What is FSM in database?
Finite-state machine (FSM) is a wonderful model of computation that has many practical applications. One of my favorites is turning business logic into simple FSMs. For example consider the following requirements for an order management system: Orders must not ship before they are paid.
Should you use state machines?
State machines are useful if you can define a clear number of states and events that will trigger transitions to them. They might be good for user interfaces or communications protocols. However, when building complex systems, implementation of state machines is not the best option.
What’s the difference between a state machine and an activity?
State machine workflows provide a modeling style with which you can model your workflow in an event-driven manner. A StateMachine activity contains the states and transitions that make up the logic of the state machine, and can be used anywhere an activity can be used.
What do you need to know about state machine workflow?
State machine workflows provide a modeling style with which you can model your workflow in an event-driven manner. A StateMachine activity contains the states and transitions that make up the logic of the state machine, and can be used anywhere an activity can be used. There are several classes in the state machine runtime:
How to create a finite state machine in SQL?
UPDATE dbo.ItemState SET stateID = tr.nextStateID FROM #temp t JOIN dbo.ItemMachineState ist ON ist.itemID = t.itemID JOIN Transition tr ON tr.stateID = ist.stateID AND tr.machineID = ist.machineID AND tr.eventID = t.eventID
Where are breakpoints located in state machine workflow?
After the exit action completes, the activities in the transition’s action execute, and then the new state is transitioned to, and its entry actions are scheduled. When debugging a state machine workflow, breakpoints can be placed on the root state machine activity and states within the state machine workflow.
