Serializability refers to the concept in database management systems where a schedule (sequence of transactions) is considered serializable if its outcome is equivalent to one that could have been obtained by executing all transactions serially, i.e., one after the other, without any overlapping in time. It does not specifically mean that data used during the execution of a transaction cannot be used by a second transaction until the first one is completed; rather, it focuses on ensuring that concurrent transactions yield results consistent with some order of serial execution.
