Answer 3

SQL is not a programming language! SQL stands for "Structured Query Language". It is designed to query and output data from relational databases and you can join, mix and transform the data from tables and views in virtually any way. It's extremely powerful for data transformation and the de facto standard as a database query language. But on the other hand it is not designed to do programming. For example there is no way to do loops with SQL. Oracle has developed PL/SQL to implement programming concepts on top.

So, it is a very important complement to any other programming language if you ever work with databases and the Web does involve a ton of them in the backend!

You most probably get in touch with it if you learn PHP since it usually processes the backend of Webpages and frequently data from a database is involved. Now, PHP itself can't query the databases. SQL is required for this purpose.
