There is no way of sending data to a device that is not connected. It may help if you explain a bit more.

ok. I have connected my arduino to my PC and I am sending data from PC to arduino serially using local host successfully. my problem now is when I deploy the website the arduino is not getting updates if I am not on the host PC.

have a look at the ESP8266 - you can give your arduino wifi for $5

ok. isn't there another way of doing it besides wifi on arduino, maybe something like a separate offline application where the database downloads updates on the host computer where the arduino can access.
