A field is one place where a person can enter or view a particular piece of information. In a form, you might see a field for your name, email address, or delivery instructions.
Think of a field like one labeled box on a paper form. Each box has a job, so the person knows what information belongs there.
Fields can appear in forms, tables, or databases. A clear label should explain what belongs in the field, and the system should say when a required value is missing or not accepted.
