In the company studied, business units that accessed their data through data marts were usually more successful than units that accessed it through a single repository.
That is, most units either requested a data mart, or simply did not use the single repository.
Data marts help reduce the inherent complexity and ambiguity associated with data warehouses by providing a slice of the data that is tailored to meet the specific requirements of a business unit.
However, one of the most successful uses of this data warehouse was through a single repository.
That unit had a strong need for a very broad range of data as well as contextual characteristics that distinguished it from the units that used data marts.
In particular, people in that unit were proactive in trying technology.
As a result, they were not intimidated by technology and were generally technically knowledgeable.
