Well I started to create the EOModel and the questions began to arise.
I c that Wonder gives me an id as Pk, but in the model I have te
follwoing, something similar to what David showed in the screencast
(Using the folloing names just to follow the project statement)
Table : Person
Atributes: document
phone
address
so if there is and id as PK, shouldnt I put the document as PK as
well? to avoid data repetitions?
I'm not sure I understand you Gus.
If you have:
Entity: Person Table: Person
id (marked as pk) --> id (defined as primary key)
Then id should uniquely identify a Person in the database. No need to
make a compound primary key.
Is that what you are asking?
