Figure2 Schematic overview of handling simulated forecasting and simulated historical time series. Three subsequent forecasts are shown, and the resulting complete time series returned when requested after 12:00. The historical time series is traced back using the state used to create the link to a previous run. For the forecast time series the most recent forecast supersedes previous forecasts.

The time series type simulated historical should only be assigned to time series that have a relation to a previous time series through a model state. In all other cases, the time series is independent, and should be allocated simulated forecasting as time series type. |
3.3 Time Series Sets
Any module in DELFT-FEWS that requires data from the database, or produces data that must be stored in the database, does so through the use of a complex data type referred to as the Time Series Set. A time series set can be compared to a query that is run against the database. It contains all the keys to uniquely identify the set of data to be retrieved.
