You should attemptALL parts of the question. Your answers should be written in the blue answer book.Case Study DescriptionI Was There is a new web-based software product being developed to allow travellersto share their travel memories. Its main function is to enable travellers to upload theirown content and to assemble it into complete journeys for their own use and also toshare with others.The main role of this application is for travellers, who have registered with the system,to be able to upload, edit or remove their own travel memories. These memories canthen be used to create journeys, which are collections of memories. Registeredtravellers can also specify access rights to their own travel memories and journeys,either private, public or friends only. It is also possible for those who have notregistered to access the site. They can look at other peoples memories and journeysthat have public access, but cannot upload or edit anything. The site has a moderatorwho is able to review content (for example to check for inappropriate content) and toremove it if necessary.Travel memories may be photos, videos or documents. All of these will have a nameand a date, and will be associated with a single location. A location includes a textdescription and its GPS coordinates.There are two types of document; stories, and reviews. These both have an author,but only reviews have a star rating. A story may optionally link to another story thatfollows on from it.As well as a collection of travel memories, each journey contains the travellers owncommentary which will include the start and end dates of the journey. Deleting ajourney will not delete the travel memories within it, but the commentary will be deleted.Case Study QuestionsWhen answering questions 1 and 2 you should adhere to good namingconventions and name all your model elements (for example use cases,associations, attributes, etc.) in an appropriate way. You should clearly stateany assumptions you make.1. Draw a use case diagram for your system from the requirements givenabove.(15 marks)2. Draw a domain model class diagram for this system. Your diagram shouldinclude relevant classes, associations, attributes, multiplicities, etc.(20 marks)3. Draw an activity diagram for a person interacting with the web based system.(15 marks)+ + + + + + + +如有需要，请加QQ：99515681 或邮箱：99515681@qq.com
