The term field as applied to the database table means:

Vertical column of the table

A database is simply an organised collection of data with ‘tables’ as its fundamental building blocks. Tables allow us to create the framework for storing information in the database. Each column (also called ‘field’) of the table corresponds to a specific characteristic (or ‘attribute’ in database terms) of the stored information. Each row (also called ‘record’) corresponds to a particular instance of the information.
