UML Use Case Diagram Example. Registration System

UML Use Case Diagram
The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development. This diagram consists of actors, use cases and relationships between them. When constructing a diagram, common notation elements can also be used: notes and extension mechanisms.

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the types of user’s interactions with the system and is used at the registration and working with the database system.
"A registered user is one who uses a program or a website and provides his/ her credentials, effectively proving his/ her identity. ...
Generally speaking, any person can become a registered user by providing some credentials, usually in the form of a username (or email) and password. After that, one can access information and privileges unavailable to non-registered users, usually referred to simply as guests. The action of providing the proper credentials for a website is called logging in, or signing in." [Registered user. Wikipedia]
The UML activity diagram example "User registration" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.

This example was drawn on the base of SysML activity diagram on the page 8 of "SysML Modelling Language explained" document from the Official OMG SysML site.
"The activity diagram represents steps of a process, often making use of “input and output pins” that respectively correspond to the element type required as the input of an activity or action, and the element generated as an output.
If an action or activity corresponds to a block operation, it is possible to ensure that the types of the input and output of this activity are consistent with the block operation signature.
All the activity diagrams definitions used in UML also apply to SysML.
SysML has added a couple of extensions:
- With UML, control can only enable actions to start. SysML extends control to support disabling of actions that are already executing.
- Definition of the flow rate : continuous or discrete
- Definition of the rate and probability on the control or object flows"
