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!!
