Quizplus · Accepted Answer

Both data warehouses and data marts are designed to consolidate information from multiple databases. Data warehouses generally contain information from various sources within an organization, while data marts are smaller, specialized subsets of a data warehouse that are created for specific departments or users. OLTPs, on the other hand, are online transaction processing systems that are typically used for day-to-day operations rather than data analysis.
