What does the term field mean in relation to databases?

Answer 1

The field is where data is entered. For example, a phone book database may have fields such as LName, FName, Add1, Add2, City, ST, ZIP, AC, Phone. Also, for the phone company's version of said database, they may have some additional fields such as Unlisted, NoAddr (as not everyone wants their addresses in the phone book), FInit (since some want only their first initials rather than their names in the phone book), etc. Fields can be of various types, of course, such as numeric, string/text, boolean, time/date, and more. What data types are allowed depend on what type of database software you are using or whether you are custom designing your own software by programming in C, Pascal, or another such language.
