A homogenous distributed database is which of the following?

  • A.The same DBMS is used at each location and data are not distributed across all nodes.
  • B.The same DBMS is used at each location and data are distributed across all nodes.
  • C.A different DBMS is used at each location and data are not distributed across all nodes.
  • D.A different DBMS is used at each location and data are distributed across all nodes.

Answer: B

Correct answer: The same DBMS is used at each location and data are distributed across all nodes.

Homogeneous means one product throughout, which removes the translation problems of a heterogeneous system: the same dialect, the same data types, the same transaction semantics. It is the easier case to build and administer, and it is realistic only where the organisation controls every site.
