Question 5 According to the Object Management Group (OMG) who maintain it, the Unified Modelling Language (UML) is a "graphical language for visualizing, specifying, constructing, and documenting the artefacts of distributed object systems". While this course (and others) teach the use of UML, Petre (2013) finds that many companies do not use it, or only use selected models, and even these are often used in formally. To what extent do you think UML should be used in a software development project for a web application? Which UML models (diagrams) do you think may be of most use in this context? Use examples and appropriate references to support your answers. References do not need to be from academic journals or books; references to blogs/wikis may be used. However, consider the authority of the author e.g. a comment from an unknown contributor on stack overflow is probably not useful, a comment from a blog or wiki from someone respected in the software engineering community such as lvar Jacobson, Robert Martin, Ron Jefferies, Martin Fowler, or an organisation such as Google or Microsoft, is likely to be more relevant. Your answer must not exceed 500 words (excluding diagrams and references)
