anonymous block cannot be stored in database. it start with
"Declare" keyword can also contain name but that will be
temporary block. it only exist in the oracle work area for
during execution time after execution it destroy from the
memory. it cannot be called for future use.

but named block exist in the database and can be reusable.
we can call it any time it also called pl/sql database objects.
like......
procedure (it will exist in the "user_source") dictionary
view.
function (it will exist in the "user_source") dictionary
view.
package (it will exist in the "user_source") dictionary
view.
trigger (it will exist in the "user_triggers") dictionary
view.
