Hi to All
 
In this last threads we are discussed also about classification
(phylum,class,order ecc.)
I have doing a msaccess Database of shells, and I have done also
a part regarding the classification, but I have several doubts.
 
I have done the table of Class,Subclass,Order,suborder,SuperFamily,
Family,SubFamily with referential integrity.
 
Now I have supposed that the subclass & Suborder could be also not
present, thus I have linked in the Table Class the Order
and also the Subclass..
 
My doubt is: each genus has a classification with all this
this categories or some genus don't have for example the subFamily
or suborder?
 
In some books I have seen also for example SuperOrder and Tribus, do you
think that this informations could also be useful to insert
or not?
 
Can anyone light up and give suggestion about a logical structure
regarding the classification?
 
Thanks
