We implement a filesystem in userspace backed by the MonetDB/XQuery system, a well-known relational database system, which integrates the Pathfinder XQuery compiler [5] and the Mon-etDB kernel [4] . ...
This paper introduces a Ph.D. project focused on the question in how far the tree-awareness of recent RDBMSs can be used to, once again, try to implement filesystems using database technology. ...

There are two approaches to implementing parametric databases using XML: 1) a native XML database with XQuery engine, and 2) an XML storage with a temporal query language. ...
The parametric data model captures an object in terms of a single tuple. This feature eliminates unnecessary self-join operations to combine tuples scattered in a temporal relation. ...
Implemented temporal database systems are broadly categorized into two groups: temporal database systems over relational database systems and temporal database systems over object-oriented database systems ...

Our main focus is on the Pathfinder XQuery compiler, a full reference implementation of a purely relational XQuery processor. ...
Given the tremendous versatility of relational database implementations toward a wide range of database problems, it seems only natural to consider them as backends for XML data processing. ...
Since relational database systems are, by far, the most scalable and efficient data processors currently available, we want to implement XQuery functionality on relational foundations wherever possible ...
