Your task is to perform the steps of logical database design, i.e. to transform a conceptual schema given above into a collection of relational schemas. Before transforming add the attribute 'phone' to the BRANCH and the attribute 'mobile-phone' to the CUSTOMER class. Draw the resulting conceptual schema adding your name, student number and the date to the drawing. Use UMLet and paste images of your drawings into your Microsoft Word document using the template provided. List the names of attributes, primary key, candidate keys (if any), and foreign keys (if any) for each class in the relational schema. Assume that an association method is used to implement the generalisation. Show your working and explain as you step through the transformation process.
