Hi Denis.

>I guess that multi-companies would be done within the application. That is the user wants to create a new company then I create a copy of the database to another DB and in the future when the app is launched I ask which company needs to use the app. That's why I'm wondering if SDT could still manage this multi-companies thing.

Yes, SDT can help with this. See the second question ("How can SDT help me work with multiple datasets?") in the Frequently Asked Questions topic in the help file.
