Parallelism in relational database management systems
IBM Systems Journal, 1994In order to provide real-time responses to complex queries involving large volumes of data, it has become necessary to exploit parallelism in query processing. This paper addresses the issues and solutions relating to intraquery parallelism in a relational database management system (DBMS).

Access path selection in a relational database management system
Proceedings of the 1979 ACM SIGMOD international conference on Management of data - SIGMOD '79, 1979In a high level query and data manipulation language such as SQL, requests are stated non-procedurally, without reference to access paths. This paper describes how System R chooses access paths for both simple (single relation) and complex queries (such as joins), given a user specification of desired data as a boolean expression of predicates.

Comparative analysis of the selected relational database management systems
2017 40th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2017The database management system is a software that enables easier work with databases i.e. to define database structure, retrieve stored data, enter data into the database and process the previously stored data in the database. In this article we have compared 3 relational database management systems (RDBMS) - Oracle 11g, MySQL and PostgreSQL.

Buffer management algorithms for relational database management systems
Information and Software Technology, 1988Abstract Buffer management is an essential component of database management systems (DBMSs). This paper reviews and classifies various buffering algorithms for relational DBMSs. A new classification criterion is proposed. It is based on a judgment of how the knowledge of query reference behaviour is reflected in buffering policies.

Relational database management systems and industrial engineering
Computers & Industrial Engineering, 1992Abstract Traditionally, industrial engineers (IE's) have been involved with the synthesis of people materials, equipment, and energy into improved workable systems. As these systems have expanded to include information, so has the scope of industrial engineering.

Understanding Relational Database Management Systems
2003Call me Ishmael. We are about to learn about the White Whale: the Relational Database Management System (RDBMS). RDBMS is the most common type of data storage in business today, because it is a proven and well-supported technology. In this chapter, I will discuss what a relational database is and how you can use one. I will try to touch on most aspects
