You can do by using action attribute of apex:page 
Write your logic in method doAction.  
<apex:page action="{!doAction}" controller="ControllerName">
Note - If you are working for app then this is not recommneded in term of security.

DML can be also perform by using JS remoting when page is loaded or you can also call a method by using actionFunction from java script while page is loaded.
