Publisher's Synopsis
There's a lot of buzz in the tech world about data-but of course, raw data isn't very useful on its own. That's where a language called SQL (also called Sequel) comes in.
What Is SQL?
Data is a core part of many web applications and mobile apps. For example, an application like Facebook holds a user's profile information, including data about their friends and posts. To hold this data, a database system is used. SQL is a programming language that enables programmers to work with that data.
Having advanced knowledge of SQL broadens your horizon in using Oracle and a host of other programming languages. With this book, you will have everything you need to succeed and become that geek you have always envisioned by learning how to put the power and flexibility of this language to work.
