Such joins may appear in the datalayer of an OLTP schema. You should get rid of the loops/multiple paths in the modelling layer (in ALL cases)

Hi

It depends on what you're trying to achieve. In mos cases the best approach may be to have a number of start schemas with conformed dimension and possibly some snowflaking.

One of the ways to get rid of loops and multpath joins is to use aliases of the tables in the middle layer.  These are just copies of a table with a differnt name and different joins.
