A relation is considered a:
A. Column.
B. one-dimensional table.
C. two-dimensional table.
D. three-dimensional table.
Answer: Option C
Solution (By Examveda Team)
- A column in a relation represents a single attribute or field in a table.- A one-dimensional table is not a valid concept in the relational model. Tables in the relational model are typically two-dimensional, with rows and columns.
- A two-dimensional table is the correct representation of a relation in the relational model. It consists of rows and columns to store data in a structured format.
- A three-dimensional table is not a valid concept in the relational model. Relations are typically represented as two-dimensional tables.
Therefore, a relation is considered a two-dimensional table.
