I would love to see an analytics database system built on this idea. Let me define my "incoming" tables, and then define how other aggregated or transformed materialized views should be computed, and automatically update the downstream datasets based on changes in the input tables. Let me define only "what" to compute, instead of spending all my time worrying about "how" and "when". Isn't that the point of declarative languages like SQL?
