For example I've created a free software website and I've stored all the software details into my database. I also want to put a "People who downloaded this also downloaded:" or "Similar Softwares" list onto every software details page. How do I go about doing it? I don't really know what keywords I should type into google.
Ooops, sorry, I think I've posted in the wrong board, it should be in Server-Side (PHP, SQL, ASP.NET, etc.)
