Q2

Instructions: All Questions are based on the following case study. 1 You are required to design a mobile phone application to run on iOS and Android devices. 2 The app is envisioned to be Prisma-like, but more versatile. 3 4 Users can either capture a photograph through the phone camera or choose an existing 5 photograph from their collection. Users can then ask the system to apply styles to the 6 chosen image. Styles can be of many types. Some styles are just transformations, i.e. 7 rotation, cropping, brightness, face-centering, etc. Other styles are actually images, whose 8 visual style will be transferred to the chosen image (similar to Prisma). There are still 9 other types of styles that may require integration with some third-party web service. Users 10 can choose one or more styles to be applied to a chosen image(in any order or 11 combination). 12 13 The system should store the frequency in which styles or style combinations are used. This 14 is to make sure that when users are selecting styles or style combinations, they see their 15 most frequently used ones first, in order of usage frequency. 16 27 There is an online market of styles. Users can publish their styles in the market. Whenever 18 someone buys a style from the marketplace, the style is added to his/her installed 19 application. Also, whenever a style is purchased the style publisher is sent a notification 20 about the purchase. 21 22 After the application of a style on a chosen image, if the user so chooses, he/she can share 23 the resulting image on social networks, i.e Google+, Facebook, Twitter, etc. Questions: Q1. Identify (name) the design pattern(s) that you will use to design a solution to the problem(s) mentioned in lines 4-11. Q2. Draw a UML class diagram outlining the design of your solution to the problem(s) mentioned in lines 4-11. Your design must integrate the design pattern(s) you mentioned in your answer to Q1.
