Installing SQL Server Reporting Services
来自MSDN文章Considerations for Installing Reporting Services：
Select Database Engine Services in the Feature Selection page to host
the report server databases. Reporting Services requires a local or remote instance of sql Server 2005 or sql Server 2008 Database Engine to host the report server databases. If you install an instance of the Database Engine concurrently with Reporting Services,you can eliminate a post-Setup task by installing the default configuration,which creates and configures the report server databases automatically. In addition to hosting the report server databases,sql Server relational databases can also be a source of data for reports and models.
