Answer: A
Quality of the metadata is the most important element in the
design of a data warehouse. A data warehouse is a copy of
transaction data specifically structured for query and
analysis. Metadata aims to provide a table of contents to
the information stored in the data warehouse. Companies that
have built warehouses believe that the metadata is the most
important component of the warehouse.
