Well, the point of the "data warehouse" systems I have observed has been to come up with ways of doing novel searches for patterns.

This means making the data look like huge matrices that you can do regressions and such on, so that you can hire a bunch of APL programmers to fabricate would-be associations and patterns.

The fact that APL programmers are few and far between, and that the "vice presidents" that are behind DW projects are two generations after those that decided APL was obsolete, means that the projects mostly fail since they don't know the _real_ kinds of skillsets they need.
