What is a row?

Each row in a database table represents one instance of the type of object described in that table. A row is also called a record .

What is a column?

The columns in a table are the set of facts that we keep track of about that type of object. A column is also called an attribute or field. Also referred to as a labeled element of a tuple (a tuple lets us “chunk” together related information and use it as a single thing).

What is a table?

A database table is just that, a table with rows and columns. Different tables contain information about different types of things (a set of tuples sharing the same attributes; a set of columns and rows). Also reffered to as Relation or Base relvar.

  1. What is a row?
