First, how is that a "combinatorial explosion"?
Second, I offered 2 solutions. The above was only one of them. If the
quantity of attributes changes often, then the 2nd solution would
probably be better.
(I'll reply to other issues later)

The meaning I want to convey is :
provides 1..*
ServiceProvider ----------------- Service
So C is an instance of ServiceProvider.

The meaning of »service« you refer to seems to be:
»1 the action or process of serving.«

But the meaning I referred to also is given:
»5 a system supplying a public need such as
transport, or utilities such as water.«

When one implements a component C, C is a *service provider* .
When one wants to test C, the test infrastructure T that performs
said tests is a *service user* .

I now have two ideas:
When one wants to test a class or an object, one writes a
»test client«. So the class or object must be the counterpart
of a client: It is a /service/.
One also might say, that both classes and objects can receive
»messages«, so they both are /receivers/.
(I am aware, that »service« also has other meanings, as in

Responding to Daniel C...
<Hot Button>
Passing objects around like this does save some keystrokes in the short
term but it tends to lead to fragile applications that are difficult to
maintain. Passing object references is the worst form of coupling
because the receiver can do virtually anything with the object and some

Responding to Ram...
I don't think you can because classes and objects are not the same things.
Only objects abstract problem space entities. A class is simply an
identifiable set of objects. In an OO context the set itself can have
knowledge and behavior responsibilities, but those responsibilities are

You forgot already? That's how YOU would do it because you are bad at
procedural/relational programming. That's not how I did it.
There is no need to replicate shared attributes.
Without looking at something more specific, it is hard to evaluate
your claims. Your "problems" are often artifacts of your OWN bad

I'm not sure that any noun would make sense in the context provided.
Static member-functions/variables are no different in kind from normal
functions/variables, only their scope may be different (if they are made
private or protected.)

Domain Driven Design and SaveAll()

2008-09-03T00:42:35Z

In our domain driven design, we allow clients to consume a service
that includes a "Save Step" method (public Step SaveStep(Step
userStep). This works great for the consumers of the web service
(easy call, just send back entire step object) and for persisting the
step data to the data store (just send the step to the repos).

Searching for a term / notion / concept

2008-09-02T17:52:04Z

This question refers to languages like C++ and Java, where
both objects and classes might have fields and methods (in
C++: »functions«).
How is an entity called that can have fields and methods,
when I do not care whether it is a class or an object?
A noun is wanted that can be placed into the sentence:
