Dr. Barry Devlin is among the foremost authorities in the world on business insight and data warehousing. He was responsible for the definition of IBM's data warehouse architecture in the mid-1980s and authored the first paper on the topic in IBM Systems Journal in 1988. He is a widely respected consultant and lecturer on that and related topics, and author of the comprehensive book Data Warehouse: From Architecture to Implementation.
Devlin's interest now covers the wider field of a fully integrated business, focusing on informational, operational and collaborative environments and, in particular, how to present the end user with a holistic experience of the business through IT. Those aims, and a growing conviction that the original data warehouse architecture struggles to meet modern business needs for near-real-time business intelligence and support for big data, drove the thinking that went into latest book, Business unIntelligence: Insight and Innovation Beyond Analytics.
Devlin has worked in the IT industry for more than 30 years, many of them as a distinguished engineer at IBM. He is now founder and principal of 9sight Consulting, specializing in the design and the human, organizational and IT implications of deep business insight applications.
