Hey there

Thank you for posting in the Lucid Community! Lucidchart does not formally support Real Database as a datasource however you can create a custom query. If you are able to generate an output file in the format our ERD importer expects you should be able to import successfully. If you need some guidance on how this file format would need to look please reach out to us directly at support@lucidchart.com we would be happy to help!

Please let me know if you have any other questions or concerns! Cheers
