Describes techniques necessary to use DEC's Rdb technology to face the challenge of the '90s—how to store data to meet an organization's decision support needs and provide users with a common, simple, transparent access to information regardless of where it resides. Contains detailed discussions and analysis of major issues including why a split between operational and informational databases is necessary and how to accomplish it, the lack of data creditability, integration of DSS data and how Rdb technology fits with DSS needs.
William H. Inmon is an American computer scientist, recognized by many as the father of the data warehouse. 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, non-volatile, 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.
