A method call on a proxy from the client side. Consider the garage example
from the tutorial. GarageImpl exposes the business logic to the client. It
provides method like addCar(), which is a business process in this example.
addCar() is called from the client. But this method inturn calls other methods
on other objects. All the methods are running inside the same transactional
context.

All ozone objects have an identity. This is part of the oozone object model.
This cannot be controlled by the programmer. Each object automatically gets
an unique object ID.
