Quasi serializability is a new correctness criterion for concurrency control in multidatabase systems (MDBSs). A global execution is quasi serializable if its local executions are serializable and it is equivalent to a quasi serial execution in which global transactions are executed sequentially. In this paper, we present an algorithm which ensures quasi serializabilit.y by controlling submissions of global transactions. The algorithm groups global transactions in such a way that transactions… CONTINUE READING
