QUESTION 3 (Conceptual Data Models) Prepare an Object Class Diagram for a Wedding Cake Ordering system with the following description: For each Customer, the system must store Customer ID, Customer Name, Customer Mobile No, Customer Email, and Customer Password. For each order, the system must store Order ID, Cake ID ordered (F.K.), Order Date, Delivery Date, Delivery Time, Delivery Venue Address, Order Total, Customer's ID, who placed the Order (F.K.). For each Cake, the system must store Cake ID (P.K.), Cake Name, Cake Type, Cake Price, Recipe No (F.K.). Cakes may be of two types: o Tiered Cakes, for which the No-of-Tiers must be stored A Tiered cake can have a maximum of 3 tiers, prepared using same Recipe, or each tier can use separate Recipe (i.e. a Tiered Cake consists of number of Recipes, max 3) Cup Cakes, for which the No-of-Batches prepared must be stored The Cup Cakes are prepared in batches, and each batch can use same Recipe, or maximum 2 different Recipes (i.e. Cup Cakes may also consist of number of Recipes for a batch, max 2) For each Recipe, the system must store Recipe ID (P.K.), List of Ingredients needed, Cooking time, and the Cake Id (F.K.), for which the Recipe is used. Present the Object Class diagram for the description provided above, showing all classes/sub- classes/associative classes, the different types of relationships (including generalization/specialization relationship, aggregation, etc., if any) with their multiplicities at each side of the relationship, using correct notation in your answer.
