Discussion
A distributed database is which of the following?
Answer: A
Correct answer: A single logical database that is spread to multiple locations and is interconnected by a network
Two conditions must both hold. It must be a single logical database, so users see one coherent whole rather than several separate ones; and the sites must be connected by a network, or nothing can be combined. Separate databases on separate machines are a decentralised system, not a distributed database.
