A lot of tech gurus and course sellers will tell you that you can become a job-ready data scientist in just two weeks or two months. However, they often hide a lot of facts. While it's possible to become a professional data scientist in a short period, this usually assumes you already have a strong foundation in data science fundamentals like statistics, probability, SQL, and Python for data management and analysis, as well as various data wrangling and analysis techniques.
Before you embark on your data science journey, I highly recommend that you take the time to learn these fundamentals. The list of courses I have shared in this blog are from top universities and IBM, offering high-quality education to help you build a solid foundation.
1. Introduction to Databases with SQL – Harvard
Introduction to Databases with SQL is a fantastic starting point for anyone looking to understand the backbone of data storage and manipulation. This course covers the essentials of SQL, the language used to communicate with databases. Through hands-on projects and real-world examples, you will learn how to query databases, design schemas, query optimization, and more.

Conclusion
If you are confused about starting a career in data science or where to begin, I recommend starting with a free data science fundamentals course. These courses are short and cover the basics of Python, SQL, Statistics, and various data analysis techniques. After completing these courses, I highly recommend signing up for a paid bootcamp to become a professional data scientist. The bootcamp will provide you with practical experience and prepare you for the modern workplace.
