What are the Characteristics of data warehouse?

Data warehouses are characterized by their subject-oriented nature, meaning they organize data around key subjects rather than specific applications. They are designed for query and analysis rather than transaction processing, featuring a centralized repository that integrates data from various sources. Additionally, data warehouses typically support historical data storage, allowing for time-series analysis, and employ a schema design, such as star or snowflake schemas, to optimize data retrieval. Lastly, they generally provide high performance for complex queries and reporting.
