Introduction
5. SQL

Instruction

So, how do we get in touch with our database? We use the so-called Structured Query Language. Of course, no one uses the full name, we just call it SQL for short.

All relational databases understand SQL, but each of them has a slightly different dialect, so to speak.

In this course, you will learn the basics of the standard SQL which will be understood by every relational database. Thanks to SQL, you'll be able to make queries in each database environment.
