The introduction on real data systems - The free one enhanced my overall view of data infrastructure

Giving out real world examples and problem solving. Good depection of concepts through labs and a helping community
By Khan
What I liked most is that you actually do the work, not just watch videos. Zach made us personal accounts in Databricks so we practice on the same tools companies use every day. That was huge for me because it feels like you are working at a real job, not doing some tutorial. The homework is where I learned the most. The Spark one gave us a broken pipeline and we had to fix it. It was hard but that is how you actually learn. You go through the code line by line, understand what it does, and then you start seeing ways to make it better. That does not happen if you just let AI write everything and never read it. Zach makes you do the work and explain what is going on. I like that. The more you practice the more things click. Good bootcamp, would recommend.
