“There is a significant downside - the whole approach works really well when data access is aligned with the aggregates, but what if you want to look at the data in a different way? Order entry naturally stores orders as

aggregates, but analyzing product sales cuts across the aggregate structure. The advantage of not using an aggregate structure in the

database is that it allows you to slice and dice your data different ways for different audiences.

!

This is why aggregate-oriented stores talk so much about map-reduce.”

– Martin Fowler, http://martinfowler.com/bliki/AggregateOrientedDatabase.html
