false 2647376 1 The newest edition of the classic <I>An Introduction to Database Systems</I> incorporates the latest developments in relational databases, including semantic modeling, decision support, and temporal modeling. There's better information on distributed databases, security, and the mathematics of relational databases too. With the same strong coverage of fundamental theory that made its predecessors stand out, this book ranks as the definitive textbook for those studying database systems.<p> This is an extraordinarily academic book. In his preface, C.J. Date goes so far as to lament having to use Structured Query Language (SQL) in some of his examples because it's "so far from being a true embodiment of relational principles." What's more, he writes in a very academic style, peppering his heavily footnoted prose with mathematical expressions and words like relevar and tuple. The academic style and highbrow language isn't a bad thing, since this book deals with complicated, largely abstract phenomena in depth. <p> Be aware that <I>An Introduction to Database Systems</I> is a far cry from the highly graphical, problem-focused books that target the community of commercial database developers, and as such requires more careful study. This book is about theories, concepts, and ideals rather than problems, solutions, and specific implementations. Per se, it will enable you to become a better database programmer--but only if you supplement it with practical guides and hands-on experience. <I>--David Wall</I> 2672116 10 1999 An Introduction to Database Systems total:2|3:2| 2 6 7 0 0 0 false false Wed Oct 21 10:16:54 -0700 2009 Wed Oct 21 10:16:54 -0700 2009 0 0 false false Sat Jan 24 23:42:07 -0800 2009 Sat Jan 24 23:42:07 -0800 2009 0 0 false false Sat Aug 16 04:04:29 -0700 2008 Sat Aug 16 04:04:33 -0700 2008 3 0 false false Sun Apr 20 19:34:59 -0700 2008 Wed Apr 30 03:04:02 -0700 2008 0 0 false false Sun Apr 13 09:11:17 -0700 2008 Sat Jun 07 20:23:15 -0700 2008 0 0 false false Wed Jan 30 15:04:34 -0800 2008 Wed Jan 30 15:04:34 -0800 2008 3 0 false false Sat Jan 26 23:56:09 -0800 2008 Sat Jan 26 23:56:09 -0800 2008 http://www.goodreads.com/book_link/follow/8?book_id=2647376
