    If historians were fair and accurate, the names ‘Devlin and Murphy’ would be peers to Vannevar Bush, Ted Codd, and Chris Date. Barry’s early data warehouse architecture fueled a $140B industry for the last 30 years. Yet Barry is that rare individual who keeps inventing new technical insights year after year. Listen, then listen again when he speaks. This humble man with a great sense of humor is always amazing me and making me try harder.

    Barry delivered the opening keynote of the Gurus Of BI (GOBI) 2014 conference, Norway’s largest BI & Analytics conference. Drawing on his book “Business unIntelligence”, Barry presented a novel architecture, combining the strengths of traditional business intelligence with the opportunities of analytics, big data and the internet of things. As one of the founders of data warehousing, his emphasis on the people aspect should be noted by everyone hoping to succeed with BI and data warehousing. Barry continued to inspire in a full day post-conference seminar, making all attendees question their current DW architecture. Thought-provoking stuff!

    Barry brings to his projects the rare combination of (1) staggering technical depth, (2) great listening skills, and (3) the ability to envision a future and articulate it in meaningful terms to regular folks. It’s rare to find someone so well versed in how things are done today who is also completely unwedded to the status quo. Barry is that guy. If you want to think big about how to create competitive advantage, while ensuring that the plan still maps practically from a starting point of the way people and tech actually work — Barry is invaluable.
    Scott Davis, Enterprise Data Integration, Strategic Analytics, & Collaboration
