[Users] object with multi sub object

[François Boussuges]

Hello.

I have a problem in the conception of my application (oracle+ geoserver+ 
geoext).

I have a database with:

-sites: a lots of site with lon/lat.
-accession: accession is an object on the site, one site can have 
several accession (ex: the site DBS33562 have 8 accessions)
-a lots of attributs : each type of accession (the type is : grapfruit, 
corn, vegetables...) have a lot of attributs (ex: for the grapfruit: 
color of the fruits...).

In m'y map i need to see each accession and this attributs when I click 
on a site.

I think to solutions:

-display the site but i don't know how to display more than one 
accession by site (I'm in training).
-display each accession individually but I have a lot of points with 
same coordinate (lon/lat).


How do you think about this? what is the solution to my problem?
If I want to display a Gridpanel with my accession when I click on a 
site what should I do?

With my best regards.

François
