# Aggregations

MDA (through the TisGraph adapter) supports several aggregating functions.


In future versions, we would like to add aggregating time series as a native concept in MDA.

# Weighted Average

The currently implemented "weighted average" as shown in value search, time based protocols, and in TISGraph regards any value as "constant until the next value". This helps a lot in calculating the boundary weight values of the aggregation (like start/end of the day).
