Data is one of the most critical assets of any business. Data needs a database to store and process data quickly. SQL is a language used for a database to query data.

In this introductory course, you’ll learn the basics of the SQL language and the relational databases. You’ll start by learning about the relational model and relational model concepts and constraints. By the end of this course, you will have learned and used the five basic SQL statements, some advanced SQL syntax, and join statements.

This isn’t your typical textbook introduction. You’re not just learning through lectures. At the end of each module there are assignments, hands-on exercises, review questions, and also a final exam. Successfully completing this course earns you a certificate. So let’s get started!
