tener = "to have" in the sense of owning or possessing
haber = "to have" used in perfect tenses, as in "I have seen", without a meaning.
One huge difference is that haber is nearly always used as an auxillary (helper?) verb, like, as Lazarus mentioned, in the perfect tenses.
Haber is also used to say there are as in "hay varios aqui."
