Learning notes — overview

This section captures Power BI concepts as they are applied in the project, written from the perspective of someone learning the tool hands-on for the first time. Each note aims to answer: what is it, why does it matter here, and how did we use it?

Planned notes

As the project progresses, notes will be added for:

• Power BI Desktop & the PBIP project format — how a report is stored as text, and why that matters for version control.
• Power Query (the "Get Data" / ETL layer) — connecting to the processed CSVs and light shaping.
• The data model — tables, relationships, and why a star schema keeps things fast and simple.
• DAX measures — from SUM to time-intelligence (TOTALYTD, SAMEPERIOD…).
• Report design — pages, visuals, slicers, and telling a clear story.

Terminology bridge

A short glossary mapping the theory terms from the intro course to what you actually click and type in Power BI will live here, so nothing feels abstract.

(Notes are filled in incrementally — see the Roadmap.)
