Materialized views is an academic concept and data management technique involving the precomputation and physical storage of the result of a query. This approach investigates the trade-offs between data redundancy, storage costs, data freshness, and query performance, characterized by mechanisms for maintaining consistency with the underlying base data. Its significance lies in enabling substantial query optimization and performance enhancement in analytical and performance-critical systems by providing rapid access to frequently needed derived data without recalculating the base query.
