EMPHATIC uses PostgreSQL databases (standard for Fermilab experiments) via two Fermilab-supported web interfaces:
- Query Engine — general query interface for flat tables (simple rows and columns)
- Conditions Database — for conditions tables, where data is associated with a validity context (at minimum: timestamp and channel)
EMPHATIC also uses the IFBeam database, which stores beamline settings and
readbacks. The SpillInfo package handles all IFBeam queries and populates the
rb::Spill data product.
