Unfortunately, this human figure represented in a hologram can never return from death in the physical sense of the term. Data is an android created to demonstrate the intelligence of human society. In the episode "Datalore", Data told one of the doctors that he has an on/off switch on his back, which allows him to turn on and off. Data keeps the switch a secret because he believes the power button could be used towards his demise if he ever exceeds his limits as an intelligent android. In the episode "The Measure of a Man", Commander Riker attempts to prove during the hearing that Data was a computer by turning it off with its power switch. Although his wired insides didn't convince the judge that he wasn't human, Data later showed the judge that just because parts of his body can be unscrewed doesn't mean his internal makeup will be unscrewed. A day.
