Detailed Report on UML Diagrams: Types, Components, and Usage

This report provides a comprehensive overview of UML (Unified Modeling Language) diagrams, which are primarily used for visualizing software programs. It highlights various UML diagram types, including package, object, component, deployment, class, and composite structure diagrams, as well as behavioral UML diagrams like activity, sequence, use case, and state timing diagrams. The report elaborates on activity diagrams, also known as flow charts, which represent the flow between activities, and use case diagrams, which graphically represent system elements. It also discusses class diagrams, which group classes with common characteristics, and interaction diagrams, which describe system behavior through sequence and collaboration diagrams. Specific web page outputs such as home page, search functions for movies, customers, and games, and creation of new movies, customers, and orders are mentioned as practical applications.

UML Diagram:
UML is mainly used for visualizing the software program. The software program
contains the many number of diagram (van Sinderen, 2008). OMG is supported for the UML
diagram. UML is also known as Unified Modeling Language. UML is used to improve to
interact the models like diagrams.
The UML Contains the following diagram are given below:
Package, Object, Component and Deployment, Class, Composite
Structure.
The Behavioral UML Contains the following are given below:
Activity, Sequence, Use case, State Timing .This are the behavior of UML
diagram.
ACTIVITY DIAGRAM
Activity diagram is the type of UML diagram. Activity diagram also known as flow chart. They
are used to represent the flow of two activities (Bajgoric, 2005). Show the flow from one activity
to another activity. The system operation can be defined by this activity. One or more operations

are used, control flow are used to draw the operations. Flows are in different forms like
sequential, branched, or concurrent. Different types of elements are used such as fork, join, etc.
PURPOSE
1. Design the activity flow of a system.
2. Define the sequence between two or more activities.
3. Parallel flow of the system, branched and concurrent flow of the system are
designed.
USE CASE DIAGRAM
It’s a type of UML diagram. UML stands for Unified Modeling Language. Use case diagram are
used to represent the system elements in a graphical way (Rho and Vasilakos, 2017)

. In use case methodology no of operations are performed such as identify, clarify,
organize the system requirements. Basically use case diagram contain four different types of
components.
 Boundary- boundaries are used to define the system interest.
 Actors- each actor perform their operation initially.
 Use cases- they are played by the actors around the system.
 Relationship- establishing the relationship between the actors and use cases.
CLASS DIAGRAM
Class diagram contain types of groups. Each group include no of classes. They are used to share
the common characteristics. In class diagram, classes are represented by boxes. Each boxes are

divided into three rectangles (Niu, 2018) . The top rectangle contain name of the class and the
middle one is contain attributes of the class and final one is used to represent the methods,
methods are also known as operations.
INTERACTION DIAGRAM
Interaction diagram is used to describe the behavior of the system. And in the
interaction diagram it is separated by sequence diagram and collaboration diagram. The two
diagrams are more or less same. Sequence diagram is used to describe the time continuous of the
messages and a collaboration diagram describes the object structure in the way of sending and
receiving the messages. Interaction diagram is used to show how interaction is happened
between the systems. And it is used to describe the behavior of the system.
