It is a focused 2-month, intermediate-level program on data modelling, ETL and warehousing.

It is Intermediate level, so some familiarity with SQL or basic dashboards helps a lot. If you are a complete beginner, our Data Analytics course is a better starting point first.

Data Analytics teaches you to build dashboards from ready data. This course goes underneath that — how data is modelled, transformed with ETL, and structured in a warehouse so reporting stays reliable and scalable.

You complete an end-to-end BI project: designing a warehouse-style data model, loading data through an ETL process, and building an executive dashboard you can present.
