Developing a theme for Shopify is a little bit different than for something like Wordpress. First of all, you do not run a local server instance or database. I’m not sure why, but I bet it is because Shopify made a choice to reduce complexity for the entire community by hosting and guaranteeing the quality of the data model. That way, you don’t have to worry about ever updating your server.
