Thank you for your quick answers, I will focus on your suggestions so I don’t get lost!
it’s for a site selling print cartridges, and I need a many to many relationship because a cartridge can be used in several printers and a printer can use many differents cartridge (originales, compatibles..).
We have bougth a database witch do the job, so I have the solution of using it next to the WP database : in that case I inject all the cartridges and the printers in the post table for the business in woocommerce but I use it for the data search, or the solution of creating a new table in wp databases witch do the job (distributes the data..), but the first database is prefect so I’d like to try to deal with it!?
At the moment this is what we have done (export and import), but I am worried that it does not work well in terms of classifications, searching and displaying results.
thank you very much for your support
