In order to efficiently determine structural relationships among XML elements and to avoid re-labeling for updates, much research about labeling schemes has been conducted, recentl...
In the paper we discuss the problem of data integration in a P2P environment. In such setting each peer stores schema of its local data, mappings between the schema and schemas of...
In [3], we introduced a framework for querying and updating probabilistic information over unordered labeled trees, the probabilistic tree model. The data model is based on trees ...
XML data is often modeled as node-labeled trees. In a structure-generic relational storage scheme, the structure of the XML data is shredded into pieces of a generic type, such as...
Database techniques to store, query and manipulate data that contains uncertainty receives increasing research interest. Such UDBMSs can be classified according to their underlyin...
