I think, discovering data patterns is about studying the problem
domain, and preparing some kind of ER model (a logical data model) to
start with. We can then prepare a physical data model from a logical
model. The physical data model is targeted for a RDBMS schema, a XSD
schema or whatever storage we are interested in.
