The Importance Of UML In Object Oriented Software Development Is Essay-worthy.

1. Discuss why it may be seen as an advantage to use business processes as a way to identify analysis classes and thus also the software classes in an object-oriented system. Identify and compare other ways of identifying software classes.

2. Examine the case for the waterfall life cycle.  Does the waterfall life cycle still play a useful role in modern systems development, and if so, at which stages?

Importance of UML to the success of OO software projects:

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.

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.

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.

Class diagrams

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.

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.

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.

 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.

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.

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.

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.
