When trying to get SQL Server samples from codeplex you may wonder where they all go. This is something i keep coming across as it is not something one does often. So here is quick guide to where to find them once installed.
Assuming you installed all the SQL server samples available, you will notice that after installing samples you will have a Start menu shortcut leading to:
C:\Program Files\Microsoft SQL Server\100\Samples
Here you will find the Adventurworks online/offline reports and other SSIS/SSAS samples.
However, if you install the Adventureworks OLTP, DW, and OLAP databases (usually if you are working with B.I.) you need to find the location of some projects in order to deploy. Now you need to look in the Toosl folder i.e.
C:\Program Files\Microsoft SQL Server\100\Tools\Samples
i have assumed a default SQL installation directory on drive C.
