$\begingroup$ Can you please provide a citation and link to the resource which uses this term? Google doesn't appear to believe that "nonreductive database" is a real phrase. $\endgroup$– Sycorax ♦Mar 4, 2014 at 16:31

If your instructor told you that I think they are wrong.
This link http://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Web&PAGE_TYPE=BlastDocs&DOC_TYPE=ProgSelectionGuide at Table 2.1 has:
nr Non-redundant GenBank CDS translations + PDB + SwissProt + PIR + PRF, excluding those in env_nr.
suggesting that nr meand Non-redundant, not nonreductive.
