Serialisierbarkeitsgraph
Präzedenzgraph
From the conversation with Adi Nagara@3rd example:
You have indeed no global cycle of all transactions. But you have a cycle in T1,T2. You could indeed say, that {T1, T2} (as one entity) and {T3} is conflict serializable.
Though, in this example I don't look at it in that way. My statement of "conflict serializable" / "not conflict serializable" refers to all transaction. So I mean "all transaction are conflict serializable" or "all transactions are not conflict serializable".
If you're concerned about exams, you should ask your teacher in which way he wants the statement to be.
Danke@123Chanel1994, WindowsSchmindows fuer den deutschen Namen.
