KPI Execution
KPIExecution only supports the count distinct
operation that is useful for most (basic) indicators.
- Extend it to allow calculating the
sum
andaverage
.
JPA does not define stddev
which makes min
and max
useless. This requires updating the Observation
entity to add new fields for min, max, stddev (sum and average can be stored as value
).
The type of operation should be an enum.
