added article model

i'm not sure how to proceed storing the articles.  
do i do something like:
    article_storage_place = []
    @news.each do |article|
        if (link["href"] =~ /http(.*)/) && !link.text.blank?
            article_storage_place << article
        end
    end

shouldn't my schema have some sort of 'article id#'?

thanks.
