Hello
I whant to build an main site + two sub domains like in atached pictures.
If possible I'd like to each main and two secondary domains have their own database.
It is necessary that the main and two sub-domains, users have single login.
If this option is not possible, I only use two databases, one for the main, one for the two side domains, but with the same shared login.
I want to use multiple databases to allocate one server for each, in the event of high traffic.
Which of the two variants are possible?
