SQL and Python Foundations for Data Work

Working with data requires two essential capabilities: extracting information from relational databases and transforming it using code. This text-based guide teaches you both skills side by side, providing a solid grounding in database querying and fundamental programming concepts. You will read structured explanations and analyze real-world code snippets to build confidence in managing and analyzing data workflows. What you will learn: Understand core database terminology, table relationships, and relational schema structures. Write clean SQL queries using SELECT, filtering conditions, table joins, and aggregations. Learn Python syntax basics, including data types, variables, loops, functions, and virtual environments. Connect Python scripts to relational databases to execute automated queries and retrieve results. Apply modern data handling techniques to clean, transform, and format datasets efficiently. Practice secure data querying practices, including parameterized queries and safe data handling. The curriculum starts with essential database and programming concepts before progressing into joined data queries and integrated Python scripts. This course is designed for absolute beginners with no prior coding or database experience. Read through the lessons and establish your foundational data querying and programming skills today.
