I would also take a look at MDX which comes from Microsoft for classical analytical processing workloads. I feel that it provides a nice way to think of data in terms of dimensions/attributes and hierarchies and measures as it gives a good way to think of what to aggregate vs what fields to use to do that aggregation. SQL is feels a little more generic and it would be nice for it to have a little more schema aware specifically for analytical workloads.
