Data Analysis in Power BI: How to Create Dimensional Queries and Decomposition Tree
Guided project on OLTP to OLAP data transformation and Decomposition Tree using US Super Store Sales data
Earlier, for any data transformation or data conversion project, we used different ETL tools. Yes, for large-scale enterprise projects, definitely we need ETL or data warehouse tools. But, using Power BI we can very well transform any transactional data to analytical data that means OLTP data model to OLAP data model.
In this blog, we are going to learn how we can create a Star-Schema data model from a transactional data file. We will explore Decomposition Tree AI visual.
