This is a mock-up book for test purpose: only the first two chapters have been written.We put this mock-up online to launch a "near real condition" test, to assess whether this is a book worth writing.
After going through Real-life SQL, you will be able to use SQL to analyze and fix the business issues that you face. If SQL was English, after two weeks with this book you would be able to order a pizza and in four weeks' time you would be fluent.
This book has an absolute focus on practice, keeping theory at minimum. We start from a 'real-life' business questions and provide the SQL needed to answer it. It indeed used to be the job of IT people to "speak" SQL to retrieve data. Managers needed only to be able to analyze data with Excel. Things are changing fast. For many companies, "speaking" SQL has become a key competency, like Excel was 15 years ago.
If you invest 30 minutes of your time per work day, it will take you four weeks to go through the book.
