To answer this question, you need to understand the concept of datamarts and the term "stovepipe."
A datamart is a subset of a data warehouse that is focused on a specific area or department within an organization. It contains a collection of data that is relevant to that specific area.
The term "stovepipe" in the context of datamarts refers to the isolation of data within a specific datamart. It means that the data in the datamart is not easily accessible or shared with other datamarts or systems. This isolation can lead to data duplication, inconsistency, and limited integration with other parts of the organization.
Therefore, the correct answer is:
B) Isolated data - This option is correct because "stovepipe" in the context of datamarts refers to the isolation of data within a specific datamart.
