Metadata is one of the great buzzwords of data warehousing. Vendors of warehouse tools describe how they use metadata to control the entire build and populate process. Vendors of end user tools promote the use of metadata by users. Various gurus and consultants talk about metadata as the philosopher's stone, capable of transmuting base data into precious information and even knowledge.
