Over the years I have seen a move to a more temporal view of AGGREGATES. As an advocate of functional programming, I prefer this approach, but I think seeing this as an “X is better than Y” proposition is naive. Rather, having these as tools in the toolbox is a far more pragmatic approach when it comes to designing, developing, and maintaining software systems.
Explore some of the flavours that an AGGREGATE could take and walk through some of the reasons why you may want to pick a specific flavour.
