Structure of Databases in Management Consulting

I am trying to model a part of processes in Management Consulting. Is there anyone who could help me in understanding what type of data (a list of features) is stored in the generalist Management Consulting firm (ie McKinsey, Bain, BCG) and to what type of data these companies usually have access to (again a list of features) within their clients’ databases.
Thanks a lot.

PS is this forum a replacement of the slack channel DQ had before for enrolled students?
