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.

Algorithm that checks whether the concurrently executing transactions are in deadlock?
A common algorithm to check for deadlocks in concurrently executing transactions is the Wait-For Graph (WFG) approach. In this method, a directed graph is constructed where each transaction is a node, and a directed edge from transaction A to transaction B indicates that A is waiting for a resource held by B. The system checks for cycles in this graph; if a cycle is detected, it signifies a deadlock among the involved transactions. Periodically analyzing the WFG allows the system to identify and resolve deadlocks efficiently.
