Prove that all regions of the diagram are non-empty sets by providing example histories H1-H12
answer should be similar to the below
T1= w1[x] w1[y] w1[z] c1
T2= r2[u] w2[x] r2[y] w2[y] c2
And also consider the following four histories over transactions T1 and T2:
H7= w1[x] w1[y] r2[u] w2[x] r2[y] w2[y] c2 w1[z] c1
H8= w1[x] w1[y] r2[u] w2[x] r2[y] w2[y] w1[z] c1 c2
H9= w1[x] w1[y] r2[u] w2[x] w1[z] c1 r2[y] w2[y] c2
H10= w1[x] w1[y] r2[u] w1[z] c1 w2[x] r2[y] w2[y] c2
H7 is not Recoverable (RC).
H8 is Recoverable (RC) but not Avoids Cascading Aborts (ACA).
H9 is Avoids Cascading Aborts (ACA) but not Strict (ST).
H10 is Strict (ST).
