Which type of data mart may span multiple business units?

The choice of a dependent data mart is correct because a dependent data mart is designed to be a subset of a larger data warehouse and relies on the data stored in that central repository. This means that it can draw from a wide range of data across different business units, integrating various departmental data into a comprehensive view. As a result, dependent data marts can provide insights that touch multiple areas of the organization, facilitating cross-departmental analysis and reporting.

In contrast, independent data marts typically operate autonomously and are built without relying on a central data warehouse. This means they might focus on a single business unit and may not encapsulate data from multiple departments. Logical data marts, on the other hand, are more about how data is structured and accessed rather than where it is stored, and they don't necessitate a relationship with multiple business units. The term "data mart implementation" refers to the overall process of establishing a data mart but does not specifically categorize it in relation to business unit integration.
