Schema diagrams are available for the following sample databases for SQL Server 2005 and SQL Server 2008:
Other versions of these schema diagrams can be found by browsing into the Schema Diagram folder on the Source Code tab. Because CodePlex blocks download of Microsoft Office Visio diagrams directly from the source code browser, they're attached below.

Correct me if I am wrong. In the file AdventureWorks2008_Conceptual.vsd(AdventureWorks2008EntityModel) there is an error with the association between BusinessEntity and BusinessContact. The problem is the multiplicity at BusinessEntity side must be "1" not "*". See the picture here: http://i52.tinypic.com/mct2mc.jpg

In the AdventureWorks2008.vsd file (when you click on the "Page Info" link above), the Sales.CountryRegionCurrency cross-reference table (which maps ISO currency codes to a country or region) is still missing from the AdventureWorks OLTP schema diagram.
