A predefined row/column format for storing information in a relational database.
a collection of rows or tuples A tuple is a collection of columns or attributes A domain is a pool of values from which the actual attribute values are taken
an unordered set of tuples
a possibly mutable set of tuples of objects
a predicate of two or more places
a predicate with two or more subjects
a set of n- tuples In mathematics, a tuple is a finite sequence of objects (an ordered list of a limited number of objects)
a set of n- tuples that represents the extension of an n-adic predicate
a set of records, called tuples , that represent real-world objects or facts of a given kind, and that conform to a common format
a set of tuples, all with the same heading, none of which have an identical set of name/value associations
a set of tuple s, which are sequences of objects
a subset of a cross product (only some tuples included)
a table that holds the data we are interested in
a table with columns and rows
a table with rows and columns
a two dimensional table made of rows and columns Rows are also called Tuples Columns are also called Attributes Tables are also called Entities More in-depth discussions of these and related concepts are included throughout the rest of this course
In a database, tables are usually linked together in a logical way. A link between two tables is called a \"relation\". A relation always involves two tables ad two columns from them (one can create a relation between a table and itself for representing a tree like structure)
A special type of table in which (a) every row is unique, (b) the columns are in no fixed order and (c) the rows are in no fixed order. All the tables in a relational database will be relations.
(RM) A set of tuples over the same scheme. tables.php
A named, two-dimensional array of rows and columns (i.e., table of data). Each relation consists of a set of named columns and an arbitrary number of unnamed rows. Each cell in the array can have only one value (single-valued) and no two rows may be identical. See also: table, view, RDBMS.
The matematicians' term for special class of table with two distinctive properties: There are no duplicate rows There is no concept of order to the rows Relational Theory
