Latest Big Data Deep Dives

20 years ago, BI was the realm of developers, with technical tools that required development effort to create BI reports for business analysts and report consumers to use.  Not much longer than 10 years ago, newer and more business-friendly BI tools appeared, led by Qlik and Tableau, that allowed business analysts to take ownership of BI report and dashboard building.  These new tools allowed business departments to own the reporting and analytics space, work quickly and in an agile and flexible manner.  This agile approach was soon picked up by the data preparation market, and business-focussed agile data preparation tools such as Alteryx appeared a few years later, to complement the agile BI tools, once people remembered that pretty dashboards are only as useful as the available data.
