Website Design

Ajax is not used for making your own database, it can be used for making calls to a script/webservice/database api that sends back info it fetches from a database however.

For my use it wouldn't be any different than using PHP w/ MySQL, just saying, and PHP is quicker, let alone it's server-side so client computers don't have to work as hard.

Do whatever is gonna work for you man, I'm not here to argue with you. You could call a php script that accesses a MySQL database too, and your points about speed are not really correct, Nodes.js typically runs faster than php, which is a pretty slow and crappy language. Really though, whatever you're going to be productive with is what you should use, because it probably won't make a difference unless you have tons of visitors to your website.
