Data Access in Dynamic Distributed Systems. Basics, Concepts and Techniques of P2P Query Processing

The disadvantages of distributed systems are summarized in Fig. 1-3. Despite these potential problems, many people feel that the advantages outweigh the disadvantages, and it is expected that distributed systems will become increasingly important in the coming years. In fact, it is likely that within a few years, most organizations will connect most of their computers into large distributed systems to provide better, cheaper, and more convenient service for the users. An isolated computer in a medium-sized or large business or other organization will probably not even exist in ten years.  Item Description Software Little software exists at present for distributed systems Networking The network can saturate or cause other problems Security Easy access also applies to secret data Fig. 1-3. Disadvantages of distributed systems. 1.3. HARDWARE CONCEPTS Even though all distributed systems consist of multiple CPUs, there are several different ways the hardware can be organized, especially in terms of how they are interconnected and how they communicate ...»
