Upload internal DB to AppSheet - Best options

As a newbie to AppSheet I’m wondering what others are doing.

I’ve got an internal Oracle 11g DB that is running our production ERP. I want to access particular tables from the ERP system and deal with data as it’s created and modified through business. For example…

When Orders and OrderDetails are added/modified through the ERP I want to sync that data with AppSheet.

Does anybody else have experience running into this kind of situation?
