We have included both free and paid courses, that are suitable for all levels, to ensure that you can find a course best suited to you!

But first, let’s answer a very important question – what is SQL? 

 Structured Query Language (or SQL) is a domain-specific language used in programming and design for managing data held in a relational database management system, or for stream processing in a relational data stream management system (RDSMS). 

SQL offers two main advantages over older read-write APIs, such as ISAM or VSAM. Firstly, it introduced the concept of accessing many records with one single command. Secondly, it eliminates the need to specify how to reach a record. 

If you are working in an IT, programming or cybersecurity role, or are someone who would one-day like to work in one of these roles, you can learn how to code using SQL through online learning. Suitable for all levels, I have spent the time researching the best online SQL tutorials out there.
