SQL Server is one of the descendants of Ingres, and PostgreSQL is, as the name might suggest, the successor project for database research after Ingres. They're both great databases really, it's a fun connection in their mutual history.

BLI built a relational database machine (IDM), which was influenced by ingres but not much was inherited, code wise. sybase used a VM/pcode architecture, very much not like ingres. https://www.google.com/search?q=britton+lee+inc+wikipedia https://www.google.com/search?q=britton+lee+inc+wikipedia
- jaggederest 4y agoNeat, thanks for elaborating, I knew BLI grew out of the ingres project but not how closely they were related.
