Database in Depth: Relational Theory for Practitioners
05 Oct '05 - 19:48 by benr
For some reason when I go to LA to visit family I can't stop thinking about databases. The strange thing is that I really hate databases, which any good Frued-ian will tell you means that I'm actually obsessed with 'em. Since I'm in LA, and don't have a laptop, I tend to just troll the net on my brother-in-laws workstation and catch up on things. The last time I did this I found this book: Database in Depth: Relational Theory for Practitioners, while searching O'Reilly's new database books. As soon as I got home I had to buy a copy... and I did.
So for the last month this has become one of my smoking books (ie: a pile of tech books that sit in my garage next to the ashtray which I read in 5 minute snippets while smoking). And, I've got to tell you, this book rules. This type of guide has been needed for years, imho. It dives into the depths of relational theory exploring the "why" of databases and not getting bogged down in the "how". I know how, what I'd like to know is why... most analytical geeks like myself have needed something like this, after getting little snippets of relational theory for years burried in tutorials that were discussing the "how" of the database and only teasing you with the "why". I once went looking to answer some of these questions by trying to get access to some of Codd's writtings, but they are hard to get a hold of and his books are out of print or massively expensive. This book fills all those holes nicely.
I'll be honest, think I'm doppy if you want: I bought this book specifically to answer one question that I've had for a long long time: "What is a tupple?" In most books you don't see the word tupple often, however when you start digging through API's and developing with the database you do. I'd sought out an answer before but only got the mathmatical rendition, which gave me something, but not the answer I was looking for. Much to my delight, when you look in the Table of Contents you find right there in Chapter 3: "What's a Tuple?" Finally!
This book was written by the master of database masters: C.J. Date, who insidently co-created the relational model with E.F. Codd at IBM. If anyone on this planet (sadly Mr. Codd passed away in 2003) knows the relational model that powers the world we live in, its him. You just can't get more definative than this book.
I'll stop pimping the book, you get the idea. Its an excellent read, extremely accessable and yet extremely indepth and complete. He is extremely clear that he's discussing the relational model, not SQL, and even goes on to explain why SQL isn't the ideal tool we often think it is. The book is inexpensive, generally speaking, and the cover art is kickin' to boot.
- Buy the book from Amazon
- An Introduction to Database Systems, Eighth Edition: Another excellent book by Mr. Date
