2SYSTEM ANALYSIS AND DESIGN
Introduction:
The object oriented software projects or the OO software projects are typical software
models that are organized around the objects (Dennis, Wixom and Tegarden 2015). The
object oriented design process is the method of supporting the object oriented paradigm. The
main aim of using this process is dividing the object oriented projects into manageable
portions which are considered as the classes of programming. Like the classes, another
important aspect of object oriented software design is the unified modeling language. The
UML is used both for the non-software and the software system (Petre 2013) and for the non-
software systems the importance of the UML is the modeling of the OO software
applications.
In this magazine article, a short description of the unified modelling language will be
discussed. Following that, the main importance of the unified modeling language in the
development of object oriented software projects will be discussed in this article.
Importance of UML to the success of OO software projects:
The main aim of the unified modeling language is providing the standard type of
notations. This notation can be used by every method of the object oriented (Kalinowski et
al. 2014). Also, this notations can be used for integrating best precursor notation elements.
The design of the UML supports a wide range of applications. Thus it holds major
importance in the development of the wide range of activities and systems like the distributed
systems. The first noticeable thing is that the UML uses various different type of diagrams in
the object oriented software development project. The main reason behind using various
types of diagrams is that a system can be viewed from the different type of viewpoints.
The UML of the unified modeling language is a standardised type of modeling
language which consists of some specific set of diagrams (Rumbaugh, Booch and Jacobson

2017). This set can help the software and the system developers to documenting, visualising,
specifying and constructing the objects of a software system. The UML consists assembly of
best practices of engineering that are successful in the modeling process of the complex and a
large system. To express the design of the object oriented software projects, graphical
notations are used in most of the cases. In the context of the objected oriented software
projects, the unified modeling language helps the teams of the software development project
to communicate with each other. Also, with the communications, this UML helps to discover
potential object oriented software design and to validate the architectural design of the object
oriented software. The importance of the UML in the object oriented software development
process will be described briefly in the following section.
Class diagrams:
While considering the main importance of the unified modeling language in the object
oriented software development, the UML class diagrams are very much important in this
aspect. The UML offers a class modeling notations in the development process of the object
oriented software. This class diagram of the UML is considered as the bridge in between of
specification of the software at the side of the user and realization of the software at the side
of the developer (Mallick and Das 2013). It requires a strong set of guidelines for class object
identification from the domain of the problem. It also requires conventions of notation for the
class diagram modeling to use it further in the coding of the object oriented software. The
class diagram is very common in the object oriented system modeling. This is used for
modeling the static design view of an object oriented software. In the process of the
implementation of this class diagram of the UML plays another important role in the aspect
of the object oriented software development (Cabot, Clarisó and Riera 2014). In this case, the
class diagram can be used for the generation of the basic structure code of the object oriented
software.

Object diagram:
The unified modeling system also helps by providing the object diagrams in the
process of the object oriented software development. The object diagram is related to the
class diagram in this process. It is related with the class diagram in the way that it displays
the snapshots and the objective sets of the instances of the things that are found in the
diagrams of class in UML (Rumbaugh, Booch and Jacobson 2017). It actually helps to set the
architecture and distribute the classes into respective packages which are essential for the OO
software development.
Use Case diagram:
This diagram of the UML displays use case sets, actors and the relationship between
them. This is important in the aspect of modeling and organising the behaviour of the
software which is under development. As the actors have a relationship between them, use-
case can be invoked by them and also there are various types of relationships between the
use-cases (Mondal, Das and Banerjee 2014). The main usage of the use-case diagram is in
modeling requirement of the software.
Collaboration and Sequence diagram:
This is the interaction diagram of the UML. In this case, the interaction is shown
between the objects of the software. This also shows the relationship between the object with
the messages. This actually provides a dynamic view of the OO software. The sequence
diagram highlights the message time ordering (Thakur and Gupta 2014), and the
collaboration diagram highlights the structural organization of the objects which are in
interaction.

Statechart diagram:
The statechart diagrams are used for displaying the state machine which consists the states,
activities and the event of transition (Khan and Porres 2015). It also helps to acquire the
dynamic view of the object oriented software. In the case of the modeling behaviour, this
diagram is very much essential.
Activity diagram:
The activity diagram is also a state chart diagram but with some different properties.
The main role of the activity diagram is presenting the flow from an activity to another
activity within the object oriented software (Jena, Swain and Mohapatra 2014). In this way,
the activity diagram helps to find concurrent activities within the software which helps the
developers to develop the software in a much more easier way. Also, the graphical
representation of the activity diagram is useful when the complex processes are implemented
with concurrently running multiple things.
Component diagram:
The component diagram in the software development process is used for describing a
set of components. In the description process, it actually describes the dependencies and the
organization among component sets. This component diagram is also related to the class
diagrams. This component diagram is related with the class diagrams in the way of
component mapping to one class or more than one classes, collaborations and interfaces
(Rumbaugh, Booch and Jacobson 2017). The components diagram is very much important in
the object oriented software projects as it makes the tracking of dependencies easy in a
typical complex solution.

Deployment diagram:
The deployment diagram is used for explaining the run-time processing node
configuration and the components of it. Static deployment view of architecture is shown by
the deployment diagram.
Conclusion:
From the above discussion, it can be concluded that the unified modeling language is very
much important in the aspect of object oriented software projects in the present generation.
The unified modeling language or the UML provides the use case modeling to the approach
of object oriented software projects, and that is very much important for this type of project.
In this magazine article, the importance of the unified modeling system in the success of the
object oriented based software projects has been discussed briefly. This article assessed that
the UML has a total of nine important diagrams for the software projects and each of the
diagrams is equally important for successful object oriented software projects. These UML
diagrams provide different types of functionality to the object oriented software projects
which are very much essential. Further, how this different type of diagrams contributing in
the successful object oriented software projects are described briefly.
