Difference between Namespace and Folders

Re: Difference between Namespace and Folders in Frame work Manager « Reply #1 on: 24 May 2012 10:00:04 am » There are lots of posts and information about best practices regarding namespaces and modeling such as having a physical layer, etc. I suggest you review the FM user guide and related best practice documents to get a better understanding of the concepts.

In simplest terms, a namespace becomes part of what identifies an item while a folder does not.

In the relational world an item is identified as:

[Namespace].[Query Subject].[Query Item]

In the dimensional world an item is identified as:

[Namespace].[Dimension].[Hierarchy].[Level]

You can organize things into folders but it doesn't affect how an item is referenced. This means you could have a query subject or a query item with the same name in two different namespaces. If you had a single namespace and only folders to organize things then every name has to be unique.
