Tizen Developers

# Tools for Tizen TV application development is HTML,CSS,JS. So, sure you can use them.

   You cannot use 'php' in Tizen TV, 'php' is generally used for Server side Programming.

# To connect with a existing remote DB and read/write data from a Tizen TV application:

 - You can a write a server side application (may be using php or node.js) that may respond with a JSON / SOAP message when a Http request is send to it. (On  Server PC, not tizen stuff)

- Then Send a XML Http Request or jquery AJAX request from your Tizen TV Web app to get data from DB or to set data on DB . (Client side: Tizen TV app)
