MS-CRM - Query to list the relationship between the Entities

In the recent past, I have been associated with multiple data migration projects. All of them had one thing common, the destination for all those projects was MS-CRM database. 

There were occasions when it was required to know the parent/child entity relationship before SSIS package for the migration could be designed. For this information, I used to bug CRM team of respective project every now and then, thanks to my exceptional remembering/recalling power and unfamiliarity with CRM Tool . :) 

CRM Team had enough of me one day and told me "So what you don't know CRM tool, entity relationship information can be extracted from CRM database as well." A
And it triggered me to write this script and believe me CRM Team was more happy than I was when I was done with it..

SELECT
   DISTINCT Rel.Name AS Relationname
   ,ParentEnt.Name AS ParentEntity
   ,ChildEnt.Name AS ChildEntity
   ,ParentAtr.Name AS ParentAttrbuite
   ,ChildAtr.Name AS ChildAttribute
   ,Rel.IsCustomRelationship
   ,Rel.IsLogical
   ,Rel.RelationshipType
FROM Relationship Rel
INNER JOIN Entity ParentEnt
ON Rel.ReferencedEntityId = ParentEnt.EntityId
INNER JOIN Entity ChildEnt
ON Rel.ReferencingEntityId = ChildEnt.EntityId
INNER JOIN Attribute ChildAtr
ON ChildAtr.AttributeId = Rel.ReferencingAttributeId
INNER JOIN Attribute ParentAtr
ON ParentAtr.AttributeId = Rel.ReferencedAttributeId
WHERE ChildEnt.Name = 'customeraddress' ORDER BY ParentEntity
