    If, however, data is lost in a distributed system, retrieving it would be very easy, because there is always a copy of the data in a different location of the database. Designing a centralized database is generally much less complex than designing a distributed database, as distributed database systems are based on a hierarchical structure.

  3. Distributed database - Wikipedia

    en.wikipedia.org/wiki/Distributed_database

    A distributed database is a database in which data is stored across different physical locations. [1] It may be stored in multiple computers located in the same physical location (e.g. a data centre); or maybe dispersed over a network of interconnected computers.

[ 2 ] [ 3 ] In general, a distributed ledger requires a peer-to-peer (P2P) computer network and consensus algorithms so that the ledger is reliably replicated across ...

  6. Distributed computing - Wikipedia

    en.wikipedia.org/wiki/Distributed_computing

    Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. [1] [2] The components of a distributed system communicate and coordinate their actions by passing messages to one another in order to achieve a ...

  9. Distributed data store - Wikipedia

    en.wikipedia.org/wiki/Distributed_data_store

    A distributed data store is a computer network where information is stored on more than one node, often in a replicated fashion. [1] It is usually specifically used to refer to either a distributed database where users store information on a number of nodes , or a computer network in which users store information on a number of peer network nodes .
