InterSect_DM: a hypertext data model based on OODBMS

Information and Software Technology, 1995
Abstract Using an object oriented database system as the information base to support a hypermedia system is currently a hot research topic in the human-computer interface design 1 . The important aspect of this research is the data model research of the hybrid system.

Functional Programming Formalisms for OODBMS Methods

1994
Two well-studied functional formalisms in the theory of programming languages are (1) applicative program schemas and (2) typed lambda calculi. We relate these programming formalisms to object-oriented databases (OODBs) and in particular to the description of methods.

Querying structured documents with hypertext links using OODBMS

Proceedings of the 1994 ACM European conference on Hypermedia technology - ECHT '94, 1994
Hierarchical logical structure and hypertext links are complementary and can be combined to build more powerful document management systems. Previous work exploits this complementarity for building better document processors, browsers and editing tools, but not for building sophisticated querying mechanisms. Querying in hypertext has been a requirement

Fine-grained sharing in a page server OODBMS

Proceedings of the 1994 ACM SIGMOD international conference on Management of data, 1994
For reasons of simplicity and communication efficiency, a number of existing object-oriented database management systems are based on page server architectures; data pages are their minimum unit of transfer and client caching. Despite their efficiency, page servers are often criticized as being too restrictive when it comes to concurrency, as existing ...

Databridge between RDBMS and OODBMS

1995
For applications, where some of used data is complex structured and some of data is simply structured, we can use an object-oriented DBMS but the processing simply structured data also will also use the overhead of OODBMS necessary for processing complex structured data. This decreases the efficiency of the processing. In this contribution, we describe

Implementing NRDR Using OO Database Management System (OODBMS)

2002
Motives for using a database management system (DBMS) to build a knowledge base system (KBS), include KBS's lack of ability to manage large sets of rules, to control concurrent access and to manage multiple knowledge bases simultaneously. In work, we build a KBS using a database management system DBMS for its schema evolution ability.

An introduction to schema versioning in OODBMS

Proceedings of 7th International Conference and Workshop on Database and Expert Systems Applications: DEXA 96, 2002
Object oriented database management systems (OODBMS) have enormous advantages in comparison to relational systems in modeling highly complex and dynamic application scenarios. Still they lack some flexibility which could help their promotion into widely spread industrial use.

Reasoning in Pervasive Environments: An Implementation of Concept Abduction with Mobile OODBMS

2009 IEEE/WIC/ACM International Joint Conference on Web Intelligence and Intelligent Agent Technology, 2009
The paper focuses on an implementation of concept abduction with an Object-oriented Database Management System (OODBMS). OWL-DL Knowledge Bases have been translated to an OO version to enable standard and non-standard inference services as queries over a DB suitable for handheld devices.

GENERIC APPROACH TO AUTOMATIC INDEX UPDATING IN OODBMS

Proceedings of the 11th International Conference on Enterprise Information, 2009
In this paper, we describe a robust approach to the problem of the automatic index updating, i.e. maintaining cohesion between data and indices. Introducing object-oriented notions (classes, inheritance, polymorphism, class methods, etc.) in databases allows defining more complex selection predicates; nevertheless, in order to facilitate selection ...

Adaptive, fine-grained sharing in a client-server OODBMS

ACM Transactions on Database Systems, 1997
For reasons of simplicity and communication efficiency, a number of existing object-oriented database management systems are based on page server architectures; data pages are their minimum unit of transfer and client caching. Despite their efficiency, page servers are often criticized as being too retrictive when it comes to concurrency, as existing ...
