native is  used whenever you have your underlying database handling the primary key generation. Hibernate choose itself a best way to generate id according to database it is interacting with

whenever you are confused which generator to choose, give a try with native.

use assigned whenever you have own style of generating ids. Sometimes whenever i've random data in my table and hibernate is unable to identify pattern for generating next id, i use assigned so that i can manually generate my ids and supply it  for persistence.

Remember, if you haven't chosen any generator you have supply it by yourself i.e. assigned is a default generator.

>>>>>>its there

assigned       lets the application to assign an identifier to the object before save() is called. This is the default strategy if no <generator> element is specified.
