Importing data in Drupal7 database.

For a website project on Drupal 7, we need to import many product data in the database. We already have built all content type fields and taxonomy terms in Drupal. We have tried some modules like “Feeds” and “Migrate” to import all the data but none of them are working properly. We try to import data with phpmyadmin but it has created another table instead of fill in the existing one. We don’t know either how to link product with the taxonomy terms in the database. Data are building like this: A product has several fields: Product reference – Product name – Product market ( Taxonomy term ) – Product family ( Taxonomy term ) – Product solution ( Taxonomy term ) – Product description – Product options ( Several options ) – Product models ( several models ) – Product image Some of those fields will be empty at the importation. We need someone to import properly data and explain us how it works with Drupal.
