A solution to this drawback is to use a native XML database. This paper discusses current state-of-the-art database solution for XML data and shows that native ...

There are generally two approaches to providing database support for XML data management: extended-relational approach and native XML approach. In the extended- ...

The navigational processing techniques, built on top of the native storage systems, match the pattern tree by traversing the XML tree. Some navigational ...

In this paper, we use a new structure, called Evaluation Tree, to execute QTPs. We also extend our method to support QTPs having logical operators OR, XOR, and ...

Dec 11, 2014 · In this paper, we present MPX, a multiversion concurrency control protocol for XML documents, which is designed for synchronizing concurrent ...

In this paper, I summarize my research on optimizing XML queries. This work has two components: the first component is the definition of a logical algebra ...

In this paper, we attempt to fill this gap by integrat- ing all existing tree-pattern query processing methods over stored XML data in a unified environment. We ...

In this paper we overcome this entire problem by implementing a TreeMatch algorithm [3]. XML query processing was considered by Timber. [15] and Lore DBMS [11].

Our approach performs heuristic-based algebraic transformations on XPath queries, represented as PAT algebraic expressions, to achieve query optimization. This ...

We have compared competing concepts in various system layers and iteratively found salient solutions which drastically improved the overall XDBMS performance.
