If there is one programming language that I would recommend for everyone, it’s Structured Query Language (SQL). SQL (often pronounced “sequel”) is the main language used to communicate with databases including Oracle, SQL Server and Microsoft Access. It’s the set of commands used to write and retrieve data. If you work with any databases in any capacity or want to program for a living, you should learn SQL.
Technically, basic SQL isn’t even “programming” but more of a scripting language. With just a few commands, you can insert, retrieve and update large amounts of information in your database very quickly.
