We refer in this paper to the schedule correctness principle of conflict serializability, but algorithms and methods exist also for the broader notion of view serializability (see =-=[5]-=- and the references therein). These criteria have been further extended to describe higher degrees of ...
View SerializabilityA schedule will view serializable if it is view equivalent to a serial schedule. If a schedule is conflict serializable, then it will be view serializable. The view serializable which does not conflict serializable contains blind writes. View EquivalentTwo schedules S1 and S2 are...
這稱為序列化能力 (Serializability),因為這樣可以產生重新載入起始資料並重新執行一系列的交易,以便讓資料最終能夠與原始交易執行後的狀態相同的能力。耐久性 完全持久交易完成之後,其作用便永遠存在於系統之中。 即使發生系統失敗仍會保存修改。 SQL Server...

Scalable TM implementations will be speculative, executing transactions concurrently where possible and transparently suppressing those that conflict, while guaranteeing that the history of committed transactions is serializable. Recently, practical language integration issues, e.g., publication and privatization...
