Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I've been quite happy with this book. I've been learning SQL basically through experimentation and Google Searches. This book does a very nice job of guiding the user along. It is very easy to follow. The book will serve as a handy reference I'm sure.
This is my favorite book on SQL Server. It is easy to find what you need if you forget syntax and just need a reminder. I doubt if you could really teach your self T-SQL from the book, especially in 10 minutes, but it is the best sourse I have found when used as a reference book.
