Description: There is a large amount of data on the web organized in databases; thus when queries are posed against these databases, it is important to answer them as efficiently as possible. The most used approach to accomplish this goal is based on rules that do not consider the semantic information, i.e., the integrity constraints. On the other hand, semantic query optimization take advantage of this information, accomplishing the initial goal.XQuery is a query language designed to be applicable across all types of XML data sources, including both databases and documents. In this thesis we present a study of the problems of structural and semantic query optimization for XML, using XQuery, and we propose solutions to these problems.
