David, a Lead Data engineer with XYZ company looking out to improve query performance & oth-er benefitswhile working with Tables, Regular Views, MVs and Cached Results.Which one of the following does not shows key similarities and differences between tables, regular views,cached query results, and materialized views while choosing any of them by David?

Options :

A : Regular views do not cache data, and therefore cannot improve performance by cach-ing.

B : As with non-materialized views, a materialized view automatically inherits the privileges of its base table.

C : Cached Query Results: Used only if data has not changed and if query only uses de-terministic functions (e.g. not CURRENT_DATE).

D : Materialized views are faster than tables because of their “cache” (i.e. the query results for the view); in addition, if data has changed, they can use their “cache” for data that hasn’t changed and use the base table for any data that has changed.

E : Both materialized views and regular views enhance data security by allowing data to be exposed or hidden at the row level or column level.

Answer: B
