MS Access Avoiding redundancy

[Augustoadipro]

Hey
I would like to know wether access has a feature that can help minimize redundancy by making each record in a table unique rather than assigning a primary key or an index to a field. I mean assigning some sort of index to a record thus preventing one record of a table from looking alike to another record of the same table instead of assigning a primary key to a field.

Use an autonumber. I use autonumbers on every table even the smallest ones.
