This type of modeling suggest that you can design the system visually using some form of Doodleware and then more or less generate the code for the running system.

These fields are very useful if a SOAP message is routed through intermediaries on its way to the ultimate destination.
For example, a service
This is something that is much harder to express with line of code which are naturally linear. We can track dynamic communication between components, such as usage of  Return Addresses but avoid having to intercept every single message.
In recent years patterns have become almost the de facto standard for knowledge of these underlying principles.
However, it is important that the model is seen as an addition, not a replacement for actual code.
Much of the design of TCP is concerned with window size, the frequency of acknowledgement messages, and issues such as the Silly Window Symptom. We should have really named the Correlation Identifier, "Conversation Identifier". This type of modeling suggest that you can design the system visually using some form of Doodleware and then more or less generate the code for the running system. Instead, each carrier maintains a small number of central hubs and tries to route as many flights as possible through these hubs. If we cannot design the whole system from the top down how can we get such a visual representation?
So we expect the developer of these pieces to be fluent in OOAD, design patterns and related topics. When we examine the category "models and patterns" as it relates to integration, though, it appears to me that it requires a much broader range of knowledge. I also think the appliances have to offer an additional premium in realized benefits to justify introducing another development platform to support. Many drafts are even hosted on the vendor's site.
ConclusionA Request-Reply interaction between a service
Anyone who has tried to debug an XSL stylesheet can appreciate the pitfalls of declarative programming. In order to build such solutions, developers have to understand concepts like templates, regular expressions,  or complex functions. The few remaining weaknesses are well understood.
We should harvest it from the actual system! The second reason is that many companies do not know how to attract and evaluate hot shot developers. You could imagine the graph shown above with the X axis being the number of applications and the Y axis indicating broker or point-to-point. You could imagine the graph shown above with the X axis being the number of applications and the Y axis indicating broker or point-to-point. Two vendors specializing in this segment are Infotone and Cast Iron Systems.
I was happy to hear that Oracle is planning on building a nice documentation function that allows me to print the process with all the detailed settings.
