How to connect to Progress Database

I have read that Progress Database is not supported by Visual Architect.

Does it mean that there is no way to connect to it at runtime via jdbc or does it mean that I can use it but some features are not supported (like reverse engineering for instance) ?

Thank you for your message. We do not allow connecting to a non supported database is because we cannot guarantee the comparability of the datatypes. If you have any further questions, please feel free to contact us again.

Best regards,
