Use Case diagrams are behavior diagrams of UML used to describe a set of actions (Use Cases) that some system or systems (Subject) should or can perform in collaboration with one or more external users of the system (Actors).
Each use case should provide some observable and valuable result to the actors or other stakeholders of the system.
Use case diagrams are a means for specifying:
the include relationship implies that the included use case must be enacted, whereas the extend relationship implies that the extending use case may be enacted.
Activity diagram shows the work flow from start point to the end point detailing many decision points. Sequence shows detail flow of specific use case and it also shows interaction between actors, system and system components
Class diagram is UML structure diagram which shows structure of the designed system at the level of classes and interfaces, shows their features, constraints and relationships - associations, generalizations, dependencies, etc.Communication diagram (called collaboration diagram in now obsolete UML 1.x) is an interaction diagram which shows interactions between objects and/or parts (represented as UML lifelines) using sequenced messages in a free-form arrangement.So, the major difference is that class diagram shows static structure of the system while communication (collaboration) diagram shows system behavior as sequenced exchange of messages between objects.
good
i want use case diagram for online banking system
potential difference
It is a hybrid between Use Case and Sequence Diagram
the include relationship implies that the included use case must be enacted, whereas the extend relationship implies that the extending use case may be enacted.
It's uml base model usely use of use case design and spiral model Risk driven approchs

I am trying to find out if this is the correct t-case for my 98 jimmy 4l60e/4.7 vortec
what is the difference between a server physical case and a client case
The four basic parts of a use case model are actor, use case, system boundary, and relationships between actors and use cases. Actors are users or systems interacting with the system, use cases represent user goals or tasks, the system boundary defines the scope of the system, and relationships show how actors interact with use cases.
Case length.
good
or not. ln case first string occlrs multiple times in second string, it reporis the number of times it occurs in second. Diflerentiate between dSrnamic loading and late binding.
