冲突可串行化“之间的区别是什么和“冲突等价物”? [英] What is the difference between "conflict serializable" and "conflict equivalent"?
问题描述
在数据库理论中,冲突可串行化和冲突等价物之间有什么区别?
In database theory, what is the difference between "conflict serializable" and "conflict equivalent"?
我的教科书有一个关于冲突序列化的部分,但是掩盖了冲突等价性。这些都可能是我熟悉的概念,但我不熟悉术语,所以我正在寻找一个解释。
My textbook has a section on conflict serializable but glosses over conflict equivalence. These are probably both concepts I am familiar with, but I am not familiar with the terminology, so I am looking for an explanation.
推荐答案
p>只需两个字词,以不同的方式描述一个事物。
Just two terms to describe one thing in different ways.
冲突等效:您需要说明Schedule A是冲突等同于Schedule B 。它必须包含两个计划
Conflict equivalent: you need to say Schedule A is conflict equivalent to Schedule B. it must involve two schedules
冲突可序列:仍然使用计划A和B.我们可以说计划A是冲突可序列化。计划B是可串行化的冲突。
Conflict serialible: Still use Schedule A and B. we can say Schedule A is conflict serializable. Schedule B is conflict serializable.
我们没有说A / B冲突是等同的。
We didn't say Schedule A/B is conflict equivalent
我们没有说A冲突可序列化到Schedule B
We didn't say Schedule A is conflict serializable to Schedule B
