Cursor is a pointer(in c/java).Cursor work with DML and information can be accessed.
Cursor is required to process each row individually for queries which return multiple rows.
Advantages:1)We can do operations on each row.
2)Response time is good.
3)Cursors are faster than the while loop.
Disadvantages:1)Repeated network round trips.
2)Occupies more resources and temporary storage.
