How to get the data set of NDC.RxNorm,ATC ATC to realize the mapping from ndc to ATC.

‘’‘ndc.vocabulary_id as vocabulary1_id
, ndc.concept_class_id as NDC_class_id

I also hope to realize the mapping from ndc to ATC.
Thank you very much for your understanding. Thank you very much for your understanding. May I ask you a favor? I haven't found these three datasets for a long time. Where can I get them?
