Dear DP Members, I am searching for a reliable OPEN SOURCE CMS which will be a Online Product Cataloger manager. If anyone has a custom built, please let me know.
I would suggest you laook at Drupal as CMS and at the Ubercart modules for your catalogue and other e-commerce facilities. I am sure that past the initial and short duration pain with learning the framework, you will be able to build something very scaleable and very flexible.
I have a client that needed just a catelog with categories for their furniture. I used Joomla as the core CMS www.joomla.org and used Product Book extension at http://extensions.joomla.org/extensions/directory-&-documentation/directory/786/details
You could use drupal or if you have a host with fantastico enabled, they should have a shopping cart available for installation on your domain.
