Answer 1

Answer:

The incorrect statement is number (2): Data marts typically have broader focus than data warehouses.

Explanation:

Data marts are data structures built on a database. In this structure, consolidated data is stored that will be used as a feed for an analysis tool. Data marts are specialized in storing data of a specific area of an organization. A group of datamarts is called Datawarehouse.

Therefore, data marts have a narrower focus than data warehouses.
