The purpose of this book is to document the methodology and
chronology of work activity used by the author to successfully
implement a Data Warehouse. Each of the eleven steps of the
methodology is reviewed in the book, often using actual working
documents as examples. The book contains lessons learned (both good
and bad) as well as measures of success for each step. An essential
aspect of DW project implementation (and other IT projects as well)
is using established business practices to manage development and
implementation. Discussion of use of these "due diligence"
practices in Step 1 establishes the foundation for starting the DW
project with the proper levels of management oversight. Step 2
presents examples of business models necessary for the DW developer
to understand the needs of the business that the DW will serve.
Other DW books describe the data modeling process but neglect to
provide modeling instruction and actual examples to insure that the
DW is properly aligned with business needs. An elegant data
warehouse that doesn't meet the needs of the business is wasted
effort. Step 3 documents and displays the level of detail needed to
define CSF's (Critical Success Factors) and KPI's (Key Performance
Indicators). If calculations for these important metrics are not
defined in detail, and consensus to use them is not reached, then
again, the most elegant data warehouse implementation is a wasted
effort. In addition, developing and documenting functional
requirements is essential in identifying legacy system reporting
deficiencies. Step 4 describes how to access and display field
level information on the iSeries platform. Actual shots of the
resulting screens are shown. Step 5 presents the functional
contents of an RFP for a Data Warehousing tool-set. Step 6 presents
the progression of work required to build a data warehouse. Step 6
also: A. Describes and displays a hybrid dimensional to flat file
data model that may be, in reality, the
