Query Optimization by Indexing in the ODRA OODBMS
Annales UMCS, Informatica, 2009 We present features and samples of use of the index optimizer module which has been implemented and tested in the ODRA prototype system. The ODRA index implementation is based on linear hashing and works in a scope of a standalone database. The solution is adaptable to distributed environments in order to optimally utilize data grid computational ...

An Overview of Data Models of Object-Oriented DBMSs
Труды Института системного программирования РАН, 2018 Object-oriented DBMS theory is one of the most prospective areas of modern database theory, along with deductive and temporal DBMS. Nevertheless, a high variety of different approaches and absence of a uniform standard, both in theoretical OODBMS area ...

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

An Algorithm for the Analysis of Termination of Large Trigger Sets in an OODBMS
, 1995 In this paper we describe an algorithm for the analysis of termination of a large set of triggers in an OODBMS. It is quite clear that, if the trigger mechanism is of sufficient complexity, the problem is undecidable.

LOGICAL DATA INDEPENDENCE AND MODULARITY THROUGH VIEWS IN OODBMS
, 2008 Views in OODBMS are a concept which is heavily opted for by key database people but rather seldomly implemented in commercial systems. They are an important mechanism to modularize information systems and to gain ogical data independence.

Implementing Temporal Databases in Object-Oriented Systems
, 1997 We present a temporal object data model, query language and system that support temporal database applications. We then show how equivalent temporal constructs and operations could be provided in existing object-oriented database management systems ...

Augmenting the Performance of Existing OODBMS Benchmarks
International Journal of Computer Applications, 2012 Object oriented databases are widely popular for their complex data support and data relationships. Several object oriented database products are now coming to the market. Existing benchmarks are inadequate in testing the complex data support, concurrency control and performance of the database.
