DMV- MDSCHEMA_MEASUREGROUP_DIMENSIONS

Here is the description for the respective columns in the DMV object  ‘MDSCHEMA_MEASUREGROUP_DIMENSIONS’.  Ref-http://msdn.microsoft.com/en-us/library/ms126192(v=sql.100).aspx

DIMENSION_CARDINALITY

The number of instances a dimension member can have for a single instance of a measure group measure. Possible values include ONE and MANY 

MEASUREGROUP_CARDINALITY

The number of instances a measure in the measure group can have for a single dimension member. Possible values include ONE and MANY

DMV query output

DIMENSION_CARDINALITY-->MANYand MEASUREGROUP_CARDINALITY-->ONE

How can we read this information? In the cube, therelationship between the Fact and Dimension is ‘Regular’ and the underlying the Dim-Fact table (Relational Database) has the‘1-Many’ relationship.

I am little bit confused and read the above output as ‘Many-1’ relationship. Appreciate your help!

Thanks in Advance!!
