I believe this question was asked before:

Hope this helps.

Yeah I saw that, but it's really only the definitions. I'm looking for the relationship among them.

All three are types of polymorphic DNA sequences.

Generally:

RFLP: restriction fragment length polymorphisms
VNTR: variable number tandem repeats (8 to >50 base pairs)
STR: short tandem repeats (1–8 base pairs)
SNP: single-nucleotide polymorphisms
