What to choose in PHP for working with multiple ORM databases (allocation of common data to a separate database)?

Question

PHP

I have a database of products for 15 sites.
I want to make one common database, and in the databases for stores, make only the properties open or hidden and go to the corresponding general data.
The difference on the sites is only hidden and open, why duplicate it.
But then the question arises Doctrine, as I understand it, works with one base.
And I need to either write in SQL, join from different databases.
Or, is that right?
Queues are kind of for queuing requests for controllers, not for getting related data.
A number of tables are large and not willing to store with duplicates.

Answer 1

Doctrine can work with multiple databases.
