a recurring theme in the construction of efficient data management systems. In this paper we propose a general framework to guide the translation from data models with nested types to a flat relational model (query flattening), and show how several instances of query flattening fit or do not fit in this pattern.
