Unified Modeling Language (UML)

Introduction Modeling means designing of software before coding. It is not easy to visualize software before developing it. Therefore, a visual model such as UML makes it simple to understand, by visualizing it from multiple dimensions. This paper discusses the various functions of UML, and why it was developed. It will conclude by discussing its impact on modeling.Advertising We will write a custom research paper sample on Unified Modeling Language (UML) specifically for you for only $16.05 $11/page Learn More Functions of UML UML is a third generation object oriented programming language created, and managed by the Object Management Group from 1997 (Erickson, 2008) It produces standard visual models for software applications and system architectures. UML was used to analyze future application requirements with solutions that met them, using customized diagrams. It shaped models that provided design solutions that were to be delivered by software system s (Deitel Deitel, 2008). To ensure that the system went through technical analysis process for satisfactory development, a model had to be formulated. Properly modeled systems helped in minimizing loss of information and misinterpretation in communicating the decisions taken during development. Team members developing a system would have a better understanding on how to go about the implementation process if an appropriate and, user definable model was created for that system. Why UML was developed Different companies initially defined their requirements in languages that were totally unfamiliar to software vendors hence the need to produce a unified language that would simplify modeling and make it understandable by all vendors. UML is a communication tool which gets key information of what the code should do. It is an architectural tool which makes obstacles to be seen from high levels. Software that are poorly documented or not documented at all can make a company lose command o f what the software operates, thus making modeling a vital tool in software development. UML was created to be used in modeling of software intensive systems by use of diagrammatic models making it easy to introduce more objects to an existing project. Its visual models provided the ability to convey large amounts of complex information in ways that were easy to understand (Mammar,   Laleau, 2006). Requirement gathering stage also required this kind of language where used case diagrams show users what to do as well as what the system needs to do for them. They were also suited as basis for testing applications and forming user guides.Advertising Looking for research paper on communications media? Let's see if we can help you!

Being object oriented, it led to web development which wasn’t previously on the minds of p rogrammers. Systems that were developed without modeling mostly deviated from their requirements. Increasing model coverage would help reduce incorrect implementation of systems. UML went further to reduce the defect density in software systems compared to those developed without modeling. The right decisions can now be made earlier in the development process and re-usable code identified therefore producing a system with the highest efficiency, and low development costs. Re-work in development lifecycle has been eliminated since that whole system can be viewed before implementation starts (Booch, Rumbaugh, Jacobson, 2005). New members can find it very easy to integrate into the development team through the visual assistance offered by the easy to understand UML diagrams. The efficient documentation of the system also makes it easy for internal and external stakeholders to share. In the case where incremental software development model is employed, UMLs allow the developer to first fulfill areas that are urgently required for the project to work while still developing other additional extensions hence maximizing reusability. Different parts of the same complex model can be independently implemented by different groups if the UML models are user-definable. Conclusion For system requirements to be easily understood by implementation groups, it’s important to employ UMLs since they simplify the system, and make reusability and maintainability simpler.

Sample Essay on Work Achievements

Sample Essay on Work AchievementsIf you are hired as a private attorney for the plaintiff in a lawsuit, and you have a need to write a sample essay on work accomplishments, this article will help you out. We will first look at how the word accomplishments is used in a regular work context. We will then look at how it is used in a lawsuit context.Accomplishments are normally used in reference to any thing that you do well or did not do so well. So, if you are an employee, you might be asked how much you are paid. You might be asked, 'How much do you make?' These are all instances where an attorney might use the word accomplishments.Now, we are going to focus on how the word accomplishments is used in a lawsuit context. This might seem like an odd place to look for achievements, but because of the adversarial environment that lawsuits can put you in, you want to focus on achievements that relate to your particular lawsuit. Here is where you might be asked, 'What was the most difficult aspect of your case?'Some examples of accomplishments that would fit these situations include but are not limited to, writing briefs, drafting pleadings, presenting legal arguments, researching cases, gathering evidence, and just about every other aspect of a case. Keep in mind that your accomplishments in a lawsuit should be those that related to your specific lawsuit.If you really want to get into the nitty gritty of writing a sample essay on work accomplishments, you might want to look at an attorney who has not yet had a case go to trial. These are usually less formal. You might be able to get away with a shorter sample essay on work accomplishments if you talk to a person that actually has some experience in this type of litigation. You can be able to help him or her write a well-written sample essay on work accomplishments.After writing the sample essay on work accomplishments, you will want to discuss it with the attorney. In addition to working on the sample essay on work ac complishments, you might want to focus on the number of your particular litigation. This could help you increase your credibility in a deposition prior to it going to trial.You might also want to look at how many days you spent on a case when talking about your word accomplishments. As we have discussed, accomplishments can be pretty subjective, so if you can get a sense of how much time you spent on a particular case, you can easily claim you were overcharged or undercharged for your time.Remember, there is no set template for writing a sample essay on work accomplishments. However, it is a good idea to know exactly what words or phrases are going to be used in a particular situation.
