Power BI is a tool for data modeling and visualisation.
It can connect to various sources like SQL Server, Vertica, Business Central etc.

But what most impressed me is the web data source. It's basically a web scraper that can extract tables from web pages. This is a very powerful feature which allows you to bring data from web pages that you can visualise and model along with your data warehouse source.
