SQL and Relational Theory--New from O'Reilly: Write SQL code that does what it's supposed to do

SQL and Relational Theory Sebastopol, CA—SQL is ubiquitous, but it's hard to use. "It's complicated, confusing, and error prone—much more so, I venture to suggest, than its apologists would have you believe," says C.J. Date. "In order to have any hope of writing SQL code that you can be sure is accurate, therefore (meaning it does exactly what it's supposed to do, no more and no less), you must follow some appropriate discipline." The thesis of Date's new book, SQL and Relational Theory (O'Reilly, US $39.99) is that using SQL relationally is the discipline you need. But what does this mean? Isn't SQL relational anyway?

The fact is, understanding SQL's underlying theory is the best way to guarantee that your SQL code is correct and your database schema is robust and maintainable. On the other hand, if you're not well versed in the theory, you can fall into several traps. In SQL and Relational Theory, Date demonstrates how you can apply relational theory directly to your use of SQL. With numerous examples and clear explanations of the reasoning behind them, you'll learn how to deal with common SQL dilemmas, such as:

Database theory and practice have evolved since E. F. Codd originally defined the relational model back in 1969. Independent of any SQL products, SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of the material available anywhere. Anyone with a modest to advanced background in SQL will benefit from the many insights in this book.
