Over the past few years, the world of Business intelligence and analytics has been evolving. Traditionally, the technology stack involved in BI began with what used to be referred as data warehousing and reporting.
This has advanced over time as visualization technologies such as Tableau and Qlik began transforming the top of this stack. This transformation has gone on to the point that it's become a self-service function in the business that is no longer managed heavily by IT. This function is called self-service visualization and data discovery.
