Each table in a database has an ordered collection of fields, there is always at least one field in a table. The ordered collection behaves like a list, so it is possible to access individual fields by a numbered position (or index) in the list.

A Fields collection can also exist independently of a table, for example when creating an index on a table you will need to define which fields take part in the index. There are many interfaces which either require or return a Fields collection; these include IClass (therefore also IObjectClass and IFeatureClass), ICursor, IIndex, IFeatureClassDraw, IRowBuffer, ISimpleDataConverter, ITableSort and IValidate.
