efficient and successful business intelligence and reporting system in place, having a
unified perspective of the companys data is imperative. Without an overview of the entire
business, the ability to make sound judgments is lost. Without a global view of a customer
it is not possible to provide the optimal service. Without corporate consolidated spend,
negotiations with suppliers are weaker. The bottom-line is that without integrated
company-wide information, business decisions are uninformed decisions.
Reasons for the Information Integration Challenge
Providing a united view of the companys information assets to underpin business
intelligence is what information integration is all about. IDC has identified a core set of
requirements that information should comply with to form an appropriate basis for
Business decisions. These are:
Correct : Invalid data must not be permitted.
Complete : All the information relevant to the decision should be available.
Current : The information should be sufficiently up to date for the purpose, and
increasingly this means real-time currency.
Consistent : Where information is drawn from different sources, each source should
represent the same version of the truth.
While this might seem obvious, the scope of the challenge is considerable. The world of
today is characterized by constant change, and getting data that is correct, complete,
current and consistent is becoming increasingly difficult. This business reality requires
companies to embrace diversity and make the assumption that they and other companies
are constantly evolving. It is this reality of continuous change that places the extreme
demands of information integration on global organizations today.
Large companies with subsidiaries in many different locations usually operate as a group
of local units. Information is stored and managed in databases and packaged applications
such as ERP systems that have been bought from multiple vendors or custom-built to meet
the specific information management needs of the local subsidiary. These information
systems will evolve independently of one another to reflect changes and developments in
the local organizations. Trying to get a unified point of view of all systems is the most
important confrontation. The result is likely to be inconsistent reporting because of
