Exporting a Database schema and triggers

I have a small problem at work. Our DBA went on a journey of self-discovery ... I am very happy for him and I hope he finds what he is looking for. But he left us without any information about how the database he created works, the triggers he has, the connections between tables and, frankly, no documentation. My question is whether it is possible to export all the information from the database (connections between tables, schema, triggers, fields with data type, etc .. :) in a file from TOAD or another application to mount it in some application that would reverse engineer the database to indicate that same information that we need. I thank you very much for the help you can give me!
