Business Intelligence and Data Warehousing?
lThe Data Warehouse (DW) provides access to corporate and organizational
data.The data in the DW must integrate
all potential sources of data used to make business decisions.It should be called the “truth
database” and, thus, must be THE clean, consistent
and reliable source of information for allbusiness
users.The DW is NOT a
copy of source data systems.It uses only the data elements and business
metrics required to make business decisions and contains
several years of history.It must be easy to understand and navigate for
the common business user.
lBusiness Intelligence (BI) is the
ability to turn data from the DW into valuable information used
to make critical business decisions.
