Q1. Difference between view and m-view
Ans. 
View is a virtual table based on a SQL query, while materialized view (m-view) is a physical copy of the data from the query.
• View is a virtual table that does not store data physically, while m-view is a physical copy of the data.

• Views are updated dynamically when queried, while m-views need to be refreshed to update the data.

• M-views are useful for improving query performance by pre-computing and storing results.
