Data changes over time. In this course, you will learn how to keep data records current using SQL’s INSERT, DELETE, and UPDATE commands. These three operations represent the basics of DML (Data Manipulation Language, a special set of SQL commands). They give you the power to control the information inside your database.

If you use a relational database, you’ve probably heard about CRUD. That’s an acronym for the most important part of DML operations. This course will explain the meaning of CRUD and help you become a more proficient database user.

You may already know how to retrieve information from a database using SELECT statements. Find out how to take your SQL skills to the next level with this course!
