[GRASS-user] grass vector model, cats and layers concept

[Vincent Bain]

Hi dear GRASS users,
I resume this pretty old topic with a brief new section to the Wiki :

http://grasswiki.osgeo.org/wiki/Vector_Database_Management#Grass_vector_management_model

I did only add the section named "GRASS GIS vector management model"
without modifying anything to the rest of the page (you'll probably
notice some inconstancies)

Thanks for your feedbacks on this section,
Vincent.
