I am very new to the web design and creation. I am learning Dreamweaver and CSS at the same time to better understand the web design. I heard there is an open source program OS Commerce for web merchants. I am interested in learning that program. Since I am already in the middle of my learning Dreamweaver, I would like to know if those two programs can work hand-in-hand together. My guess is Dreamweaver is more toward web design while OS Commerce is for setting up the web merchant interface with customers (updating the products for the site, accepting the orders and payments, and etc). Appreciate comments and feedback on the difference on those two programs (or similarities).
