I agree that it is a great textbook. Another good text with a formal treatment of relational theory is Foundation of Databases, also free for personal use:

On a side note, Elmasri and Navathe's book, despite being one of the standard textbooks in many academic courses, is not among my favorite. Some chapters are pretty good (e.g., the treatment of indexes), but others are less satisfactory (e.g., the parts on normalization and security come to my mind). If I recall correctly, though, the part on relational languages was quite ok.
