Hi Gustavo,
you need only one entity.
Area:
area_pk
parent_area_fk
foo
Now you build a relationship area_pk <->> parent_area_fk.
So each area can have many 'subareas' while one are has only one parent
area.

Hello Im doing an eomodel.. .and I have an entity called Area, and
SubArea, for me an area can have many subareas, but subarea its an
area itself also..
so its like Area <- >>SubArea.
Now what are the implications of defyning Area with its properties,
and then SubArea and put as parent Area?... I see that inside Area
Entity there is SubArea Entity also... but I guess this doesn't
guaranties me the to-many relationship between the 2 entities isn't
it?do I still have t defying the relationship?
Thanks
Gustavo
