Since AJAX provides connection between Client-Side and Server-Side, will there be any effect on the performance of Database if the request was accessing DB. Eg: In Gmail when I type in a persons email address I get a drop down with all the like email(s). If I were to access DB for this kind of feature will it effect the performance of DB?

Since all of the DB access will be on the servlet side of your application and not in JavaScript on the browser, the performance on the servlet will only be
effected by any changes that you need to make to build and pass the XML back to the AJAX app on the browser.
