In a doctor's database, there would be several fields. The fields could contain the patient's name, address, telephone or mobile number, their Name,Age,Date of birth,Allergies, and the doctor's name. Each thing would have a field of its own. So the patient's name and the doctor's name would be in two separate fields. When the data is viewed, the fields would appear as columns within the data. The fields need to be defined before any data is put in. So you would specify that you want a field for a phone number and a field for a doctor's name etc. when you are designing the database.

Key words:

Field: A field is in a database, it contains important information.
