UML (Unified Modeling Language) is a universal modeling language in the field of software engineering. It is designed to provide a standard way to visualize the design of a system allowing the programmer to visually see what is required for the software he/she is working on. Many people believe that UML is not important to learn. That it is simply just a time consuming task, and in some cases that is true. But while UML can be time consuming, it can help multiple people understand the essence of a program that is being created. It allows everyone to be on the same page of what the end goal is and of the means to reach the end.

There are two types of UML Diagrams. There are Structural Diagrams, and Behavioral Diagrams. Structural Diagrams consist of diagrams such as Class Diagrams, Component Diagrams, and Deployment Diagrams. Behavioral Diagrams consist of diagrams such as Activity Diagrams, Communication Diagrams and Timing Diagrams. Structural Diagrams show what the software is made up of, while Behavioral Diagrams show what the software is doing step by step.

Above is an example of a Class Diagram. It consists of three sections. The upper section contains the Name of the class, it is necessary whether talking about a classifier or an object. The middle section contains the Attributes of the class. Attributes describe the variables of the class. This will tell what data type they are and whether they are public or private variables.

This (↑) is an example of a Component Diagram. It shows the components working together to create a system. The diagram names the objects tells the order, and shows the steps to reach the next component. This diagram in particular shows the water cycle. It shows that it is constantly goi...

...him/her to know exactly what is supposed to happen step by step. It allows for a much easier thought process.
Another type of Behavioral diagram along with Activity Diagrams would be a Sequence Diagram. Sequence Diagrams focus on the interactions going on in the system. They show how objects communicate with other objects to perform a function.
This diagram shows the system of making a new event on a calendar and announcing it. This is generally what happens any time you use something like google calendar to schedule something or other. First the form is requested and displayed, it is then filled out and the date is checked to make sure it is valid. If the date is valid then the occurrence is put on your schedule and an email alert will be made. This type of diagram helps the reader to understand what object is working with what other object and how it is doing so.

Essay on Use of the Unified Modeling Language (UML) for Design

- Unified Modeling Language (UML) is a graphical language used many types of systems models which shows different views of a system being design. The UML is used to describe the conceptual view and process view of an automated ticket-issuing system to be used by passengers on a railway station and for a computer-controlled video-conferencing system used with video, audio, and computer data to participants. Diagrams will show the conceptual and process view of these two systems and have justification for each of the decisions in the design....   [tags: Unified Modeling Language]

Unified Modeling Language Designs in Software Systems Essay

- As systems have become increasingly more complex, the need for communicating software systems has become a challenge. In response to that need, the Unified Modeling Language “UML” was developed and serves as a graphical language to describe those complex systems. UML is presently an industry standard representing a software system’s structure, interactions and behaviors in terms of graphical diagrams. UML has many types of diagrams each representing a different view of the system. In object-oriented programming, classes are used to separate and encapsulate business objects and behaviors....   [tags: computer programming]

UML and its fit in the business community Essay

- UML in the Business Community In the modern world, business analysts use UML as a communication tool to relay business needs to the IT professionals. What is the Unified Modeling Language (UML). Here is a definition of UML according to the Object Management Group (OMG) specification. “The Unified Modeling Language is a graphical language for visualizing, specifying, constructing, and documenting the artifacts of a software-intensive system. The UML offers a standard way to write systems blueprints, including conceptual things such as programming language statements, database schemas, and reusable software components.” First I will start out with a brief discussion on the history of UML....   [tags: essays research papers]

- Introduction This paper has the intention to explain what Rational Unified Process (RUP) is like an IBM product and a CASE tool. After is explained what phases it has, what are the most common extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a software design method created by the Rational Software Corporation and now is part of IBM developer software. This paper describes how to deploy software effectively. The Rational Unified Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence particularly applicable to larger software development teams working on large projects....   [tags: essays research papers]

A Study On Object Oriented Programming Essay

- As a result of these problems, to achieve high levels of reuse in OOP, one is often forced to write very small classes, which leads to an explosion in the number of classes in a system. (Krubner 2014, 41) The irony of all of this is that programmers reuse code without OOP—often by simply copying and pasting. There 's no need to superimpose some elaborate structure of interacting, instantiated objects, with all the messaging and fragility that it introduces into a program. (Mansfield 2005, 1) 7. OOP IS MORE DIFFICULT TO LEARN OOP requires more discipline, management and training than classic software development does....   [tags: Object-oriented programming, Programming language]

Essay on Is Object Oriented Programming?

- What is object-orientated programming. Object-orientated programming is methodology which is organized around objects and not actions. The perspective that this approach takes is that it is easier to compare objects. Object-orientated programming can be used in conjunction with UML, and within Object-orientated programming and there are various different methods. Object-orientated programming can be defined as constructing a model of a real world through combining data and actions. History of Object-orientated programming Object orientated programming first began in the 1960’s....   [tags: Object-oriented programming, Programming language]

- In this paper I will be discussing the differences and similarities of the three database models we have talked about in class the Entity-Relationship, Object model, and the UML modeling. First let’s look at the definition of the three models. The Entity- Relationship Model is used to visually represent data objects and is used for database design. It is easy to understand which makes it easier to communicate the design to the end user. The form used in the ER model can easily be transformed into relational tables....   [tags: essays research papers]
