[@srinivasraonammi7280]

sir the videos is very good. i have a question regarding the actors why because u said that we have primary actor and secodary actor. where secondary actor is the person who interacts after primary actor has made an initiation. but here in the example both actors are named as customer. my doubt is primary actor used all the 4 use cases but why again we have on right the same actor using the same use cases twice. i mean actors representation is done twice(right and left)

[@ab-eq4hu]

sir, please clear my confusion about login and registration usecases. Can we also draw registration as the extended usecase of login? or it will be wrong to do so?

[@Master2Teach]

Thank you so much for watching the video and question. Login and Registration are separate use cases. Whenever the base use case is called by the actor, and extended use case may or may not call. If it calls, then it will call from the base use case internally. In the above case. if login fails, it displays an error, it will not call the registration use case. So login extends the error message. Ya, we can show in extension point as option or link but I suggest, best to show these two use cases separately. And these two use cases have their own extend and include use cases as well. Hope you are clear about it now. Don't forget to like, share, and subscribe the channel.

[@ab-eq4hu]

@@Master2Teach Thank you so much sir for such a good explanation. You mean we will draw both the use cases separately. i have one more question which will clear me all the things. Can we generalize the user as new user and registered user and then connect the login usecase with the registered user and Registration usecase with the new user. And all other usecases which are common will be connected with the parent user? As, i have a project of online food ordering system, so can you please explain me this in the context of my project? I will be really thankful Sir.

What will be the auto functionality mentioned in ysecase as? Can. U te" me

[@randomshorts2681]

Why secondary actor is also performing functions of primary actor? Why functions of secondary actor are not different from primary actor?

[@natsudragneel2027]

The functions of the secondary actor can be same or different. For example, if primary actor tries to register (in order to get the course), now secondary actor may want to approve the registration manually . So in order to approve the registration manually the secondary actor will have to access the registration function. So by accessing the registration function secondary actor can get detail and according to that the secondary actor can reject of accept. If the secondary actor wants to perform a function which primary actor can never perform, in this case the different function has to be created.

automatic system is in left side or right side ?

[@Master2Teach]

Thanks for good question. In use case diagram, primary actors are place in left side whereas secondary are in right side usually. In case of system as an actor which perform certain automatic job can be place on right side but note that there is not hard and fast rules.

how is enrollment a class please explain

[@Master2Teach]

Thank you for your question. If student enroll in course then there is association between the student and course class. To support these two classes interaction and further information, Enrollment class will help which is known as Association Class. It hangs with dotted line without arrow head in between student and course class. I hope this will help you to understand the association class.

Hello again, I am just beginning to learn system design and coming across your videos is like coming across an ACE. Could you tell me how to get started with this idea, it's for my school. I want to simulate a RENTAL SYSTEM. To rent educational Equipment to Teachers and Palestrants. I want to create a system to control who takes de device, when, time, in stock or not and threturn of this equipment. It will look like renting a DVD or a book and returning it. I don't know if you are able to understand my system. lol thanks

[@Master2Teach]

[@hibahasan9627]

good content but your example at the end is useless because i didn't benefit from it. in my opinion you must first show the textual description of the project and then based on the description you draw the use case diagram. this way we can know how to think when want to draw a use case diagram.

[@alijaved848]

you forgot to name the actors?

[@NidaZainab-j4v]

[@gathorn]

Why does "Book Courses" or "Make Payment" not include "Login"? i can't book a course without logging in. Thank you for the video btw.

[@aminurrahmanashik2786]

This is really depends on user or client's choice how he/she wants the system to be, but in common this video represents only for a particular use case, not overall, I guess. That's why 'register', 'make payment' or others have not been described clearly.

[@Master2Teach]

The relationship in use case diagram that is include and extend are the use cases which are called automatically from the base use case. For example, Login and verify login details, here, login in base use case whereas verify login details is included use case. Whenever user call the login use case, it automatically call the verify login details use case. So for the relationship in use case diagram, we specify or draw include and extend relationship to those use cases which are call automatically from the base use case. As your concern, book courses and make payment and login are all base use cases and login do not call book courses or make payment automatically. So that there is not relationship between them. So need to remember that, use case diagram is system diagram which show the system from the user point of view. It's not the flow diagram. I hope it make you clear. If you have still confusion, pls text me at [e-mail]. Thank You

[@Walruz1000]

In your example diagram what would the use case description be for it? It seems to encompass logging in, registering, booking and making a payment so whilst the diagram makes sense I am a bit confused about what exactly the use case description is because it looks like it could many things.

[@Walruz1000]

One more thing, when sneezing you use includes, but surely this is not correct because closing your eyes is something you would do without just sneezing, for example going to sleep, thinking, or just simply "closing your eyes". So is this saying that an included use case can also be actor initiated?

[@Master2Teach]

Thanks for good question. Actually the example of closing eyes here is different use case than the other closing eyes. The closing eyes use case while sneezing is called internally from sneezing. So this closing eyes use case while sneezing can't be initiaed directly from actors.

[@Walruz1000]

@@Master2Teach so would you usually have 2 separate use cases for the same thing if say on a human we could close eyes sneezing or close eyes in general?

[@NavidIsANoob]

@@Walruz1000 Not sure if it's still relevant for you, but what you use as base use cases all depends on what the client wants. Remember, you have to make a diagram that describes the system usage from the client's perspective. So if sneezing is a use case of your system, closing your eyes will be included in that use case. (As an included use case). If closing your eyes is ANOTHER base use case for your system, then you have to make a separate use case for that function. In this example, "closing your eyes" as an include for sneezing is NOT THE SAME as "closing your eyes" as a base use case in the system. They are two separate use cases.
