The aim of UML’s implementation is to provide software developers , system architects, and software engineers with tools for analysis, design and implementation of software-based systems. We can find that there are a few types of UML including class, use case, object, collaboration, sequence, activity, component deployment and statechart. For class diagrams, it become the backbone of almost every object oriented method and describe the static structure of a system. Other than that, we using actors and use cases in uses case diagram to represent the system functionality. Object diagrams was function as describing the static structure of a system at a particular time. Then, in collaboration diagrams, they shows interaction between objects and describe both the static structure and the dynamic behaviour of a system. For sequence diagrams, it shows interaction among classes in term of an exchange of messages over time. For activity diagram, it give a view of dynamic of a system by modelling the flow of control from activity to activity. For component diagrams, it explain about the organization of physical software component (run-time code, executables, and source code). For deployment diagrams, it view the physical resources of a system, nodes, components, and connections. Last diagram is statechart diagrams. This diagram shows the dynamic behaviour of a system in response to external stimuli. It especially useful in modelling reactive object. Why we use the UML? Many people think that they can express an ideas in a quick way by picture. You can think a lot of ideas because UML is standard way to views of a piece of software including user view, source code, architecture, internal structure of software, and hardware.

Tabular Collection Diagram shows the process of the system, so it helps identify risks or problems in a system early on. Tabular Collection Diagram put requirements to the test and enables you to see if more requirements are desirable. A brilliant method to discover problem’s in the earlier stages of development.
Use Cases is the best technique to figure out the technical aspects of the system, it help you understand the functionality of the system and its interaction with the humans (Actors), the Use Case Diagram is best to present your requirements in terms of processes and it allows you sort out any errors before the implementation of ...

Software engineering is a relatively new career but the most important component of software engineering, the computer, has a long history that started many centuries ago. The abacus, a tool composed of beads and strings representing numbers, is considered by many to be the original computing device. The abacus, a device developed in Asia, was widely used during the Middle Ages. The abacus is still used today by many students. The next important milestone in the creation o...
Software applications are powerful tools in the battle to make businesses more efficient and effective. Many have tried to make do with commercial off-the-shelf software (COTS), only to find that their specific needs demanded professionally developed software. Others insist on reinventing the wheel by developing software in areas where vendors are offering an already mature, reliable and relatively cheap version to buy.
U.D.L stands for universally designed curriculum. The UDL is made up of 4 essential pillars. The end goal, materials and resources, methods, and assessments. All of these things are important and just like a house if one corner is built on a weak foundation it can all come crumbling down. Luckily however the U.D.L is tried and true and can be a valuable asset to help in the evaluation process.
Draw a UML class diagram for the Online Business and Payment system(WOBPS). The class diagram should represent all of the classes, their attributes , operations , relationships between the classes, multiplicity specifications, and other model elements that you find appropriate.
A documentation framework is essential for any large project; hence, RUP describes how to document functionality, constraints, design decisions and business requirements. Use Cases and Scenarios, are examples of artifacts prescribed by the process and have been found to be very effective at both capturing functional requirements and providing coherent threads throughout the development and deployment of the system.
In recent years a cognizance has grown of the importance of software architecture. ”The software architecture of a system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships among them”-- Bass et al [1]. Software architectures are essential because they represent the single concept for understanding the structure of a system and form the basis for a collective understanding of a system and all its benefactors. The IEEE recommendation outlines architecture as the fundamental organization of a system embodied in its modules, their relationships to each other and to the environment and the main beliefs guiding its design and evolution.
One of them being the Unified Modeling Language also known as UML. In the article "The impact of UML documentation on software maintenance: An experimental evaluation." it describes that often most software maintenance is performed usually by people who were not involved with the original design. It goes on to say that “…designs often has been advocated as a necessity to help software engineers remain in intellectual control while changing complex systems.” Compounded by the fact that documentation eats up a lot of time and money. This has led to a tremendous problem. This is where UML comes into play, this is an evolving standard that companies are beginning to adopt to help stop this issue. UML gives a way to visualize a software’s architectural patterns in various diagrams. Some examples of this include components of a system and how they interact with other components, how the system will run, and how entities will interact with others. All of these diagrams work together to aid in the process of writing the actual code and the maintenance of the code in the future. It also serves as well written documentation that is easy to read. To sum up the article UML provides a cost-effective way of creating documentation because of that it also aids in the design
The UMLS is a very detailed subject, and I have provided a brief overview. To adequately understand the complexity of the UMLS would require many pages of detailed explanations. Mainly, for our purposes we simply need to understand a broad overview to relate the importance of the UMLS to the HIM
There are various software models available for developing the software’s depending on the project requirements the models are used. Because it completely explains when the user should proceed to next phase and when to conduct tests. The below are the few different software models
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.
Way of Working – UP is use case driven methodology developing system iteratively and incrementally thereby adding flexibility to process. This flexibility allows us to quickly react and afford frequent changes during development process. (Satzinger & Others, 2005) (Daoudi & Nurcan) Each iteration is a small part of project needed to be developed under four phases – Inception, Elaboration, Construction and Transition. UP defines six disciplines in each phase to better manage iteration. These are - Business modeling, requirements, design, implementation, testing and deployment. (Satzinger & Others, 2005) Every iteration carry out different activities form all discipline and deliver an increment at the end of iteration. Each increment developed during iteration consists of added functionality as compared to previous increment. So, iteration itself is capable of accommodating any design or requirement modification. (Satzinger & Others, 2005) (ISQA 8220 Notes)...
