My name is Uzomah Teslim. Learning SQL as a data scientist can be incredibly boring. I ended up stuck in tutorial hell because the content out there, while good, teaches data professionals things they do not always need. I am not a data engineer. I am a data scientist. I just want to query data, understand what it is saying, and export it to a Jupyter Notebook where I can use Python for further analysis.
I love visual data. The best way for me to analyze data is through Python using libraries like NumPy, Pandas, and Matplotlib. Because of this, learning SQL felt so tedious that I kept procrastinating. I only finally sat down to learn it when I was actively looking for a job.That experience is exactly why I decided to write this book. I want to give people an easy, practical way to learn SQL. In this book, you will set up an SQL environment, import data, and start analyzing it from the very first day. You will actually understand why you are writing specific queries instead of just learning commands for the sake of memorization.We are also in the era of AI. You should know that for data analysis, AI tools like Gemini and Claude can write SQL better and faster than most humans. The only thing you truly need is to understand the core concepts of SQL and how to structure a query. Once you have that foundation, you can use AI to become incredibly efficient.This book is for absolute beginners. There are no advanced topics here, meaning anyone can pick this up and learn. After reading this book and practicing, you will feel very confident. You will have the exact foundation you need to learn advanced topics on your own later.However, I have one major request. Even though I just praised AI and believe you should embrace it, I am begging you not to use AI while working through this book. Please type every line of code yourself. Make mistakes and see the errors. That is how you truly learn.This is the first book I have ever written. If you like it, please send me a message. If you do not like it, I still want you to send me a message.Read More
