The difference between distributed and centralised databases:
Comparison between Centralised and Distributed
Databases
Centralised Database
- Centralised systems are easy to maintain as there is only a single point of failure.
- Centralised can be highly unstable.
- Low scalability
- Centralized systems can be created really fast; one picks up a framework and applies it everywhere.
- Since centralized systems follow a single framework, they don't have diversity and evolve slowly
Distributed
Database
- Distributed systems are the most difficult to maintain.
- Distributed systems are ye stable and a single failure doesn't do much harm.
- Infinite scalability
- For distributed, one has to first work out the lower level details like resource sharing (trade) and communications (transport).
- But for Distributed systems, once the basic infrastructure is in place, evolution is tremendous.
