The data warehouse is a very successful implementation
of metadata management for several reasons:
??? Metadata management provides an end-to-end solution, from the logical definition of
data to the physical transformation of the data.
??? Metadata is at the heart of the operational process. By defining the source, target, and
transformation information, metadata is the main driver of the application itself.
??? Metadata provides the core documentation of the processes.
??? System integration is supported by building a semantic understanding of the data
sources.
??? Control and reliability are increased within the data warehouse development effort.
??? Flexibility is improved by integrating metadata as control mechanism.
??? Data analysis is improved by utilizing the conceptual, logical, and physical metadata
to understand the process and results.
The metadata repository allows developers, data analysts, and data administrators to view,
modify, and manage the application end-to-end. Metadata is the central point of administration
