Question and answer
Q: what are the relative advantages of centralized and distributed databases ?
A: Advantages of Distributed Systems over Centralized ones 1:Incremental growth:Computing power can be added in small increments 2:Reliability:If one machine crashes, [ the system as a whole can still survive 3:Speed: A distributed system may have more total computing power than a mainframe 4:Open system: This is the most important point and themost characteristic point of a distributed
system. Since it is an open system it is always ready to communicate with other systems. an open system that scales has an advantage over a perfectly closed and self-contained system. Economic:ANd Microprocessors offer a better price/performance than mainframes Disadvantages of Distributed Systems over Centralized ones 1:As i previously told you distributed systems will have an inherent security issue. 2:Networking:If the network gets saturated then problems with transmission will surface. 3:Software:There is currently very little less software support for Distributed system. 4:Troubleshooting:Troubleshooting and diagnosing problems in a distributed system can also become more difficult, because the analysis may require connecting to remote nodes or inspecting communication between nodes.
