<p>By rolling up these concerns in the framework, the implementation of the
BPEL constructs can be simpler by limiting itself to implementing the BPEL
logic and not the infrastructure necessary to support it.</p>

we'll illustrate with one complete <a href="#examples">example</a>. But if

<p>From a client standpoint, we've achieved concurrency of execution even with

event handlers and seeing that continue/listenOn is all you need. The last step
is just adding implementation details.</p>

<h3 id="channels">Channels</h3>
<p>As briefly demonstrated above, channels are interfaces used for
communication between activities in ODE engine. There are several types of
channels like TerminationChannel, ParentScopeChannel or CompensationChannel
(their respective purpose should be obvious from their name). Some basic
channels are provided to all activities when they're created to allow them to
interact with their environment. When an activity wants to notifies its parent
that it has terminated for example, it just calls its parent TerminationChannel
(see the Empty example above).</p>
