Question

Quizplus · Accepted Answer

Data warehouses are designed to maintain historical data and are optimized for complex queries, while data marts are smaller, more targeted subsets of data warehouses that are designed for real-time analytics and decision-making. Data marts typically only contain data from a specific department, functional area, or business process, and they are updated frequently to ensure that the data is as current as possible.
