Construction of relations in relational databases

ACM Transactions on Database Systems, 1980
Using a nonprocedural language for query formulation requires certain automatization of a query answering process. Given a query for creation of a new relation, the problem is to find an efficient procedure which produces this relation from a given relational database. We concentrate upon sequences of join operations which losslessly produce a relation

Fingerprinting relational databases

Proceedings of the 2006 ACM symposium on Applied computing, 2006
In this paper, we propose a fingerprinting solution to protect valuable numeric relational data from illegal duplications and redistributions. We introduce a twice-embedding scheme. In the first embedding process, we embed a unique fingerprint to identify each recipient to whom the relational data is distributed.

MARC and relational databases

The Electronic Library, 1993
MARC format is a well‐established syntax for transmitting bibliographic records between heterogeneous computer systems. On the other hand, relational databases are the leading technology for the design of the computer systems. Unfortunately, there seem to be some incompatibilities between the two.

Converting Temporal Relational Database into Temporal Object Relational Database

2017
This paper presents an approach for migrating existing temporal relational database (TRDB), into temporal object relational database (TORDB). This is done by enhancing a representation of a varying time database’s structure, in order to make hidden semantic explicit.

Relational Database Modeling and Database Design

2003
A good database is the bedrock on which you can create a good application. To create a sound database, you need to learn conceptual modeling skills. Database modeling and design are areas in which not all database administrators (DBAs) are uniformly proficient.

Relational databases

1990
Publisher Summary This chapter discusses the different aspects of relational databases. Relational databases derive their power from the simplicity of their underlying concepts. Intuitively, a relation may be thought of as a rectangular table, and a relational database management system as the system required maintaining the storage, manipulation ...

A relational database for cardiology

[1990] Proceedings Computers in Cardiology, 2002
The computing needs and design considerations of the Data Retrieval Service (DRS) system are discussed. It is concluded that the DRS system is one solution to the problem of information storage and retrieval for cardiology. By using a 'pseudo-object-oriented', modular approach, the system is flexible, easy to use, and cost effective.
