ANS = the specialized use case takes all the base case scenarios; Text-based use case description should be used to provide additional information about use case definition; description should include the following: – Precondition = conditions that must be true for use case to begin, – Postcondition = condition that must be true once use case completed, – Primary flow = the nominal flow scenarios, – Alternate / Exception flows = scenarios that are less likely to happen / off nominal. Note, business actor is not defined in UML standard. In use case diagrams there are external actors (which may be users or processes that interact with your system). Use case diagrams model the functionality of a system using actors and use cases. Actors. A use case diagram at its simplest is a representation of a user's interaction with the system that shows the relationship between the user and the different use cases in which the user is involved. The use of a secondary actor easily communicates via the use case diagram through the use case details that the associated use case runs on a periodic basis. The associations between actors and use cases represent the communications that occur between the actors and the subjects to accomplish the functionalities associated with the use cases. --You can edit this template and create your own diagram.Creately diagrams can be exported and added to Word, PPT (powerpoint), Excel, Visio or any other document.

Actors can also display generalizations – have a subtype that inherits the structural and behavioral features of its supertype (using triangular arrowhead). In Visual Paradigm, you can make use of the sub-diagram feature to describe the interaction between user and system within a use case by creating a sub-sequence diagram under a use case. A use case diagram can identify the different types of users of a system and the different use cases and will often be accompanied by other types of diagrams as well. The Document Management System (DMS) use case diagram example below shows the actors and use cases of the system. Use case diagrams specify the events of a system and their flows. For example, for modeling a banking application, a customer entity represents an actor in the application. Extending use case = any use case that is the source – or element at tail end = of an extend relationship. Probably not . Development with UML 2, Provide an overview of all or part of the usage requirements for a system or use case diagram The extend use case may or may not run so its actually independent of the other use case. Define each candidate actor by naming it and writing a brief description. UML diagram that specifies sequences/ steps of operations to be performed A. Examples of some components of a student enrollment example are shown in the use case diagrams in the figure below.

Identify what are the users required the system to be performed to achieve these goals. A use case diagram consists of the system, the related use cases and actors and relates these to each other to visualize: what is being described? Eliminate actor candidates who do not have any goals. A use case diagram consists of the system, the related use cases and actors and relates these to each other to… Probably not . [5] If one actor specializes another, what does that imply?
