Data Marts vs Data Warehouses: Understanding the Difference
What is the difference between data marts and data warehouses?
1) Data marts; data warehouses
2) Data marts; data dictionaries
3) Data warehouses; data marts
4) Data warehouses; data dictionaries
Answer:
The difference between data marts and data warehouses lies in the level of control and data management.
Data Marts: Data marts support local control and are meant for specific departments or business lines. They are smaller data repositories that focus on a particular area of a business or a specific group of users.
Data Warehouses: Data warehouses, on the other hand, support central control. They are large-scale data storage systems that gather and manage data from different sources within an organization, providing a centralized view of the data.
This centralized view allows for higher-level analysis and reporting across different areas of the organization, making data warehouses ideal for organizations that require a comprehensive and unified view of their data.
Therefore, the correct pairing given the context of control is 1) Data marts; data warehouses.
