Flex your muscles on Lynda.com

( I know, how many times has that /bad/bad/ pun been used? A lot +1 )

Lynda.com has recently added "Flex 2 Advanced: Using Data Services".

As shown in David Gassner's previous titles, Flex 2 Essential Training and Flex 2 Beyond the Basics, the purpose of Flex is to manage four key challenges in web development: Multistep processing, client-side processing, data manipulation, and data visualization. With the addition of Flex Data Services, Flex 2 has become an even more powerful tool for building data-drivenweb and standalone applications. In Flex 2 Advanced: Using Data Services, David discusses the program's possibilities thoroughly--from using Java Enterprise Edition to building a working database.
