It's not, it's a query builder: it helps you write queries without writing actual SQL.

Why DB library is not ORM?

That one I can't answer, but as EllisLab doesn't use an ORM in Expression Engine I suppose they prefer not to use an ORM but write everything specificly in the models.

What is the criteria to be called ORM?

I must admit I'm not entirely sure on the technical definition, but as far as I know an ORM uses objects as representations for data from the database and allows for relations between those objects. A more accurate description can probably be found on Wikipedia.

enlightening answers friend.

but, why CI didn't implement ORM?
i'm , sure with DB library it's can be faster than use ORM.
but, if you didn't use ORM you should take boilerpate code in your app. (especially at association query)..

I have to try to create an ORM library in CI (maybe like DM), but it's only running in MySQL database(it's because technical problem. I couldn't trace name of table from which an attribute come).

if you interested to try you can download it's.

There are existing ORM plugins for CI. DMZ, Doctrine, etc.
