Storing and querying ordered xml using a relational database system
- In SIGMOD
, 2002
"... XML is quickly becoming the de facto standard for data exchange over the Intemet. This is creating a new set of data management requirements involving XML, such as the need to store and query XML documents. Researchers have proposed using relational database systems to satisfy these requirements by ..."

Set-Oriented Production Rules in Relational Database Systems

"... We propose incorporating a production rules facility into a relational database system. Such a facility allows definition of database operations that are automatically executed whenever certain conditions are met. In keeping with the set-oriented approach of relational data manipulation languages, o ..."

Relational Database Systems
"... In this paper, we present a comprehensive approach for privacy preserving access control based on the notion of purpose. Purpose information associated with a given data element specifies the intended use of the data element, and our model allows multiple purposes to be associated with each data ele ..."
Abstract

purposes can be associated. We address this issue in the context of relational databases and propose four different labeling schemes, each providing a different granularity. In the paper we also propose an approach to representing purpose information, which results in very low storage overhead, and we
Buffer management in relational database systems
- ACM Transactions on Database Systems
, 1986
"... The hot-set model, characterizing the buffer requirements of relational queries, is presented. This model allows the system to determine the optimal buffer space to be allocated to a query; it can also be used by the query optimizer to derive efficient execution plans accounting for the available bu ..."

Gral: An Extensible Relational Database System for Geometric Applications
- PROC. OF THE 15TH INTL. CONF. ON VERY LARGE DATA BASES
, 1989
"... We describe the architecture of a relational database system that is extensible by user-defined data types and operations, including relation operations. The central concept is to use languages based on many-sorted algebra to represent queries as well as query execution plans. This leads to a simple ..."

Running Head: Integrating XML and Relational Database Systems
"... Abstract. Relational databases get more and more employed in order to store the content of a web site. At the same time, XML is fast emerging as the dominant standard at the hypertext level of web site management describing pages and links between them. Thus, the integration of XML with relational d ..."

Robust and Blind Watermarking of Relational Database Systems

Querying Ontologies in Relational Database Systems
- In Proc. of the DILS
, 2005
"... Abstract. In many areas of life science, such as biology and medicine, ontologies are nowadays commonly used to annotate objects of interest, such as biological samples, clinical pictures, or species in a standardized way. In these applications, an ontology is merely a structured vocabulary in the f ..."
