Calculated Fields, KPIs and Drill Downs in BI in Data Analyst
Think of this chapter as a classroom explanation written in simple language, with the goal of making the topic practical instead of theoretical.
Chapter Overview
KPIs become more valuable when users can click, drill down, and move from summary to detail. BI tools support this through calculated fields, measures, filters, and interaction design.
Example Use Case
A manager sees total revenue on the first page, clicks a region, and then drills into category performance and store-level detail. This journey turns a static report into a practical decision tool.
Design Principle
Drill-down should reveal more meaning, not more confusion. Keep the hierarchy logical: year to month, region to city, category to product.
Student Outcome
When you understand calculated fields and drill-down flow, your dashboards begin to feel professional and job-ready.
