Data Warehouse Metadata

It is a common belief that in order for the data warehouse to be successful, it must be metadata driven.
Our beginnings here at InfoLibrarian™ started with the data warehouse back in the 90's. We knew then and still believe today, that organizations will benefit from a comprehensive view of their metadata, and of metadata management.
InfoLibrarian's software was first released to address the need for metadata for the data warehouse, today; our products address the full range of purposes to deliver reliable metadata, especially for the data warehouse.
