Replica and concurrency control


In a replicated database, there exist several database servers each of them maintaining a (partial) copy of the database. Thus, each logical data item of the database has several physical copies or replicas. As transactions submit their read and write operations on the logical data items, the replica control component of the replicated system translates them into operations on the physical data copies. The concurrency control componentof the replicated system controls the execution order of these operations such that the global execution obeys the desired correctness criteria. For a tightly coupled system with strong consistency requirements, 1-copy-serializability is the standard correctness criterion, requiring that the concurrent execution of transactions on the replicated data has to be equivalent to the serial execution of these transactions over a logical copy of the database. Thus, a global concurrency control strategy is...
