Watch the 2nd video from Andrew Connell on SharePoint 2010 Data Access:
DevExpress Webinars - SharePoint 2010 Data Access w/Andrew Connell
Intermediate Level - Data Access
This video follows up on the "Introduction to SharePoint 2010" video and dives into different Data Access scenarios of SharePoint 2010.
I recommend watching both videos to get a good understanding of overview of SharePoint 2010 and Data Access.
