I'm developing ground up an ecommerce module and I chose the route to
just use a MENU_CALLBACK to display products.
Up to my understanding if I had used "plain" nodes I'd have gained
comments and taxonomy but still I'd have to do a lot of customisation.
If you're not going to edit products inside drupal there is no need
to go the CCK way and the custom node type route doesn't give any
advantage compared to just using different templates if you've
different product lines.
Taxonomy too is "too general" and may have a huge performance impact
once your catalogue is 500K-1M items divided in several thousands
Since editing was not going to happen in drupal, linking products and
categories to nodes and taxonomy would have made syncing the back-end
with the front-end too complicated, especially if you're going to
make a catalogue update 1 or twice a day.
Furthermore I had to use a lot of pk/fk data integrity logic that
didn't fit into node too well.
Still drupal has plenty to offer: theming, table sort, fapi, block
I do think I'll still be able to use drupal infrastructure for adding
comments to "non-nodes" somehow... but it is not a priority.
I do think that having a more complex category system is important
and drupal taxonomy could offer some inspiration if not code, but
planning a more complex categorisation system is out of my reach now
and taxonomy as it is doesn't offer anything I could really exploit
now but impose a too high toll in terms of performances and
If I'm going to glue taxonomy with the catalogue I'll have to beef
up/specialise taxonomy to really take any advantage from a more
complex system and right now I can't.
Consider that if you don't have synonyms, multi-categorisation etc...
coming from your back-end, feeding this extra data to drupal for
several thousands categories and 500K products is not going to be
Not really to much to wait to see if this pig can really fly...
