The Art of SQL
My dad and I went for a wander in the Harvard "Coop" bookshop this afternoon — after Paul's tour — and while there, I couldn't resist buying just one more geeky book. The Art of SQL is a very impressive text, that explains practical problems to some of the most common problems related to SQL querying, SQL data manipulation, and database design. The section on dealing with hierarchical data in a relational environment looks particularly interesting. And as with the drupal book that I bought a few days ago, this one also earned a much-coveted Slashdot review.
