Web Engineering Lecture 12: Use Case Diagram in UML | Interactional Model | Web Engineering

Mehboob Hussain In today's lecture, we will discuss the interaction models. Basically, we will discuss the dip diagram. So, as we studied in prevention research, we have an interaction model. How the user interacts with the exercise, we will describe the different backgrounds in it. So, we can discuss the grammar used in it. It depends on the association. The association can

subscribe to any system. How does the use of any web system or android association work? So, how do you do different things with the system? What can be the reactors? Basically, the activity is that you have the user. The actor can be a mind and the actor can be a system. So, we will discuss the functionalities

of the system in the tag frame of basic reviews and all the activities that the actor has to perform there. The relationship with that system is whatever the screen is. There is a relationship between the system and the actor, how the actor has to interact with that system, in this way the actor has to perform different functionalities of the system, so

how we use that relationship will depend on it, we can create a single use case diagram in any system and we can also create multiple use case diagrams in any system, basically a use case diagram is a system which provides you this important thing with one hand, so it has it, we can also call it a

Tuesday diagram, basically it is a dialogue between the user and the system, just like a dialogue, we also call it a dialogue, because for this the actor in your system is a mere person, he can also be a robot, I also told you that when any automatic system can also be there, then this is
