You mean adding Paradox support to Data Modeler? Unfortunately such database is not supported, and I'm not sure we will ever support it, since it's an old one and very rarely used. Also Paradox has several limitations/differences from the traditional RDBMS that will probably require even more specific code in Data Modeler to be supported.
I would do a manual import of BDE database structure and then generate a similar one in another database supported by Data Modeler (SQLite, MS SQL Server, etc.). Then import that structure in Data Modeler and generate Aurelius code.
Thank you both. I used the demo version of AbsoluteDB migration to port the data and the imported the structure from that DB.
