In database terminology, field is often used to refer to the individual cells within a row or column. However, it can also refer to the whole column itself.
When referring to an individual cell, we’re usually referring to the value within that cell. So a user might ask “what value is in the FirstName field?” when referring to an individual record.
When referring to the whole column, we’re usually referring to the name of the column, its data type, constraints, and any data contained within that column.
