What is BPEL flow?

You can create a parallel flow in a BPEL process service component with the flow activity. The flow activity enables you to specify one or more activities to be performed concurrently.

What is the difference between partner links and partner link types?

It is easy to confuse partner links and partner link types, however: Partner link types and roles are special WSDL extensions defined by the BPEL specification.
