Choosing a database schema generator?

Question

Database design

Hello.
The task is to draw a database schema (more than 300 tables) and generate a sql script for different DBMS (oracle, ms sql, mysql etc.).
Preferably free and desktop. Found a list of programs https://wiki.postgresql.org/wiki/Main_Page
Who can advise what from them?
