I am planning to create a website in odoo, but I want 3 different wesbites but their inventory should be centralized, but all of the three should have different domain names like abc.com, xyz.co or xyz.cuk or something like this nut the inventory , product creation can be done from one place only.

Is this thing possible in odoo online version?

If yes then how? in Odoo Online version only first and if not possibe in online version then in  sh?
