Data Warehousing Questions
Data replication in data warehousing refers to the process of creating and maintaining multiple copies of data across different systems or locations within a data warehouse environment. This is done to ensure data availability, improve performance, and support data integration and analysis. Replication helps in distributing data across multiple servers or nodes, allowing for faster access and reducing the risk of data loss or system failures. It also enables data synchronization and consistency across different parts of the data warehouse, ensuring that all users have access to the most up-to-date and accurate information.
