RE: Which is not the characteristic of a view ?
 

correct answer is


a) Consumes Disk space for data

BECAUSE VIEWS ARE THE VIRTUAL TABLES WHICH FORMED ON THE EXISTING TABLES OF DATABASE, SO IF WE DO ANY TYPE OF CHANGE IN STORED DATA THAN THIS CHANGE IS MADE UP ON ORIGNAL TABLE NOT IN VIEW,ON THE DISK NAME OF VIEW IS STORED ONLY SO IT COSUME SO LITTLE SPACE.
