CDI: Learn the way real work is done

Complex Data Insights
Practical guides for complex data. Clear steps. Confident decisions.

CDI is a structured learning platform for people who want to move beyond tutorials and build real analytical skill. Learn Data Science, Visualization, Machine Learning, and Applied Bioinformatics through workflows that emphasize what to check, why each step matters, and how to interpret results.

Best starting point: Begin with the Free Edition. Upgrade to Premium when you want the full guided path.
Free Edition: complete, openly accessible tracks hosted on CDI learning sites.
Premium Edition: expanded guide editions with deeper coverage and structured progression, available in the CDI Shop.

What you get from CDI

CDI is built for independent learning: structured steps, real datasets, and decisions you can justify.

Each guide is designed to help you understand: how data is structured, what to check, what to trust, and how to explain your results. You can follow a clear path or specialize by domain when you are ready.

Recommended path: Start with Foundations, then expand into Visualization and Machine Learning. Choose Databases & SQL and Applied Bioinformatics as specialization tracks.
