NoSQL Databases and Data Warehousing

I didn’t know data warehousing strictly imposes a relational model:

From a philosophical standpoint, my largest problem with NoSQL databases is that they don’t respect relational theory. In short, they aren’t meant to deal with sets of data, but lists. Relational algebra was created to deal with the large sets of data and have them interact. Reporting and analytics rely on that.

I’d bet people building and using Hive, Pig, Flume and other data warehousing tools would disagree with Eric Hewitt.
