A Transaction Wait-For Graph (TWF) is a directed graph used in database systems to represent the wait-for relationships among transactions. In this graph, each node represents a transaction, and a directed edge from transaction A to transaction B indicates that transaction A is waiting for a resource held by transaction B. By analyzing the TWF, database systems can detect deadlocks; if there is a cycle in the graph, it indicates that a deadlock has occurred, prompting the system to take corrective action. This method is crucial for maintaining concurrency and ensuring efficient transaction management.
