Newbie here with, what I hope is not a really dumb question.

I have already imported a lot of data, using Store Manager, and am
looking at a more cost effective solution (my client is balking at
paying for the license).

I would like to use phpMyAdmin to import data to my database.
When I log in and select the database, I can then select the
categories table. No problem! However, if I want to import
data into a specific category/subcategory, say one with ID # 153,
do I simply check that ID and then proceed with Import? I don't
want to import data and have it go to some unknown location,
possibly messing up the whole structure.

Thanks for the assist!
