    A(n) ________ database stores each database fragment at a single site.

    • A.

      Partially replicated

    • B.

      Unreplicated

    • C.

      Fully replicated

    • D.

      Partitioned

    Correct Answer
    B. Unreplicated
    Explanation
    An unreplicated database stores each database fragment at a single site, meaning that there is no duplication or replication of the data across multiple sites. This can be useful in certain scenarios where data consistency is not a critical requirement, or where the cost of replicating the data outweighs the benefits. However, it also means that if the site where the data is stored goes down or becomes unavailable, the data will not be accessible until the site is restored.
