Check out these two entertaining websites that teach SQL through interactive games and scenarios. Not only will you have fun playing, but you’ll gain job-ready SQL skills for investigating and making sense of data. SQL Island  SQL Island  provides a visualization game for learning fundamental SQL concepts. You’ve crash-landed on an island and have to query 3 different tables to make your way out.

I think I just found my new favorite SQL practice website. The website is called sql-practice.com  and it is completely free.  This all-in-one website offers SQL training, as well as SQL practice questions. SQL Learning SQL-practice.com has a section called "Learning resources" that includes tutorials for basic SQL queries, filtering, functions (Aggregate, Window, String, etc.), and table manipulation. The tutorials are pretty basic, but work great as a refresher. But if you're just starting out, I still recommend starting with an interactive course like Udacity or SoloLearn .  SQL Practice  SQL-practice.com  is also a great place to practice and test your SQL skills.  It lets you write and run SQL code against two different sample databases. One database has data related to hospital patients and has four tables, and the other one has sample sales data for a fictitious company called Northwind Traders and has eleven tables. You're able to see the schemas for the data

I didn't originally set out to become a data analyst, but it turned out to be a great career decision that led to a rewarding and fruitful career.  In this blog post, I'll share the story of how I became a data analyst, the challenges I encountered along the way, and the valuable lessons I learned. Let's start with my background. I hold a Bachelor's degree in Management Information Systems (MIS), also known as Computer Information Systems (CIS) or IT Management.
