DATA FIELD
A data field is a place where you can store data. Commonly used to refer to a column in a database or a field in a data entry form or web form. An area in the main memory of the computer in which a data record is contained. A data field is the smallest subdivision of the stored data that can be accessed. A data field can be used to store numerical information such as price, count or a date or time, or even a data and time. A pair of data fields can be used in combination to hold a geo-spatial coordinate. Also, a data field can be used to hold a block of text. A data field takes up permanent storage within the data-store.
