What are some practical use cases for materialized views in databases?
Materialized views are great for improving query performance, especially in data warehousing. They can pre-compute and store complex joins and aggregations.
Can you give me an example of a specific use case?
Sure! In a sales database, a materialized view can be used to aggregate daily sales data, allowing for faster reporting and analysis.
How do they differ from regular views?
Regular views are virtual and do not store data, while materialized views store the result set physically, which speeds up access.
Are there any downsides to using materialized views?
Yes, they require storage space and need to be refreshed to stay updated, which can add overhead.
