There is a usual DB on Firebird and clients (to it), I want to make it distributed.
How difficult is it? Or is it better to start over?

I have never dealt with distributed databases. Those.:

- создал три БД - в них создал по таблице

now they need to be tied up? And through what? Or how is this done?

And what is distributed in your concept? We created three databases, well, now create something central that will address them and interact between them. And this central will already be accessed by the user.

The essence of a distributed database is that the bases are usually scattered across different computers, and there is a central running process that listens to the client and sends the appropriate commands to the appropriate computer to process information and retrieve the data set. With huge volumes, it makes it possible to calculate data on different computing resources and return only the answer to the client.
