Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Not good at all

This book is impossible to read, and uses way too many buzzwords. Like why can't we call a record a record (Date insists calling it a tuple or relvar)?Knowing these terms is very important, but the direction of computers is toward the average user. And not to those that construct sentences only to sound smarter then others (which many who love Date also love doing).My suggestion: avoid this book as if it were the plague.
