Parallel algorithm for table division in relational databases

Microprocessing and Microprogramming, 1993
Abstract From a sequential implementation of the division algebraic operator applied to Relational Database tables, we develop and show in this paper a parallel version of the same operator that improve its effectiveness in execution time running on a parallel machine model.

Creating Databases and Tables Inputting Data

1990
In this chapter we show you how to start and finish an SQL session, set up new tables, alter the columns a table contains, type in rows of data, and get rid of a table altogether.

Chapter 15: Managing Large Tables and Databases

2015
Very large tables (where you have row counts in the tens of millions) have special needs. All data manipulations and maintenance operations need special considerations. This chapter will deal with features in SQL Server that can help; specifically, I’ll cover how partitioning a table can ease data movements and how the use of filegroups and data ...

Tables are Not Your Friends: Graph Databases

2015
Proponents of key-value stores, document databases, and relational systems disagree about practically every aspect of database design, but they do agree in one respect: databases are about storing information about “things,” be those things represented by JSON, tables, or binary values.

Creating Database Tables by Running Migrations

2013
We shall need a database to store data for the JRuby on Rails application. Next, create the database table. We shall use migrations to create a database table in Oracle™ database or MySQL™ database. Migrations are Ruby classes used to create and update database tables.

Statistical relational tables for statistical database management

IEEE Transactions on Software Engineering, 1986
E.F. Codd's (1970) relational view is extended to represent statistical data and to achieve its analysis. A new view called a statistical relational table is presented to meet the needs of statisticians, and some of Codd's relational operators are extended to statistical relational tables.

Dynamic generation of database tables for genetic data

Proceedings. 17th IEEE Symposium on Computer-Based Medical Systems, 2004
In this paper, the development of a software tool that will accept an XML file containing genetic data and dynamically generate database tables in which to load the data is reported. Development of the tool is due to two recent developments. First is the increasing number of traditional clinical researchers who want to access to genetic data. Secondly,

Online Random Shuffling of Large Database Tables

IEEE Transactions on Knowledge and Data Engineering, 2007
Many applications require a randomized ordering of input data. Examples include algorithms for online aggregation, data mining, and various randomized algorithms. Most existing work seems to assume that accessing the records from a large database in a randomized order is not a difficult problem.
