The Best Way To Learn SQL: an Easy Way to Learn

SQL, or Structured Query Language, isn’t like most other programming languages. Instead of being flexible and versatile with several use cases — like Python or Java for example — SQL has very clear-cut uses. SQL is used solely for accessing and manipulating databases. This means that if you want to become some sort of database administrator or data analysis expert, you need to figure out the best way to learn SQL.

Don’t worry though, you’re not alone. Data collection and analysis is becoming more and more common, and most media to large businesses have databases in some form or another. The data in these databases is analyzed to inform marketing and business strategy decisions, which has led to a huge demand for experienced SQL programmers.

Some of the best-recommended ways to learn are taking SQL-based courses on platforms like DataCamp. However, today, I’ll introduce you to more strategies that you can add to your studying plan.

So how can you become an expert in SQL?

Which Online Courses Should You Choose?

When you break down the pros and cons of the various methods of teaching programming, online courses come out on top by a huge margin. Programming with any language — including SQL — is done with a computer, so it makes sense to learn how to use SQL via an online course, instead of using textbooks or offline learning techniques.

A few of the other benefits of learning online, proving, that it’s one of the best ways to learn SQL and more, include:

  • Online courses are usually clear and concise. This means that you won’t be wasting time trying to learn things that you don’t need to. Instead, you will get straight to the point, learning the concepts and information that you need. This will save you time and will help you learn SQL much faster and more efficiently.
  • They offer flexibility. The structure of most online courses means that they are perfect for a flexible learner. Instead of having to attend scheduled classes and learn according to a strict course outline, you will be able to learn when you want, for as long as you want, as often as you want. This flexibility is great for people with disabilities, for people with children, or for people who have to work full time and therefore can’t attend physical courses.
  • They let you learn at your own pace. This is great for people who haven’t tried to learn a new skill for a long time. Being able to learn at your own pace means that you should be able to learn all the skills you need to become a SQL superstar, even if it takes you longer than the average person.
  • They are usually very affordable. Online courses are the best way to learn SQL free. Even if you can’t find free SQL training that you like, there are plenty of online courses out there that only cost a few dollars to enroll in. And if you don’t have even those few dollars, there are also scholarships to get course fees funded to apply for.

While it can sometimes seem difficult to navigate your steps and transition from the beginner level to a more difficult one, some platforms offer series of courses that each you everything in order of development. Take the SQL Fundamentals skill track on DataCamp for example – it starts at complete basics and starts introducing more intermediate concepts as you learn.

How Do I Choose An Online Course?

When you’re choosing an online course — for anything — you need to look closely at the reputation of the person or business who is providing the course. Try and find courses that are created by people with a strong reputation. This will increase your chances of choosing a high-quality course. To make your decision easier, feel free to examine our list of the best MOOC providers, which includes names like DataCamp and Udacity.

Past Reviews

Another essential factor when it comes to choosing the right online SQL course is the experiences of past students. Past reviews are a major factor that you should base your choice on. Try and find a course with at least 90% positive ratings, and make sure you pay attention to written reviews as well.

Consider the Course’s Content

You should also pay close attention to what the course claims to teach and make sure that it fits what you want to learn. For example, the Interactive SQL Tutorial will teach you the basics of SQL coding, databases, and other important concepts without going into too much detail.
