Views are virtual tables. That means they should be updatable, just as "real" or base tables are. In fact, view updatability isn't just desirable, it's crucial, for practical reasons as well as theoretical ones. But view updating has always been a controversial topic. Ever since the relational model first appeared, there has been widespread skepticism as to whether (in general) view updating is even possible. In stark contrast to this conventional wisdom, this book shows how views, just like base tables, can always be updated (so long as the updates don't violate any integrity constraints). More generally, it shows how updating always ought to work, regardless of whether the target is a base table or a view. The proposed scheme is 100% consistent with the relational model, but rather different from the way updating works in SQL products today.This book can: Help database products improve in the future Help with a "roll your own" implementation, absent such product improvements Make you aware of the crucial role of predicates and constraints Show you how relational products are really supposed to behave Anyone with a professional interest in the relational model, relational technology, or database systems in general can benefit from this book.

Just as we identify things using information from our senses, so do computers. They can identify physical objects only by using information from their sensors. One of the best-known digital identification techniques is radio frequency identification, or RFID. The RFID tag pasted on the side of a book may seem like a universal marker, but what it means depends on who reads it. Based on the projects from the first edition of Making Things Talk (from the same author), this book shows you how to create projects with Arduino, Processing, and the Getting Started with RFID kit from Maker SHED to identify physical objects.

That's right: JavaScript code is testable, despite the lack of unit test standards for this language. With this book, you'll discover how to devise excellent tests and real-world testing plans for your existing JavaScript code. Developers starting out on a new project will greatly benefit from these guidelines.
