What is the difference between "conflict serializable" and "conflict equivalent"?


In database theory, what is the difference between "conflict serializable" and "conflict equivalent"?

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.


Solution

  • Just two terms to describe one thing in different ways.

    Conflict equivalent: you need to say Schedule A is conflict equivalent to Schedule B. it must involve two schedules

    Conflict serializable: Still use Schedule A and B. we can say Schedule A is conflict serializable. Schedule B is conflict serializable.

    We didn't say Schedule A/B is conflict equivalent

    We didn't say Schedule A is conflict serializable to Schedule B
