UML is not a stand-alone programming language like Java, C++ or Python, however, with the right tools, it can turn into a pseudo programming language. The main drawback of using CASE tools is that they require a certain level of expertise, user training as well as management and staff commitment. Often, this is done by using CASE tools (Computer Aided Software Engineering Tools). In such a case, the UML diagram serves as a complete design that requires solely the actual implementation of the system or software. Backward Design – After writing the code, the UML diagrams are drawn as a form of documentation for the different activities, roles, actors, and workflows.Many design issues or flaws can be revealed, thus improving the overall project health and well-being. This is done to get a better view of the system or workflow that you are trying to create. Forward Design – The design of the sketch is done before coding the application.However, this is only a top-level view of the system and will most probably not include all the necessary details to execute the project until the very end. UML diagrams, in this case, are used to communicate different aspects and characteristics of a system. UML itself finds different uses in software development and business process documentation: Sketch It was later adopted as the standard in 1997 and has remained the standard ever since, receiving only a few updates. The need arose for a more unified way to visually represent those systems and as a result, in 1994-1996, the UML was developed by three software engineers working at Rational Software. In the 1990s, there were several different ways to represent and document software systems. UML was created as a result of the chaos revolving around software development and documentation. By using visual representations, we are able to better understand possible flaws or errors in software or business processes. As the old proverb says: “a picture is worth a thousand words”. It is based on diagrammatic representations of software components. In fact, it’s one of the most popular business process modeling techniques. Simply put, UML is a modern approach to modeling and documenting software. UML is an acronym that stands for Unified Modeling Language. A UML diagram is a diagram based on the UML (Unified Modeling Language) with the purpose of visually representing a system along with its main actors, roles, actions, artifacts or classes, in order to better understand, alter, maintain, or document information about the system.
