SQL language is an interface between the programmer and the database, it is your database communication assistant. With SQL, a database is born, and this database becomes your child that you grow with care, paying attention to all the data that comes in and out because you control this. With SQL language of course. How many times in your real life have you been worried because a dear person was ill or needed extra attention? Well, a database needs to be treated similarly. You have to always ask her how she feels, what she's done in the last 24 hours, if anything hurts. And these are not just polite questions. You really need to check this out, of course if you want your own day of work to be an easy one, because it's not too much worry. You probably realize that your daily database dialogue is once again accomplished through SQL. But what kind of language is that? How can I know to know him, to master him? Before you answer, think how your parents taught you to eat, drink water, be on your feet. This book, which I am glad to read, I hope to play your parents' role. It will take your steps (better say the thoughts) to all the answers you need. I trust you will do what you have in mind. Success!
