Medical records: I've stored blood type, HIV status, general pathology
results, and radiology results in a database.
A government site I know about stores court records about domestic
violence orders. Access to this information is required on short
notice and its absence can definitely be life threatening.
Life-threatening doesn't have to be realtime.
