Hi,

I've just downloaded and read through a few chapters of the documentation and get confused with the idea of 'identifier attribute'

Isn't the identifier attribute similiar the primary-key which we define it ourselves instead of generated by hibernate?

as an example the class User which has following fields:
-username (unique)
-firstname
-lastname

Is the username the identifier attribute? Or shall we create an extra column 'id' just to satisfy the hibernate functionality?

no you can use your natural id as an identifier.

we just recommend surrogate identifiers since they are better in most scenarioes (no matter if you are using hibernate or not)

thansk for the reply.


do you mean, the naturalId is in this case 'username'?


Documentation Feedback
I've been reading the wellwritten reference documentation. But however it takes me more times to get the scattered examples code up and running. Besides this each chapter do not always comes with examples.

And how to start learning through the provided test cases? Is there any brief documentation for each test cases?

tx.
