Data is an important part of web applications, mobile apps, and, of course, data science. Data for these applications is stored in a database system. Developers and data scientists need to be able to access that data, manipulate it, extract it, and create it. That’s where SQL comes in!
SQL is operating the databases behind the social networks we use, the apps on our computers, and even our online banking transactions. It’s useful for almost any industry and any application that needs to store or access data.
