Bill Inmon – the “father of data warehouse” – has written 57 books published in nine languages. Bill’s latest adventure is the building of technology known as textual disambiguation – technology that reads raw text in a narrative format and allows the text to be placed in a conventional data base so that it can be analyzed by standard analytical technology, thereby creating unique business value for Big Data/unstructured data. Bill was named by ComputerWorld as one of the ten most influential people in the history of the computer profession. Bill lives in Castle Rock, Colorado. For more information about textual disambiguation refer to www.forestrimtech.com. Interviewer: Rajib Bahar, Shabnam Khan Agenda: SB - In the 1970s, you have coined the term, "Datawarehouse".
