Description
Along with its companion volume (Database Dreaming Volume I), this book offers a collection of essays on the general topic of relational databases and relational database technology. Most of those essays, though not all, have been published before, but only in journals and magazines that are now hard to find or in books that are now out of print. Here's a lightly edited excerpt from the preface (so this is the author speaking):
I went back and reviewed all of those early essays, looking for ones that seemed worth reviving (or, rather, revising and reviving) at this time. Of course, some of them definitely weren't! However, out of a total of around 130 original papers, I did find some 20 or so that seemed to me worth preserving and hadn't already been incorporated in, or superseded by, more recent books of mine. So I tracked down the original versions of those 20 or so papers and set to work. When I was done, though, I found I had somewhere in excess of 600 pages on my hands-too much, in my view, for just one book, and so I split them across two separate volumes.
Highlights of the present volume include a detailed explanation of the multiple assignment operator and why it's so essential; an investigation into why object and database technologies are so much more different than they're often made out to be; a critical examination of SQL's support for pointers ("references"); a tutorial on the counterintuitive (but crucial) concept of tables with no columns; and an annotated and extended debate between the author and E. F. Codd, inventor of the relational model, on the subject of nulls and three-valued logic.
