I don't know if you mean to create multiple Fmp12 filemaker database files. Because that would be a really bad idea in my opinion.
But it is perfectly possible to make one fmp12 Filemaker file with different sections (Tables) and create a Menu (Table Of Contents) that allows you to go to the different layouts that make up the database.
This kind of menu can be seen in action in this video:
This is a promo video for a Udemy course that will be coming online any day now.

You can watch that for free.
Sorry no i meant tables, not actual databases.
Thank you for the video, definitely helped with this problem.
