Relational Theory Course Plus Book Collection

There’s a great deal more to relational theory than most people realize. Of course, the relational model, which that theory is built on, is essentially quite simple—you can learn it pretty well in an hour or two, maybe less—but it has amazing depths, and implications that are yet to be fully explored. This one of a kind seminar examines some of those depths and implications. To set the scene, it opens with a preliminary overview of what the relational model and relational DBMSs are really all about—and even that overview might provide a few surprises, if your knowledge of such matters derives only from SQL. It then goes on to build on that foundation, taking closer looks at a series of important topics, including type theory, updating, language design, constraints, database design, views and view updating, temporal data, and missing information.

Top 5 reasons to take this course:

  1. Learn relational theory directly from the legend.
  2. Self-paced video training, so go at your own speed. You will have access to the course for one year starting from the date of purchase.
  3. 70+ topics spanning 10+ hours. Each topic is short (5-15 minute) to maximize learning and retention.
  4. Receive interactive access to all eight books for one year.
  5. Download PDF copies of all eight books for your future reference.

About C.J. Date's Books

Keys, Foreign Keys, and Relational Theory

Keys and foreign keys play a crucial role in relational databases—keys identify the objects of interest, and foreign keys knit those objects together. The basic idea couldn’t be simpler. As so often, however, the devil is in the detail … The fact is, these concepts aren’t quite as straightforward as they might seem on first acquaintance—or, at least, such would appear to be the case, if the literature is anything to go by. In this one of a kind book, noted database author C. J. Date traces the somewhat checkered history of the key and foreign key concepts, shedding some light on what turns out to be, on occasion, a surprisingly murky subject and explaining in detail what proper support should look like in true relational products.

On Cantor and the Transfinite

The aim of this book is to explain and investigate the claims of Cantor’s in depth (and question them, where appropriate). It’s not a textbook, though; instead, it’s a popular account—it tells a story—and the target audience is interested lay readers, not mathematicians or logicians.
