SQL for Data Science (and Version Control with GitHub)

In this module, you'll dive into the heart of SQL data manipulation, mastering essential techniques that data analysts use every day. You'll start with fundamental SELECT statements and progress to powerful data combination methods across multiple tables. Through hands-on practice with the BookCycle dataset, you'll learn to sort, filter, and aggregate data like a pro. By the end of this module, you'll craft queries that transform raw data into actionable business insights, and even explore how to optimize your queries using modern AI tools.

In this module, you'll move beyond basic SQL by learning powerful techniques like subqueries, Common Table Expressions, and window functions - essential tools for advanced data analysis. Through hands-on practice with the BookCycle dataset, you'll master the art of writing efficient queries that handle multi-layered business questions. You'll also leverage AI tools to optimize your queries for better performance. By the module's end, you'll command an advanced SQL toolkit that separates novice coders from professional data analysts.

In this module, you'll master essential data preparation and management skills - the foundation of reliable analysis. You'll learn to transform messy data into analysis-ready datasets through cleaning techniques and data manipulation operations. Working with the BookCycle dataset, you'll explore database schemas, optimize performance, and handle data across different formats. By the module’s end, you'll be able to use AI tools for optimization and integrate SQL workflows into broader data science projects.

In this final module, you'll bring together everything you've learned throughout the course to tackle a comprehensive real-world data analysis challenge. Working with the TechMart retail dataset, you'll utilize your SQL skills to clean messy data, craft complex queries, and generate actionable business insights. You'll apply advanced techniques like window functions and CTEs, optimize query performance, and leverage AI tools to enhance your workflow.
