A new approach to operating system design is emerging in which, rather than attempting to hide these dilemmas, they are exposed to clients, using a meta-protocols. Object-oriented programming techniques play an important role in enabling meta-protocols to expose these dilemmas to the client in a...
•Enterprise OS. Future enterprises or organizations might need an OS to support the efficient management of processes as well as resources including people, funds, and machines. Enterprise OSs could be created out of existing enterprise systems, such as management information systems (MIS) or ente...

In this paper, we describe a new approach for operating system design that allows a more flexible composition of modules without increasing the complexity of the system. Our suggested solution is the application of the subject-oriented programming (IBM, SOP web page http://www.research.ibm.com/...

Operating systems also offer an interesting case study of system design. They are evolving rapidly because of new requirements. Their designers face a continuous struggle to control their complexity. Some modern operating systems have interfaces consisting of thousands of procedures, and their implementati...
