Collinalitics

Power BI, SQL and Excel tutorials for the people who actually have to produce the reports.

Collinalitics is a UK data analytics channel run by Collins Ayidan, MSc Mathematics and Data Science, and founder of Collinalitics Ltd in Edinburgh.

Every video is a practical walkthrough you can follow on your own data:

- Power BI dashboards, from data model to published report
- DAX and Power Query, explained without the jargon
- SQL for pulling and shaping the data underneath
- Excel to Power BI, for teams moving off spreadsheets
- Real projects: cashflow, sales, stock and month-end reporting

No theory for its own sake. If a technique will not survive contact with messy real data, it does not make the cut.

Whether you are learning analytics or doing the reporting for a small business, you are in the right place.
