The use of a database machine for supporting relational databases
ACM SIGARCH Computer Architecture News, 1978One of the goals in the design of database machines of the future is their generality. In addition to being capable of carrying out the common database management functions with high reliability and performance, some of these machines are intended to support more than one data model. A specific database machine, known as the DBC, is intended to support

Bubbles for relational database
ACM SIGARCH Computer Architecture News, 1978The mechanical disk storage is limited by long initial delay, few inputs/outputs, and serial access, thus necessitating large complex programs in existing database systems in order to map the user's view into the physical storage and to provide different access paths in response to different queries.

OrpheusDB: Bolt-on Versioning for Relational Databases
Proceedings of the VLDB Endowment, 2017Data science teams often collaboratively analyze datasets, generating dataset versions at each stage of iterative exploration and analysis. There is a pressing need for a system that can support dataset versioning, enabling such teams to efficiently ...

, 2013 In mathematics a binary relation between two sets \(A\) and \(B\) is a collection of ordered pairs \((a,b)\) belonging to the cartesian product \(A\,\times \,B\). In this chapter we present some of the general properties of relations and their operations, as well some special types of relations defined over the same set.

Physical database design for relational databases
ACM Transactions on Database Systems, 1988This paper describes the concepts used in the implementation of DBDSGN, an experimental physical design tool for relational databases developed at the IBM San Jose Research Laboratory. Given a workload for System R (consisting of a set of SQL statements and their execution frequencies), DBDSGN suggests physical configurations for efficient performance.

Construction of relations in relational databases
ACM Transactions on Database Systems, 1980Using 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

Relational Databases with Ordered Relations
Logic Journal of the IGPL, 2005Summary: The paper deals with expressing preferences in the framework of the relational data model. Preferences have usually a form of a partial ordering. Therefore the question arises how to provide the relational data model with such an ordering.
