Using jQuery for Database operations

Using jQuery for Database operations

Hi
I have searched similar posts and came to know that jQuery Mobile cannot connect to database like
a typical server side language.

I wanted to develop a jQuery Mobile application that performs some basic database operations
(login, fetch some data and show it in different controls (text boxes/lists/menus etc)

Now I know that we can use jQuery (not jQuery mobile) for database operations but first I have
never tried it, secondly, I dont know if I can use jQuery Mobile and jQuery to achieve my requirement.

Please help me in this regard.
