Thought to give back to some Knack/database newbies, share some of the things I've learned.
I see myself having a need for the following fields for most objects:
1) Date Created
2) Date Updated
3) Created by (user)
4) Updated by (user)
5) ID # (auto increment field)
^I find it is always better to include these fields when you first create an object, and delete them at a later date if there is no need for them, rather then to build it in after the fact.
I also think that building those core fields into each object will make your life easier going forward.
Maybe these things are covered in "Database 101" ... ???
*It is also a good idea to foresee all the possible User Types and create them at the very beginning also...
