Consider A Bank That Has A Collection Of Sites, Each Running A Database System. Suppose The Only Way The Databases Interact Is By Electronic Transfer Of Money Between One Another. Would Such A System Qualify As A Distributed Database? Why? |

Answer» In a distributed system, all the SITES TYPICALLY run the same database management software, and they share a global schema. Each site provides an ENVIRONMENT for EXECUTION of both global transactions INITIATED at remote sites and local transactions. The system described in the question does not have these properties, and hence it cannot qualify as a distributed database.
