Good beginners books on databases? [closed]

I am looking for recommendations on database books. Ideally, I would like a book spending no more than 1/4 covering the basics of the abstract / theoretical stuff, and then delves into the practical aspects.

If the relevant "Dummies book" is good, this would be fine, as long as people here would endorse it. Brownie points for books available on Kindle.

Solution 1:

My two favorite have been Database Design for Mere Mortals and SQL Queries for Mere Mortals by Michael J Hernandez which Amazon does have available for the Kindle.

Solution 2:

I found the "SQL Server for Dummies" book to be pretty good. It's the only "Dummies" book I've ever read, but a friend recommended it when I asked about a good intro to RDBMSs.
