Hi,
I have just started entity modelling (oracle/sql plus) and I have got a bit stuck.
How do you know what your primary tables are?
Is it something that you are able to identify with experience or is there a way of spotting them, i.e looking for characteristics about the tables, criteria etc?
I think I have found a logical progression for the model but I wanted to know if there is an exact way to identify primaries to back up my ideas.
Cheers!
