SQL is the most in-demand skill to learn. No surprise that SQL developers are earning the highest salaries in the IT industry. Want to learn why we need SQL statements in every single programming language? This SQL developer tutorial on SQL basics will fill you in to the subject and get you on track with the most-needed tool.
In the most simple way, SQL is the language that allows you to interact with the database. One day, you might encounter a chance when you run out of Excel lines (which happens when you reach 1 million in a sheet). Or you may face an enormous variety of related data that it’s unbearable to manage. For example, in cases when you need to analyze customer behaviors. For that, you’d need to check their transactions, then any support inquiries they made, customer’s contact details – everything in one place. (And if you have big numbers of customers, you’ll eventually run in a dead-end reaching the 1M Excel lines.)
To handle this much of data, you’ll need a computer language that will put it into a database and provide you with the ability to extract the data out. The only way to give information back to your users according to their requests is by SQL statements. And for that, you need the SQL. As we know, the digital age is marked by the growing amount of Big Data, so you better learn SQL basics and jump into the train at the right time.
This course is organized into a clear roadmap so that you have the best way to learn SQL. After the introductory part which you can peek into for free, you’ll follow 5 sections to get a hold of the SQL basics.
This SQL course is suitable for complete beginners, and I strongly recommend it to university and college students if you want to learn writing SQL queries quickly. And of course, those who will finish this SQL developer tutorial will walk away with SQL certifications for beginners.
The best way to learn SQL is by combining the theory with realistic examples. From my personal experience (working as a freelance developer and web designer from 2011), I’ve got an extensive portfolio of these. So, learn to build a robust SQL query and many more fundamentals for your career. I’ll see you inside the SQL developer tutorial!
