In-Depth Information
6. An open mind will be needed when reviewing for compliance
and the possible need to broaden the existing architecture or to
consider possible exceptions.
7.
Phase-out plans will need to be developed.
8.
An inventory of who is using what architectures will be required.
Guideline 4:
Organizations should leverage a data warehouse and data
marts to facilitate the sharing of existing information. This data
warehouse will contain the one single version of the truth.
1. Data warehousing must become a core competency of IT.
2.
Data warehousing requires and supplies configuration standards;
these standards will need to be developed and maintained.
3. End-user tools must be provided to relieve the burden on pro-
grammers to provide this functionality.
4.
End users must become more knowledgeable about the informa-
tion available to them. This can be accomplished by increasing
end users' awareness of and knowledge about the tools they need
to access and analyze this information.
5.
The processes and procedures refreshing the data warehouse will
require high levels of reliability and integrity.
6.
Warehousing is not meant to replace shortcomings in transaction
applications. Guidelines on maintaining data and data retention
will need to be developed.
7.
Not all requests for data are simple in nature and appropriate for
end-user tools. Not all data will be available to all users.
8.
End users should be able to access the data without knowledge of
where it resides or how it is stored.
9. Data warehouse architecture design will require an integrated
design effort to provide usefulness. The full potential of a data
warehouse will not be realized unless there is full participation
throughout the enterprise.
10. The user community must be made aware of the (un)timeliness
of information.
Guideline 5:
IT systems should be implemented in adherence with all
security, confidentiality, and privacy policies and applicable legal
and regulatory requirements.
