I am using version 1.3.8 (just installed) and I am wondering if it is possible to use a different database, which already has all my products in it, instead of entering every product in manually through the admin control panel?

I am using phpmyadmin and everything is the same with the existing database except the column names are different, and all of the info in is one table (category, description, title, item #, plus other custom fields).

How customizable is Zen Cart, will I be able to do this?
I'm not asking for a full step by step guide, but any help you can give me I will really appreciate.

Thanks,
John
