A distributed transaction management scheme for multidatabase systems

Transaction management in a multidatabase system must ensure global serializability. Local serializable execution is, by itself, not sufficient to ensure global serializability, since local serialization orders of subtransactions of global transactions must be the same in all systems. In this paper, a distributed transaction management scheme is introduced. The scheme maintains the autonomy of the local database systems. It is free from global deadlock and guarantees fairness in the execution of the transactions in the system.<
