Referential indexes

Hi all

Got this query from a developer, or actually they are actually arguing with the DBA team.

Table A - master, acc number field also only column in PK

Table B - Child, acc Number Field acc number is the first column in PK, PK contains 2 more columns.

DBA's are saying we don't need a normal non unique stand alone index on the acc Number field for table B.

Developers want a separate index,
