Who is BI developer
A BI developer turns agreed measures and report layouts into working models and dashboards. They configure data relationships, write calculations, check filter behaviour and ensure correct totals. Sales amounts, for example, must remain valid when users move between stores, regions and time periods.They clarify definitions with analysts and verify sources and refresh schedules with data engineers. They also optimise slow reports and implement row-level access. The central deliverable is a dependable reporting system rather than primary ownership of business interpretation.

How to become a BI developer
Start with a data model and a simple report whose totals can be checked manually.
1. Study
Study SQL, dimensional modelling, your BI tool’s calculation language, filters, refresh processes and access control.
