This answer depends on WHICH Dumbledore you are referring to. There is in fact two Dumbledores who appear in The Deathly Hallows. Aberforth Dumbledore is Albus Dumbledore's brother. He is first introduced when he sends Dobby to help Harry and friends out of a sticky situation. He also gives Harry and friends a place to hide from Death Eaters and shows them a way back into Hogwarts. Albus reappears in the story as well, but simply as somewhat of a ghost or hallucination. He is simply there to answer questions that seemed to be left up in the air at the beginning of the novel.
If you are referring to the book: Harry reads an article about Dumbledore written by Elphias Doge; Dumbledores old friend. It explains a lot about Dumbledores childhood.
