OLAP Resources

If anybody knows of OLAP products which are represented on the Web somewhere, please let me know, and I'll put in a link from the product page.

This page is less product specific and is one of several pages around the Web that focus on OLAP. So far, I've got the following links to other resources. I invite more. Thanks to all the contributors.
N.B. Just because I put in a link does not mean I agree with what they say.
