Hello
For the statistic-stuff I propose the following enhancements/changements:
1) remove meanDelayArrival, meanDelayDeparture and meanDelayStopTime from
the entryType
in the statistic entity:
2) change the source to a dataReference-object containing dataSource,
dataDateTime and dataStatus
3) add a text field (dataDescription) to describe data like: "Testdata
March 2005" and so on
4) meanArrival, meanDeparture, medianArrival, medianDeparture as timestamps
5) meanArrivalDay, meanDepartureDay, medianArrivalDay, medianDepartureDay
as date
6) meanArrivalDelay, meanDepartureDelay, medianArrivalDelay,
medianDepartureDelay as number
value
7) standardDeviationArrival, standardDeviationDeparture as numberValue
8) a list containing per element:
- percentage, maxDelayArrival, meanDelayArrival, medianDelayArrival,
maxDelayDeparture,
meanDelayDeparture, medianDelayDeparture
This would be useful to store data like e.g. 75% of the trains have less
delay than 1.7 minutes etc.
Best Regards
Markus
