I like to know what exactly is the back-end programming? Does it include offline databases? Everyone who designs and creates databases and tables is a back-end programmer? What do they mean exactly by server side programming? By which languages they do this and may someone gives some examples about some of those programs that are written for server and we call them back-end programs? Maybe its good to ask for which kind of projects/programs/applications we need back-end programming?
Sorry if this is duplicated, broad or boring, but I couldn't find my answers any other places!
