4.  WHAT IS UML?
• UML stands for “Unified Modelling Language”. It is
a modern approach to modelling and documenting
software.
• UML is being used as a “General-Purpose
Modelling language” in the field of software
engineering.
• It is based on “diagrammatic representations of
software components”.
• UML is a very important part of developing object
oriented software and the software development
process.
• UML uses mostly graphical notations to express
the design of software projects.

6. ACTIVITY DIAGRAMS
• UML Activity diagrams helps to describe the
activities involved in a process or in data
processing. It is object-oriented equivalent
of flow charts and data-flow diagrams
(DFDs).

8. USE CASES DIAGRAM
UML Use cases diagrams describes the
interaction between a system and its environment.
 A UML Diagrams contain the following components:
• Use cases . A use case describes a sequence of
actions that provide something of measurable value to
an actor and is drawn as a horizontal ellipse.
• Actors . An actor is a person, organization, or external
system that plays a role in one or more interactions with
your system. Actors are drawn as stick figures.
• Associations. Associations between actors and use
cases are indicated by solid lines. An association exists
whenever an actor is involved with an interaction
described by a use case.

13. CLASS DIAGRAM
• UML class diagrams are used when
developing an object-oriented system to
show the object classes in the system
and association between these classes.

16. STATE DIAGRAM
• UML State diagrams can show how the
system reacts to internal and external
events.

19. SEQUENCE DIAGRAM
• UML Sequence diagrams described the
interaction between actors and the system
and also between system components on
a time sequence. It shows how the
objects interact with others in a particular
scenario of a use case.

21.  USE OF UML DIAGRAMS:
Mainly, UML has been used as a general-purpose
modelling language in the field of software engineering.
However, it has now found its way into the documentation
of several business processes or workflows. For example,
activity diagrams, a type of UML diagram, can be used as a
replacement for flowcharts. They provide both a more
standardized way of modelling workflows as well as a wider
range of features to improve readability and efficacy.
UML itself finds different uses in software development and
business process documentation:
