To be more efficient we should only track subscription and publication requests.

Asynchronous architectures do not provide such mechanisms so that we
have to track state and return addresses ourselves. Because a
request-reply service component has to gain access to a queue for every
reply message the default approach would send a publication message to
the visualizer for every message.

These suites typically include visual transformation editors, workflow
or orchestration editors, schema editors, component assembly tools and
the like.

Anyone who has tried to debug an XSL stylesheet can appreciate the
pitfalls of declarative programming.

This time it is not a physical component, but a Canonical Domain Model
that is common between all participants. However, if we face a
performance bottleneck or detect invalid messages it would be
tremendously useful to know where messages actually come from and where
they are headed. The area in the middle of the picture above describes
the area where there is no clear cut answer unless you know the history
of the system you are observing. What Makes a Good Integration
Developer? until you realize you need fresh water andyou can only get it

Most of these specifications are no standards at all but rather
proposals drafted by a specific group of vendors.

In fact, there are a number of striking similarities between the two
technologies.

We should have really named the Correlation Identifier, "Conversation
Identifier".

Interestingly, in this context patterns have almost become the victim of
their own success. It will be interesting to see what the appliance
vendors find.

However, not all queues a component interacts with are known up
front.

I enjoy sketching and holding facilitated workshops where I draw system
diagrams on a whiteboards based on user feedback. a service that in turn
accesses another service.
