The control system tools tend to deal with the IOC database via channel access or PV access.
When an operator pushes a button in the middle of the night, we expect that to work right away and not take time while it's connecting to some relational database, maybe fail.

Mind you it's perfectly normal that for example the location of devices and related details is held in some site-specific relational database, and then tools like python are used to create EPICS databases for the IOC records, display files for operator interfaces etc.
But that's done comparably infrequently. Say on a maintenance day, control system engineers might trigger the 'build' of IOC and display configs, restart IOCs etc.
From then on, the IOCs just run and the displays which were generated with info from a relational database are simply files on the disk, they're not re-generated whenever a user pushes a button.
