Where are data activities?

Hi,

I am using the latest version of wf, but I couldn't find the data activities (WaitForData,WaitForQuery,UpdateData, andSelectData). I want to integrate InfoPath 2003 with windows workflow foundation by using data activities.

I want the user to design his own form then consume the form's data in workflow as schema file (xsd)

How can I use the functionality of those activities for this version?
