Each field is different in a database. A field is a heading for a piece of data. If you were holding data about people the different fields you could have could include: Firstname, Surname, Date of Birth, Phone Number, Gender, Marital Status etc. None of those are the same. You are not going to have two dates of birth for one person or ask them for it twice, so it will be there once, as will all fields. If you are filling in details for a number of people it is possible that some people would have the same details, like obviously lots of people are going to be male. Each of these relates to one person only, and is known as a record. That is different to a field. We can think of fields as being like columns of data and records as being like rows. In a column, all the data will be one thing, like dates of birth. In each row, there will be one entry for each field and all the data relates to one individual.
