Converting relational databases into object relational databases [PDF]
The Journal of Object Technology, 2010 This paper proposes an approach for migrating existing Relational DataBases (RDBs) into Object-Relational DataBases (ORDBs). The approach is superior to existing proposals as it can generate not only the target schema but also the data instances.

Getting Along with Relational Databases
Journal of the Text Encoding Initiative, 2022 Both relational databases (RDBs) and XML have strengths and weaknesses as data storage and modeling systems. Most researchers working with historical and literary data in the humanities would argue for the superiority of XML, since it allows unlimited ...

Object-oriented querying of existing relational databases [PDF]
, 1993 In this paper, we present algorithms which allow an object-oriented querying of existing relational databases. Our goal is to provide an improved query interface for relational systems with better query facilities than SQL.

Performance of Graph and Relational Databases in Complex Queries
Applied Sciences, 2022 In developing NoSQL databases, a major motivation is to achieve better efficient query performance compared with relational databases. The graph database is a NoSQL paradigm where navigation is based on links instead of joining tables.

Recommendations for Evolving Relational Databases [PDF]
Advanced Information Systems Engineering32nd International Conference, 2020 Relational databases play a central role in many information systems. Their schemas contain structural and behavioral entity descriptions. Databases must continuously be adapted to new requirements of a world in constant change while: (1) relational database management systems (RDBMS) do not allow inconsistencies in the schema; (2) stored procedure ...

A Blind Reversible Robust Watermarking Scheme for Relational Databases [PDF]
The Scientific World Journal, 2013 Protecting the ownership and controlling the copies of digital data have become very important issues in Internet-based applications. Reversible watermark technology allows the distortion-free recovery of relational databases after the embedded watermark

RELATIONAL ASPECTS OF RELATIONAL DATABASE DEPENDENCIES [PDF]
Bulletin of informatics and cybernetics, 2000 Summary: This paper presents a relational treatment of inference rules for functional and multivalued dependencies in relational databases, to show the soundness and the completeness of the inference rules in Dedekind categories, which also cover the fuzzy case.

Incomplete Information in Relational Databases
Journal of the ACM, 1984 ABSTRACT This paper concerns the semantics of Codd's relational model of data. Formulated are precise conditions that should be satisfied in a semantically meaningful extension of the usual relational operators, such as projection, selection, union, and join, from operators on relations to operators on tables with “null values” of various kinds ...

Relational Databases and Bell's Theorem [PDF]
In Search of Elegance in the Theory and Practice of Computation, 2012 Our aim in this paper is to point out a surprising formal connection, between two topics which seem on face value to have nothing to do with each other: relational database theory, and the study of non-locality and contextuality in the foundations of ...
