Requirements
Basic Computing Skills: Students should be comfortable with using a computer, installing software, and navigating the internet.
Familiarity with Programming: While not absolutely necessary, some familiarity with programming concepts would be advantageous. This could be in any language, not necessarily Python or SQL.
Understanding of Databases: Basic understanding of what a database is and why it is used can be helpful. Familiarity with SQL would be a bonus but is not required.
Python Installation: It's recommended to have a recent version of Python (3.x) installed on your system. You should also install Jupyter Notebook, which is a popular tool for running Python code. The installations are covered in the course.
PostgreSQL Installation: You'll need to install PostgreSQL on your system. Don't worry if you're not sure how to do this, as the course will guide you through the process.
Willingness to Learn: Most importantly, you should be curious and willing to learn new concepts and tools. This is a hands-on course, so you'll need to be ready to get involved and experiment with the code and concepts.
While meeting all these prerequisites will help you get the most out of the course, don't be discouraged if you don't meet them all right now. The course is designed to be accessible even to beginners, and we'll be covering all necessary foundational concepts as we go. The most important requirement is a willingness to learn.
