Fields
Fields are the individual elements on a form that store data. Fields determine what data a single document can contain. Each field in a document stores a particular kind of data, such as text, numbers, dates or user names. Often users can enter and edit field values, but sometimes data is filled in or changed automatically.
The contents of a filed can be displayed in documents and views or can be retrieved for use in formulas. A field can be defined for a single form or can be defined to be shared among multiple forms in a database.
