William H. Inmon (born 1945) is an American computer scientist, recognized by many as the father of the data warehouse. Bill Inmon wrote the first book, held the first conference (with Arnie Barnett), wrote the first column in a magazine and was the first to offer classes in data warehousing. Inmon created the accepted definition of what a data warehouse is - a subject oriented, nonvolatile, integrated, time variant collection of data in support of management's decisions. Compared with the approach of the other pioneering architect of data warehousing, Ralph Kimball, Inmon's approach is often characterized as a top-down approach.
W. H. Inmon was born July 20, 1945 in San Diego, California. He received his Bachelor of Science degree in Mathematics from Yale University, and his Master of Science degree in Computer Science from New Mexico State University.
He has worked for American Management Systems and Coopers & Lybrand before 1991, when he founded the company Prism Solutions, which he took public. In 1995 he founded Pine Cone Systems, which was renamed Ambeo later on. In 1999, he created the Corporate Information Factory Web site to educate professionals and decision makers about data warehousing and the Corporate Information Factory.
Further Inmon was the creator of the Government Information Factory, as well as Data Warehousing 2.0. Mr. Inmon is a prolific author on the building, usage, and maintenance of the data warehouse and the Corporate Information Factory. His books include "Building the Data Warehouse" (1992, with later editions) and "DW 2.0: The Architecture for the Next Generation of Data Warehousing" (2008).
Inmon's association with data warehousing stems from the fact that he wrote the first book on data warehousing he held the first conference on data warehousing (with Arnie Barnett), he wrote the first column in a magazine on data warehousing, he has written over 1,000 articles on data warehousing in journals and newsletters, he created the first fold out wall chart for data warehousing and he conducted the first classes on data warehousing.
Recent advances by Inmon include the creation of DW 2.0 - the definition of the next generation of data warehousing. In addition Inmon was the creator of the corporate information factory (the "cif") which describes the larger information architecture into which warehousing fits. More recently Inmon has developed the technology for including unstructured textual data into the data warehouse - the world's first "textual ETL".
In 2012, Inmon developed and made public technology known as "textual disambiguation". Textual disambiguation applies context to raw text and reformats the raw text and context into a standard data base format. Once raw text is passed through textual disambiguation, it can easily and efficiently be accessed and analyzed by standard business intelligence technology. Textual disambiguation is accomplished through the execution of textual ETL.
