Introduces some basic relational database terminology.

Tables

A database table is just that, a table with rows and columns. Different tables contain information about different types of things.

Rows

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.

Columns

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.

Example

The Instructors table.
