1UML DIAGRAMS AND MODELLING REPORT
Use Case Diagram:
The use case diagram is the mixture of use cases of a given system. The use case
depicts the single function of a system. The use case diagram help the user to understand the

Activity Diagrams:
The activity diagram is the combination of activities of the given system. An activity
is defined as the function that is performed by the system. The activity diagram is used to
depict the flow control of the system. Activity Diagram is another imperative outline in UML
to portray the dynamic parts of the framework. The control stream is attracted starting with
one activity then onto the next. Activity diagram mainly contains flowchart of the activities
that are performed by the system. The activities in the system is itself the main part of the

activity diagram. It is not only used to depict the visual part but also to construct the
executable application. The basic use of the activity diagram is to draw the flow of control in
the system. This project need three-activity diagram because there are various parts and flow
of system.
