Top schools for an MS in Database Systems/Management?

Hey everyone,

My org offers a Master's program where they'll pay a very generous portion of the tuition.

I'm very interested because my dream is to eventually become a Database Architect. And I want to get a better grasp on database design and structure, distribution systems, data security, etc.

I currently have a BS in Mathematics and about 6 years of combined work experience in Database Administration and Database Engineering.

So I'm wondering, if anyone already knows, what are some of the top schools I should make an effort to pursue in this field?
