OLTP vs OLAP (Data Warehouse) as a DataSource in Analysis Services 2005

Hello,

Can I import an OLTP (Reltional DB) as a Data Source into SQL Server
Analysis Services 2005 and then use the Cube Wizard and the new Data
Source View feature to create the OLAP model ?

Or do I have to first design an OLAP Data Warehouse with a Star Schema
and then import this DW as a Data Source into my Analysis Services
Project.

With SQL Server 2000 , OLAP would be the way to go..but with SQL
Server 2005 , it seems as though the wizard and data source view
features do half the work for you.

I have an OLTP DB and am not sure which route I should take ! Any
suggestions / input would be much appreciated.

Thanks in Advance...

Regards
Russzee

Here's the followup answer to my own post...

Just what I thought...It's the new UDM all the way in SQL Server
2005 !!!

"SQL Server 2005 Analysis Services can create UDM cubes without the
intermediate step of building a star schema data warehouse. The UDM
enables organizations to build reporting applications directly against
a production system and doesn't require an intermediate data warehouse
as in the past. This is because the UDM doesn't require the data to be
in a star or snowflake schema, but can connect to any data source
whose data is stored in a third normal form. "
