As a software engineer you are required to produce designs to fulfill user requirements as described in SRS or User Stories. Suppose your software application needs to address the situation as given in respective scenarios (a-e). Your task is to answer the following for each of the given scenarios (a-e): [CLO-3]i. In terms of suitability which design pattern is most appropriate to address each situation? ii. Design/draw generic UML diagram to represent each situation.(a) You are writing a module for a university application that would allow students to apply for online clearance for final transcript issuance. As per policy students’ clearance is done from several offices before request for degree or final transcript could be approved.(b) After graduation, students would like to seek and search admissions in foreign countries. Usually students visit each university-website one by one. Generally they want to know about university ranking, fee, working opportunity, visa requirements etc. You are designing a web portal that would provide list of universities students may navigate from a single interface to access all these kind of information.(c) Some students do not share their academic performance with their parents or give them wrong information. University is planning to communicate student’s academic performance including their attendance status electronically to all the possible contacts (landline, cell phone, email address) of the guardians that were provided by the students at the time of their admission.(d) Imagine that you are implementing a file system. The main abstractions in your design would be files and directories. Directories can contain zero or more files or directories. You want to treat directories and files in a uniform way, e.g., both will have name and will provide operations to stream content in and out, and to list children.(e) Suppose you commute to the university every day. Several options exist, such as driving your own car, taking a taxi, lift, bike, or a pick and drop service. For some students some other options are also available as a mode of transportation to the university. Any of these modes of transportation will get you to the university, and they can be used interchangeably depending upon the situation. You must choose the best option based on tradeoffs between cost, convenience, and time.
