SOA。 企业组件到底是什么？它如何反映服务？

Question

I have been trying to draw SOA layers diagram with Visio 2013, but cannot figure out the "Service Components" naming convention. How components should be named deeply in details? Should it be named technically?

Consider this:

Service layer: car information search

Operations: get car information by code, get car information by holder, etc

Service components: How to name it???

If someone can upload exact real world example of SOA layers, it will be the most helpful thing

It's hard to relate all layers to interact each other, i cannot find any real example of SOA layers diagram...

Thanks in advance

Here is what I found in terms of real-life sample:

It is from this presentation.

The description of the service component layer according to SOA RA by the open group, you can read in detail here . As I look at the architecture building blocks of this layer it seems to hold the underlying functionality/logic that enables the service to act accordingly to its contract (which is defined in the Services layer). So in your case probably you will have a Search Manager or Data Manager or Car Search Manager as a service component.

Note that most of the components in this layer are quite technical and are used in the realization of multiple services (eg Service Invoker, Service Publisher, etc.), so it makes sense to name them in a more general way (not just in the context of one service). I suggest that you dont't even include these in the diagram explicitly, unless your aim is going into great technical details.
