Object-oriented querying of existing relational databases [PDF]
In this paper, we present algorithms which allow an object-oriented querying of existing relational databases. Our goal is to provide an improved query interface for relational systems with better query facilities than SQL.

Automatic Conversion of Relational Databases into Ontologies: A Comparative Analysis of Protégé Plug-ins Performances [PDF]
Constructing ontologies from relational databases is an active research topic in the Semantic Web domain. While conceptual mapping rules/principles of relational databases and ontology structures are being proposed, several software modules or plug-ins ...

Computing Multi-Relational Sufficient Statistics for Large Databases [PDF]
Databases contain information about which relationships do and do not hold among entities. To make this information accessible for statistical analysis requires computing sufficient statistics that combine information from different database tables. Such

DBRepo: a Semantic Digital Repository for Relational Databases
Data curation is a complex, multi-faceted task. While dedicated data stewards are starting to take care of these activities in close collaboration with researchers for many types of (usually file-based) data in many institutions, this is rarely yet the ...

Set-Oriented Mining for Association Rules in Relational Databases [PDF]
Describe set-oriented algorithms for mining association rules. Such algorithms imply performing multiple joins and may appear to be inherently less efficient than special-purpose algorithms. We develop new algorithms that can be expressed as SQL queries,
