Self doubt - Serializability - DBMS
Can a schedule be serializable if it is not view serializable? Are conflict equivalence and view equivalence the only two ways to decide if a schedule is serializable?

View Serializability
Consider the following schedules: Which of the following is correct about above schedule? Only view serializable Only conflict serializable Both conflict and view serializable Neither view serializable nor conflict serializable. Please tell me the approach for checking view serializability ?

Are aborted transactions ALWAYS ignored when determining result/view/conflict serializability?
I am looking for some clarity on this topic. Here is some random schedule as an example: $r1(x) w1(x) r2(x) w2(x) r3(y) r3(x) w3(x) c3 a1 c2$ I was told, that for ... , strictness or avoidance of cascading rollbacks. I would be grateful if the question would be answered since this really confuses me.
