Structured query language, or SQL, is a programming language, but it’s not just for programmers. In fact, it’s probably the language you should learn even if coding seemingly has nothing to do with your career.

SQL is used to communicate with databases. As data increasingly informs nearly every industry under the sun, SQL is widely used for database management and to pull, edit, manipulate, and add information to databases.

Think of it as a language for asking questions. Writing SQL is writing a code that will ask databases to group information based on what you or your company is looking to learn.

Even if you’re in a field that doesn’t normally require coding know-how, SQL can make you better at your job. It can make data analysis easier for anyone who works with data: marketers, those in business, and data scientists can all use SQL to inform their work. Thinking critically about data enables you to provide informed insights and to make better decisions for your company.

Cloud Computing: How much time will it take to learn SQL?

Online courses are a great way to learn SQL and database management — just don’t expect it to be something you can learn in a day. Most experts say that investing at least a few weeks into your training is ideal. That’s why online courses are so great. You’ll be learning at your own pace, which is always nice when learning something new. Many online SQL courses are downloadable, so you’ll be able to go back and repeat tutorials if you’re feeling lost or if you need a refresher at any point in your career. 

As with any coding class, the best way to learn SQL is by doing. An interactive online class with lots of hands-on exercises will help you to learn how to form queries and get your SQL skills in tip-top shape.

It’s also important to pay attention to optimization when using SQL. As you learn more advanced SQL, efficiency will be key when writing queries. There are classes dedicated to SQL optimization for those already acquainted with the fundamentals.
