The book concisely presents all the necessary topics related to databases and SQL techniques that are important for any data scientist or data engineer to know.

Everything has been presented clearly with examples and screenshots for better understanding.
This is not a book you read. It is a book that you thumb through and get familiar with the material in it. You can pick up a few tips and answers to problems that might keep you from continuing a project. Nice book. Simplistic.
