This paper advocates the idea that the physical modularity (file
structure) of application components supported by conventional
OS environments can be elevated to the level of logical modularity,
which in turn can directly support application development in an
object-oriented manner. We demonstrate this idea through a system-wide
server that manages the manipulation of such components effctively.
The server is designed to be a fundamental operating system service
responsible for binding and mapping component instances into client
address spaces. We show how this model solves some longstanding problems
with the management of application components in existing application
development environments. We demonstrate that this model's effectiveness
derives from its support for the cornerstones of OO programming:
classes and their instances, encapsulation, and several forms of inheritance.
