Send DATA to database from arduino (not local database)

xSeriaLx:
my project is a "smart house" i want to control the door of a house with arduino with ethernet shield and send data from arduino to a hosted database .

  1. How to send data to my database ?

*Is there any other idea to my databse ?

You can send the data to Excel. This is done with a free macro PLX-DAQ. Here is some background

The connection is by USB cable, no ethernet needed, and the method is only slightly different form sending data to the serial monitor. There are other options to Excel too.

can i put it in the sd card and send data to the sd card

Yes. You can either

  1. Send data direct Excel
  2. Send data to SD for subsequent retrieval
  3. Both

If you are serious about what you are doing, it is always a good idea to send data to on-board SD, if only for backup.
