If you were up for dealing with the database, then it's very easy to find out what is where by simply looking, i.e. with phpMyAdmin.
You'd see that all HikaShop tables are named (prefix)_hikashop_(table name), indeed. And that the tables are named logically after their content, i.e. "product".
So, by only looking at the database, you can answer your question yourself. Just be careful with doing anything with or inside the database. You can imagine that it's also very simple to break your site. In any case: backup, backup, backup.
