Learn SQL With the New Khan Academy Interactive Course
SQL, a popular programming language used to manipulate data in a relational database, is used in a variety of applications. An introductory SQL course at Khan Academy will help you get started writing SQL in an interactive editor.
The free course will take you from the basics of creating database tables and selecting data to more complex SQL queries and tasks such as joining multiple tables together and modifying databases.
The course can be helpful even if you are not a database administrator. As Khan Academy notes on its blog :
It is not only used by database administrators; These are the engineers who write the code to send data, these are the product managers who make decisions based on it, these are the marketing managers who check if their campaign was successful.
This is a useful skill.
