Below is the question i got in exam.
4) What are the space requirements for views? • Views require the space used to store a few records in various system tables • Views do not store data and therefore use no space • Views require as much space as would a table that presented the same data • Views require as much space as all the tables they are created from.
I maked 2 as answer, but the answer is wrong.So that means views take space in database .Is it correct ?

Yes, they do. Not for data, but for the description of the view - making answer #1 the correct one.

Additionally, some databases like Oracle support materialized views. These require space for the data as well.
