How do companies use SQL?
Data is a core part of many web applications and mobile apps. For example, an application like Facebook holds a user’s profile information, including data about their friends and posts. To hold this data, a database system is used. SQL (structured query language) is a programming language that enables programmers to work with that data.

Why should I learn SQL?
Like other programming languages, SQL has its own markup. This makes it necessary for a programmer to learn SQL markup before they can use it effectively.
Besides markup, another feature unique to database programming is the concept of tables. A database may be represented as a number of tables. Each table has its own number of columns and rows and represents a set of data.
