To lock any other vertex the transaction must have visited, Ask an Expert

Engineering

Consider the following graph based locking protocol, which allow only exclusive lock modes and which operate on datagraph that are in the form of a rooted directed acyclic graph.
- A transaction can lock any vertex point.
- To lock any other vertex, the transaction must have visited all the parents of that vertex and must be having a lock on one of the parents of the vertex. Show that the protocol ensures serializability and deadlock freedom.
