On supporting containment queries in relational database management systems
, 2001
"... Virtually all proposals for querying XML include a class of query we term “containment queries”. It is also clear that in the foreseeable future, a substantial amount of XML data will be stored in relational database systems. This raises the question of how to support these containment queries. The ..."

. The inverted list technology that underlies much of Information Retrieval is well-suited to these queries, but should we implement this technology (a) in a separate loosely-coupled IR engine, or (b) using the native tables and query execution machinery of the RDBMS? With option (b), more than twenty years
SQOWL: Type Inference in an RDBMS
"... Abstract. In this paper we describe a method to perform type inference over data stored in an RDBMS, where rules over the data are specified using OWL-DL. Since OWL-DL is an implementation of the Description Logic (DL) called SHOIN(D), we are in effect implementing a method for SHOIN(D) reasoning in ..."

Integrating KDD algorithms and RDBMS code
"... . In this paper we outline the design of a RDBMS that will provide the user with traditional quey capabilities as well as KDD queries. Our approach is not just another system which adds KDD capabilities, this design is aimed to integrate these KDD capabilities into RDBMS core. The approach also ..."

Parallel Cache Management of a RDBMS
, 1992
"... Increasing requirements such as higher transaction rates, shorter response times etc., make it necessary to parallelize existing database management systems and to implement them on multiprocessors. Shared memory multiprocessors are not arbitrarily scalable, and thus do not meet future requirements. ..."

Effective and Efficient Update of XML in RDBMS
"... Querying XML effectively and efficiently using declarative languages such as XQuery and XPath has been widely studied in both academic and industrial settings. Most RDBMS vendors now support XML as a native data type with SQL/XML and XQuery support over it. However, the problem of updating XML is st ..."

PIVOT and UNPIVOT: optimization and execution strategies in an RDBMS
- In: Proceedings of the 30th International Conference on Very Large Data Bases-Volume 30, 2004, 998–1009 Comput. Sci
"... PIVOT and UNPIVOT, two operators on tabular data that exchange rows and columns, enable data transformations useful in data modeling, data analysis, and data presentation. They can quite easily be implemented inside a query processor, much like select, project, and join. Such a design provides oppor ..."

Integrating IR and RDBMS Using Cooperative Indexing
- PROC. 18TH ACM SIGIR CONFERENCE ON RESEARCH AND DEVELOPMENT IN INFORMATION RETRIEVAL
, 1995
"... The full integration of information retrieval (IR) features into a database management system (DBMS) has long been recognized as both a significant goal and a challenging undertaking. By full integration we mean: i) support for document storage, indexing, retrieval, and update, ii) transaction seman ..."

Prototype implementations of system-level extensions to support cooperative indexing were evaluated with a modified version of Oracle Rdb. Our experimental findings validate the cooperative indexing scheme
