Alternatives to database in Ajax 
I am new to Ajax programming and I have been told that there are alternatives to using a database in Ajax if optimal speed is required. If there are going to be like a hundred requests per second then using a database does not make much sense. So what are those alternatives ??

I NEED ONLY "NATIVE" AJAX SOLUTIONS .. NO LIBRARIES PLEASE ..
