A _________ is a type of data store that is intentionally created for a specific business unit, usually for management and reporting purposes.

• A. Data Mart
• B. Data Lake
• C. Data Warehouse
• D. Operational Data Store

Answer: (A)

A data mart is a data store created for a specific business unit, usually for management and reporting. Because it is scoped to a single area, it includes just the data that unit needs, often pulled from a broader data warehouse or operational systems. This makes it faster to query and easier for analysts in that unit to access relevant information for decision-making. In contrast, a data lake stores raw, diverse data in native formats and isn’t organized primarily for quick reports. A data warehouse is typically enterprise-wide, designed to support cross-functional reporting and consistency across the organization. An operational data store focuses on integrating current data to support ongoing operations, rather than strategic management reporting. So the described type best matches a data mart.
