I'm not sure if someone will answer this question but i will ask anyway.
Basically i am trying to understand precedence graphs in terms of serializability.
Lets say for example i have the following transaction schedules:-
Whats the best way to work out how the nodes will be presented? I dont know how to link which nodes to what?read(T1, balx), write(T1, balx), read(T2, balx), write(T2, balx), read(T3, balx), commit(T1), commit(T2), commit(T3)
Can someone help?
