A data warehouse is designed to support data analysis and decision-making by integrating data from various sources into a central repository.

Data mining is a process performed on data stored in the data warehouse, not a component of the warehouse itself.

A data warehouse offers multiple benefits, including improved data quality, enhanced data security, and faster data retrieval.

The star schema is a widely adopted data model in data warehouses due to its simplicity and ease of use.

Data integration involves combining data from multiple sources into a unified and consistent format.

ETL tools are specifically designed to extract data from various sources, transform it, and load it into a data warehouse.

Data analysis involves examining data to extract meaningful insights and patterns.

Data visualization tools help users create visual representations of data to make it easier to understand and interpret.

Data mining involves using algorithms to uncover hidden patterns and relationships in data.

A virtual data warehouse is not a physical data store but rather a logical representation of data from various sources.

Data summarization involves reducing the amount of data by creating a concise representation of the original data.

A data warehouse aims to simplify data management and reduce complexity, not increase it.

Data validation involves verifying the accuracy and consistency of data before it is loaded into the data warehouse.

A hybrid data warehouse is not a common architecture; it typically refers to a combination of centralized and distributed data warehouses.

Data distribution involves moving data from a central data warehouse to smaller, focused data marts.
