3 (a) Use the class diagram to answer the below questions. The class diagram models a system for administering the photography competitions run by a camera club. Member Club name : String membershipNo : Integer Print Competition date : Date Entry abstracts entered title : String firstPrize secondPrize ColourPrint BlackAndWhitePrint Figure 1 a) How many classes are there? Nominate them. b) What kind of relationships are there between classes? Nominate the classes that are connected with certain relationship c) According to Pigure 1 is it possible for a given print to be entered for more than one competition? Explain your answer d) Interpret the association between Member and Club classes. Consider the following scenario: A university consists of several departments. Each department is identified by its name and location. Students are enrolled in different departments. Every student has a student id, student name, address and phone number. A student can be enrolled to exactly one department. A department can have one or more students. Identify classes, attributes, associations and multiplicities. Also draw a class diagram representing this scenario.

Introduction The Object Oriented software model is designed to create a new data type by using the Class structure. Therefore the various operations which define a data type, such as the common operators, assignment, etc., have a software architecture available to create those operations and data types. Assignment Description This assignment is an exercise in creating a complete class definition. A standard way to do that is to use a math data type. Here we define a Rational Number data type in a class called “Rational”. The distinctive feature of this type is the data is kept as numerator and denominator throughout all operations; there is no floating point representation used. The standard math operations, addition, subtraction, etc., are implemented, including the iostream overload. The student will not only come to understand what is required for a complete representation of such a type, but also learn about the internal mechanics of its C++ implementation. The student will be…
Select the class relationship that best describes the following scenario: • Class B creates an instance of Class A in its constructor. • Class B then assigns the Class A instance to one of its own attributes. • Class B does not contain any means for other classes to access the Class A instance. Association (Reflexive) Association (Bidirectional) Association (Directed A to B) Association (Directed B to A) Composition (A as the whole and B as the part) Composition (B as the whole and A as the part) Aggregation (A as the whole and B as the part) Aggregation (B as the whole and A as the part) Inheritance None of the given
Generate a detailed UML class diagram starting from the following problem description: define the required classes, their attributes, the signature of their methods and the relations between the different classes. Problem description: After decades of working with paper records and a personal check-in in the mornings, the daycare ,,Little Caterpillar" wants to digitize their child registration system, and partially automate the check-in process for children. To establish requirements, they have provided their implementation partner with the following information: Parents need to be able to register their children at the daycare when first signing up for their services. Furthermore, they need to be able to drop them off in the mornings, pick them up in the afternoon, and notify the daycare about illness - with the latter feature in particular being highly relevant to the daycare to reduce caller volumes throughout the early morning. Children can be registered either as babies or as…

A company its composed of departaments.The departaments are located in one or more officies.One of them is the main office.Each departament has a manager which is selected out of employees. a) draw a diagram class which constains all the system classes,their attributes,relations between classes,specife the complexity and other elements you find relevant. b) write a java code which constains attributes of classes,acces operations to those.write a main class that would be an instance of the components of company,establish the relation between those and will print the structure of the company.
Class Employee Employee -Name (string) -ID(integer) -Address(string) -Salary(double) -Nationality(string) -ExtraWHours(int) +>( Name,ID) +void setdata( Address,Salary, ExtraWHours) 1. Regarding to the UML diagram create class Customer 2. Create the constructer Employee that read the Employee Name and ID and set the Nationality to Kuwaiti 3. Use the method setdata that set the remaining class data , this method verify that the number of extra working hours is greater than 5 to set the number to ExtraWHour otherwise set the number 1 + Overtime() to this data member + . get methods 4. create gets methods for all data member 5. calculate Employee overtime in Overtime method this method return double value after calculating the overtime by using the following formula Overtime = (Salary * 0.25)* ExtraWHours Test File 1. declare the object Employee1 with Name Fahad and id 7788 2. Ask the user to enter object data (Address, Salary, ExtraWHours) for the Employee1l objects 3. Set the data for…

Create a UML Class Model based on the requirements . Your Class Model is to include: All classes Attributes and Attribute Types Associations Multiplicity Primary and Foreign keys Any Inheritance, Composition or Aggregation. Building Maintenance system. A rental property management company wants to develop a ‘Building Maintenance System.’ This system will be used by the company to manage maintenance requests from tenants in the several rental buildings that it manages in the city. Each building has a maintenance manager. The maintenance manager is responsible for creating accounts in the system for each tenant in their building. A tenant can rent multiple apartments within the same building. Tenants can submit maintenance requests using this system. Each maintenance request will have a request ID, category, and description. The maintenance manager manages a maintenance crew in their building. Maintenance crew members can be members of more than one maintenance team. Maintenance crew…
