Cursor is a database object even it is treated like a data
type. It is generally used for fast and resource efficient
programming. Cursor wont fetch all datas resulted from a
select statement. Only one row at a time. this speeds up
the population of the data. In select statement all datas
shud be fetched to the client machine. Few drawbacks are
there with cursor but in some cases it works well.
