MSM Full Step by Step Guide

Is there a full step by step guide for using MDM for data consolidation/harmonisation?

So far There are reference guides, which shows you each component of the various MDM applications but nothing that gives a full start to end scenario.

For example If I have Master data source from few different sources (tables), How can I compare the (records) values from the 3 sources and produce one output file by using MDM?
