Storing and Querying XML Data in Object-Relational DBMSs
- In EDBT Workshops
, 2002
"... Abstract. As the popularity of eXtensible Markup Language (XML) continues to increase at an astonishing pace, data management systems for storing and querying large repositories of XML data are urgently needed. In this paper, we investigate an Object-Relational DBMS (ORDBMS) for storing and querying ..."

Implementation of Object-Relational DBMSs in a Relational Database Course
"... Abstract: Object-relational DBMS was gradually added as a new topic to the author’s database course in response to the rapid changes in DBMS technology in the real world. Implementation of ORDBMS technology in a traditional relational database course had significant impacts on the database curriculu ..."

Active Object-Relational Mediators
- In Proc. of CoopIS
, 1996
"... This paper describes an active object-oriented mediator for the enforcement of global consistency between relational legacy databases. We discuss the problem of integrating several local relational systems into a federated system by the usage of an object-oriented mediator system. We explore how rel ..."

relational DBMSs can be enhanced to signal local updates that may violate global constraints without sacrificing too much autonomy and present a database gateway for detection, logging and signalling. We show how the gateway is embedded into the architecture of an object-relational mediator system. We give a

Prefetching Based on the mpe-Level Access Pattern in Object-Relational DBMSs
"... songiy @ drexel.edu Prefetching is an effective method for minimizing the number of round-trips between the client and the server in database management systems. In this paper; we propose new notions of the typelevel access locality and the type-level access pattern. We also formally define the noti ..."

pattern is a pattern of attributes that are referenced in accessing the objects. Existing prefetching methods are based on object-level or page-level access patterns, which consist of object-ids or page-ids of the objects accessed. Howevel; the drawback of these methods
Storing Linked XML documents in Object-Relational DBMS
- Journal of Computing and Information Technology
, 2006
"... Currently, several researchers have proposed mapping both structure and constraints of XML documents to an object-relational database ORDB. However, these researches cannot be conducted because of the lim-ited range of constraints in available object-relational DBMSs. We therefore propose mapping ru ..."

Object-Relational Databases on the WWW: Design and Implementation Issues
"... The current generation of object-relational databases can support complex data types including multimedia types. This paper describes some of the challenges and opportunities facing OR-DBMS technology in the web environment. The PREDAT OR project at Cornell is actively exploring some of these issues ..."

of these issues. We present initial directions that suggest that several standard system design and implementation decisions need to be reconsidered. 1 Introduction Current object-relational database systems (OR-DBMSs) support complex data types like images, audio, documents, etc. Not only can this data
A Comparative Evaluation of the Major Commercial Object and Object-Relational DBMSs: GemStone, O_2, Objectivity/DB, ObjectStore, VERSANT ODBMS, Illustra, Odapter and UniSQL
, 1996
"... In this paper, a review of some of the major ODBMSs (GemStone, O_2, Objectivity/DB, ObjectStore and VERSANT) and Object-Relational DBMSs (Illustra, Odapter and UniSQL) is presented. The major architectural components are described and various features, such as support for relationships, schema evolu ..."

Object-relational Queries into Multidimensional Databases with the Active Data Repository
, 1999

As computational power and storage capacity increase, processing and analyzing large volumes of multi-dimensional datasets play an increasingly important role in many domains of scientific research. Scientific applications that make use of very large scientific datasets have several important charac ..."

characteristics: datasets consist of complex data and are usually multi-dimensional; applications usually retrieve a subset of all the data available in the dataset; various applicationspecific operations are performed on the data items retrieved. Such applications can be supported by object-relational database
