- Course: Database Systems: Design and Application Web Shop scenario: A supplier (Supp-#) processes many purchase orders (PO-#) and sells a number of products (Prod-#). A product is sold by only one supplier. Each of the purchase orders that a supplier may process includes several products. The relationship between order and product is defined as "Line Item". A customer (Cust-#) may place one or more purchase orders. A purchase order may be placed by only one customer. Assignment requirements: Answer the following questions using above scenario: Identify the entities and attributes that required to draw the ER diagram. Integrate the entities with appropriate relationship and design the unified ER model.> Create UML Class diagram for e-library system as described, make sure to show attributes, generalization where appropriate. operations, multiplicities, and aggregations/compositions, A library system has materials which would be books, journals, or CDs. All library material (books, magazines, and CD) has a unique identification number and a title. Books have one or more authors, journals have producer, while CDs have entertainer. all library materials can be loaned to users, users have user-id, user-name, birthdate (day, month, and year), age and phone-number. Users can loan any material, for each loan the library records material-id, the user-id, loan-date (day, month, and year), and loan time (hour, minute), and loan counter (shared)Given the following UML diagram: Student - studentID: String + getStudentID(): String + toString(): String Person - lastName: String - firstName: String - dateOfBirth: Date - address: Address + getName(): String + getDOB(): Date + getAddress(): Address + toString(): String Professor - employeeID: String + getEmployeID(): String + toString(): String Write an implementation for the class Professor. DO NOT include or implement any constructor for this class. There are no abstract methods/classes in this example. toString method will return any simple String that contains firstName and employeelD only; no less, no more!! Assume firstName was defined as protected in class Person. You are not allowed to add implementation for any class or methods other than what is listed in the question statement. 2
- Final Project By Java OOP A simple Library Management System aims at developing a computerized system to maintain all the day-to-day activity of a library. This functional project handles data of books and their copies, users that can be either students or teachers as well as book loans. Each book has an id, title, publisher, author, year, number of copies, copies of the book, financial value and status(true if at least one copy is available). Each copy has id, status whether a copy is available to be borrowed of not and insert date. A user has id, first name, last name, password and registration date. In addition to the total fine which is the total of each fine the user get for every late return of a book. Students has major whereas staff has department. When borrowing a book, the system recording the copy of the book being issued (borrowed), the borrower and the date at which borrowed. The system must first check for the copy availability and record the return date which is 3 days…The "SUPERVISES" Relationship is considered as: EMPLOYEE SUPERVISES O 1. Ternary Relationship O 2.
