a. For every transaction Ti participating in schedule S, make a node labeled Ti in the precedence graph.
b. For every case in S where Tj executes a read_item(X) after Ti executes a write_item(X), create an edge (Ti→Tj) in the precedence graph.
c. For every case in S where Tj executes a write_item(X) after Ti executes a read_item(X), create an edge (Ti→Tj) in the precedence graph.
d. For every case in S where Tj executes a write_item(X) after Ti executes a write_item(X), create an edge (Ti→Tj) in the precedence graph.
e. The schedule S is serializable if and only if the precedence graph has no cycles.
