So who would get the payment from the user, hand out the ticket, reimburse money in relation with the system ? If it's just the online booking system, we are fine.

But the method Update Seats makes obvious that we are talking of a real theater.

Here for example, I first thought it was an internet movie business. Identify obviously missing actors for important use case that you have identified. Some candidate actors might appear to be in fact only objects that are unrelated to users (it's not the case here, but it could be, for example, if you'd have a Movie producer, which is just an info related to a movie but not a user of the system). I let you as an execise sort out the rest.Īfter having identified meaningful use cases you may want to review your candidate actors:

Get registered and Confirm registration of visitor are obviously part of the same use case, because the goal is the same: registering a user.update movie catalog would be composed of update movie, Add movie record, Update movie record, delete movie record.You have then to find which are use cases and which are just interactions part of the same use case.

Implicit/inferred use cases or interactions : create and maintain admin, create a visitor, register and maintain a registered user account, anything else ?Īmong all the potential use cases and interaction identified, not all should get the use case status. Less explicit candidate use cases or interactions: View movie (relation and method of Registered user), update movie (relation), Add movie record (method of admin), Update movie record (method of admin), delete movie record (method of admin), Confirm registration of visitor (inferred from relation), 'Get registered (method of a user),cancel ticket (and method ofRegistered user ),Login (method ofRegistered user ),Logout (method ofRegistered user ),Update Seats available (method ofBook tickets), confirm transaction (method), refund money of cancelled ticket (method) Very explicit candidate use cases: Book tickets (class and method of Registered user), Make payment (class and method of Registered user) So let's brainstorm a little bit to find everything that looks like an interaction: The classes Movie, Book tickets, Make payment are obviously not representing roles of a user.Ī use case defines the interactions of a system and an actor in order to achieve some goal. Candidates in your diagram are: visitor, admin, and registered user However, by analyzing your specific diagram from a human point of view, you can very well infer a class diagram:Īn actor specifies a role played by a user or any other system that interacts with the subject. In fact, for a given class diagram, it's not even granted that there is a use case at all (for example, if the classes represent only the relation between business objects and no actors).

Check out all our UML diagramming resources for more help learning how to make these diagrams and when to use them.As Thomas pointed out, there is no algorithmic way to go from a class design to a use case. Use case diagrams are just one of many types of UML diagrams.
