Definition
A data structure to organize the tuples of a relation: {<value ix , value iy ,...>, <value jx , value jy ,...>, ...} in a structured way.
An arrangement of numbers, words, symbols or items of any kind, in columns and rows.
One-way table. The values of one or more variables (sets of data) are displayed either horizontally or vertically as a list. Each row or each column represents one data item.
Two-way table. Also known as a contingency table or cross tabulation (cross tab). The rows are labeled with values of one of two variables and the columns with values of the other. The cell at each row and column intersection displays the value of a characteristic of the data that is shared by the two variables when they have the value displayed in the row and column headings.
Multi-way table. The general idea of cross tabulation extended to more than two variables. The rows or columns or both are grouped by values of additional variables.
