KEY column… First app.

Didn’t understand the importance of a KEY column.

While developing my app I changed the KEY column, created new KEY columns, etc.

Now understanding the KEY column is not intended to change, how can I ensure that my many KEY column changes won’t cause problems down the road?

Can I establish a permanent KEY column after the previous changes?

Thanks!
