Question 2: Class diagram with multiplicities, attributes and subclasses (generalization) (3%). Draw a class diagram with multiplicities for the following College Library case: The system stores information about two main things: books and borrowers. A book has attributes for title, author, ISBN, year, and category. The borrower has attributes for first name, last name, phone number and address. Assume that a book must be borrowed by one borrower and a borrower can borrow many books. In addition, also include subclasses for the types of borrowers: student and faculty. Add appropriate attributes for each type.

Question part 3: Draw a UML class diagram with all the classes and relationships.   More info:  In this last and final part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes.   (please see the photo if…

Programming to be used: Java Instructions: Develop a UML class diagram for the following situations. Your diagram should be able to specify correctly the following: Class Name, Attributes with their corresponding data type and visibility, Methods with their corresponding data type. Use the text editor or MS word to present your answers. Scenarios: 1. The university wants you to design an enrollment system. One of the classes to be considered is class STUDENT. A student during registration can have his ID number. Information about the student (eg. First name, middle name, middle initial, contact number, address, birthday) are asked and stored in the system. These information, however, can be edited. After the registration/admission, a student can enroll subjects, can add subjects and can drop subjects. 2. The same University asks you to design a Human Resource Information System. This is a system that records information and generates reports about the employees in the university. Each…

Task 4 Develop a class diagram for following description: Develop a class diagram for following description: The telephone agent uses an order registry and customer catalog to obtain access to an order & a customer respectively. The order registry uses an order number as a qualifier to select particular order instance. A customer catalog uses customer name and phone number as a qualifier to select particular customer. The attributes of an order are the order numbers and time when it is placed. The order consists of many items. An item has item_number, a quantity, unit price. It also has reference to catalog item which represents listing. When an order is cancelled or corrmitted, it cancels or commits each of its items first. When an order's total price method is invoked, the order calls the total price method of each of items and returns the sum.

Given the following specification, design a class diagram using PlantUML. To design the class diagram, use abstract, static, package, namespace, association, and generalization on PlantUML Specification: A school has a principal, many students, and many teachers. Each of these persons has a name, birth date, and may borrow and return books. The book class must contain a title, abstract, and when it is available. Teachers and the principal are both paid a salary.A school has many playgrounds and rooms. A playground has many swings. Each room has many chairs and doors. Rooms include offices, restrooms, classrooms, and a cafeteria. Each classroom has many computers and desks. Each desk has many rulers.

Using C ++ solve the following approach from the information contained in the situation course problem. Situation of the course (propose creative solutions that model some of the information management needs required in electronic commerce transactions) 1. Identify at least 3 classes in the problem situation of the course.2. Design the class model using the UML standard. Use the DIA tool to build it.3. In your class model it is essential that there is at least one composition relationship.4. From the model, code the identified classes in C ++.5. Make sure the attributes and methods you program are complete and correct.6. Take into account all the programming standards that have been outlined in this course.7. Design the general test cases and those that test limit values to ensure that allthe methods work correctly.

Q2. Model a bookDraw a class diagram representing a book defined by the following statement: “A book iscomposed of a number of parts, which in turn are composed of a number of chapters.Chapters are composed of sections.” First, focus only on classes and associations.Add multiplicity to the class diagram you produced.Refine the class diagram to include the following attributes:• Book includes a publisher, publication date, and an ISBN• Part includes a title and a number• Chapter includes a title, a number, and an abstract• Section includes a title and a numberConsider the refined class diagram. Note that the Part, Chapter, and Section classes allinclude a title and a number attribute. Use inheritance to factor out these two attributes .

b. Create an UML class diagram that models the data relationships described in the following paragraph. • To be a collector you have to have one or more collections. • Each collection must have 2 or more items. • Each collection belongs to one collector. • A collection is made up of items owned. A particular item may be in more than one collection (i.e. an old Coke sign may be in both a Coke memorabilia collection and a sign collection.)

java    Prompt Create a UML diagram modeling any classes and relationships that you want. The classes and relationships used should make sense for a program that is modeling your chosen classes. Your model must have at least four classes and one example of abstract inheritance (abstract classes or interfaces), but there is no maximum limit to your diagram's size or complexity. Provide enough members inside of each class that it is clear what a program that uses these classes might be trying to accomplish. Think about what kinds of objects you might want to model in your code. Are you modeling real objects, or abstract ideas? Is there a type of classification you can use that would make it easy to come up with derived classes? What types of variables and methods would your classes need to be functional or work together. Your classes don't all need to be linked by inheritance - maybe you can come up with multiple different object types that work together in a larger program? An easy way…

Question 23 To show inheritance in a UML class diagram you would use a solid line with a fat-headed arrow. The line should be attached to the child class and the arrow should be attached to the parent class. True False

Both professors and associated professors can be generalized as academic staff. Both academic staff and administration staff can be generalized as university staff.

"complete and sufficient", two important characteristics of a good class design, when a class is "incomplete", or "insufficient", how can that effect dependency relations of the class? For example, I argue that an incomplete class becomes highly dependent on other classes (but these classes might not depend on the class in the same way). What do you think? why are these characteristics important? A good discussion can benefit from examples, please provide some.
