What is the difference between views and materialized views in databases?
An example of an AI chatbot conversation about views vs materialized views in databases.
What is the difference between views and materialized views in databases?
Views are virtual tables that display data from one or more tables, while materialized views store the data physically.
Can you explain how performance differs between the two?
Sure! Views are always up-to-date but can be slower to query, while materialized views are faster but need to be refreshed.
When should I use a materialized view instead of a regular view?
Use a materialized view when you need faster access to data and can tolerate some delay in data freshness.
Are there any downsides to using materialized views?
Yes, they require more storage and maintenance, as you need to refresh them periodically to keep the data current.
