Distributed Application Operating System Operating System Api

Middleware is a class of software technologies designed to help manage the complexity and heterogeneity inherent in distributed systems. It is defined as a layer of software above the operating system but below the application program that provides a common programming abstraction across a distributed system, as shown in Figure 1. In doing so, it provides a higher-level building block for progr...

Hospital Operating System

Introduction In the business management theory of constraints, throughput is the rate at which a system achieves its purpose. For a hospital the purpose or “aim of the system”, as W. Edward Deming refers to it, is to deliver quality patient care as efficiently as possible. Unfortunately, the fragmentation of a hospital’s activities across departmental operational silos propagates waste, comprom...

Operating System Transactions

Applications must be able to synchronize accesses to operating system resources in order to ensure correctness in the face of concurrency and system failures. System transactions allow the programmer to specify updates to heterogeneous system resources with the OS guaranteeing atomicity, consistency, isolation, and durability (ACID). System transactions efficiently and cleanly solve persistent ...
