SharePoint 2010 Technical Overview
This lesson is focused on updating you on the new and improved architecture in SharePoint 2010. These changes are the foundation for many of the features and functionality you will be configuring and developing later on in the book. This will not provide an exhaustive discussion, but only touch on the major points and try to clarify where the new architecture will affect your development process when working with SharePoint Business Intelligence solutions. For an in-depth administrative look at SharePoint 2010 check out Professional SharePoint 2010 Administration.
