I am using one database for Joomla, Wordpress and Drupal.
I have a table within the database which has my data in it. The data came from CJ.
Using this csv (txt) file, you will pull the product data into the Joomla, Wordpress & Drupal systems.
A Navigation Menu will be created from one column in the table.
The product data will be displayed from other columns (image, url, description, etc.)
