My Ph.D. advisor gave me his copy when I was just getting started with my thesis, almost twenty years ago. I remember spending 6-7 very intense weeks with it. It gave me most of the mathematical/logical background specific to databases I needed to finish what was primarily a DB focused dissertation. I kept coming back to it all through my studies and later. If you ever need to design a logically sound query processor/optimizer and/or data storage layer, this is a book you should study. It still sits on my bookshelf, waiting for the student whose interest in databases is deeper than dujourDB, so that I can pass it down to them.
