Question

Quizplus · Accepted Answer

A data warehouse is specifically designed to store large amounts of data that have been cleaned of inconsistencies and redundancy, and are intended for data mining and analysis purposes. An operational data store is designed for real-time transaction processing and does not necessarily have the same level of data cleansing and organization. A data lake is a less-structured data repository that may contain raw or unprocessed data, while a master data store is specifically designed to consolidate and manage core business data.
