Overview: The internet is an ideal medium for locating missing persons, cats, phones, bicycles, artwork etc. etc... For example, see the cat finder site. Some of the issues in developing a service to help find missing things ("subjects") concern requirements modelling, implementation and communication. There are many web sites available for other subjects and many ideas as to how the task should be carried out. These sites have different business models, different ways of submitting data (email, Web, SMS) different approaches to privacy, different data models and of course different server-side technologies. Before developing a site for a different subject area, it is useful to look at similar sites, to consider what data model supports the site and what functionality it supports. In this coursework you will undertake three work packages, each of which must be checked and reviewed by a tutor (via email) before proceeding to the next work item. These work packages lead to the development or the research prior to the development of a small part of a new site to support your selected subject. WP2. Design (30 marks) Select a missing subject to be agreed with your tutor and identify the required functionality of the site and the information to be held to support that functionality. A good mark in this work package will be gained for a correctly structured model, capable of being used to generate a valid and appropriate SQL database which can support the required functionality. Deliverable: Commented data model to be viewed as a diagram (gif or png) embedded in a HTML file
