How about the "Derived Fields" feature of Qlik Sense 1.1 and memory

[petter]

The new Derived Fields feature that was introduced in Qlik Sense 1.1 allows you to associate derived fields from for instance a date.

I suppose this feature is implemented efficiently as a calculated thing or will these derived fields end up as stored values in "hidden" fields in the data model.

I would welcome some clarification from someone with the technical knowledge on how it is implemented

Due to my impatience I had to investigate myself - it was really a quick job to determine if a huge number of dates in three date fields would inflate into a larger application size when applying Derived Fields on all three of the date fields.

Well it didn't - that is very good news indeed - it makes Sense !

So the implications are that with this mechanism we could have much "better" data models - meaning slimmer and faster and less cluttered than before. For some applications this is a huge benefit.
