identify a primary (key) attribute (field) for each entity, and then produce a diagram of the final logical model (include remaining functional dependencies, and referential integrity constraints)
If there are not enough natural primary (key) fields for all your entities ( tables) introduce the convenient fields synthesized just for those tables that you need a key field and do not have a natural field (e.g. item id for a table in an inventory database where no key field exists).
Create the diagram of your normalized model with a final listing of attributes with key attributes identified.
