transaction databases

I am taking a database exam in three weeks and would like some help.

I am a liitle confused with transaction databases.

What is Conflict serializability?

I know a serial schedule is a schedule that carries out transaction one adter the other and a conflict may happen if two transaction access the same data item and one is a read operation, I think conflict serializability is that schedule shown in a serial but I'm not sure


What is View serializable?

I now that Schedule is view serializable if it is view equivalent to a serial schedule. But not much else about view serializability

Is a schedule that is view serializable also conflict serializable?

Any help would be much appreciated.

Thanks
