- An art museum owns a large volume of works of art. Each work of art is described by an item code (identifier), title, type, and size; size is further composed of height, width, and weight. A work of art is developed by an artist, but the artist for some works is unknown. An artist is described by an artist ID (identifier), name, date of birth, and date of death (which is null for still living artists). Only data about artists for works currently owned by the museum are kept in the database. At any point in time, a work of art is either on display at the museum, held in storage, away from the museum as part of a traveling show, or on loan to another gallery. If on display at the museum, a work of art is also described by its location within the museum. A traveling show is described by a show ID (identifier), the city in which the show is currently appearing, and the start and end dates of the show. Many of the museum works may be part of a given show, and onlyactive shows with at least…3 (a) Use the class diagram to answer the below questions.

Draw a sequence diagram for this use case Use case name Plantrip Entry condition The Driver logs into the trip planning service. Flow of events 1. The Driver enters constraints for a trip as a sequence of destinations. 2. Based on a database of maps, the planning service computes the shortest way of visiting the destinations in the specified order. The result is a sequence of travel segments concatenated together and a list of directions. 3. The Driver can revise the trip by adding or removing destinations. Exit condition The Driver saves the planned trip by name in the planning service database for later retrieval..
- 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…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…A trading company wish to maintain a database of its staff, the database is Include name, age, salary, and department distribution into a members of classes are shown in the following fig. find: Read data for all classes Display all database information where the salary is greater than 1000000?

User Class – It manages all operations of user. Librarian Class – It manages all operations of Librarian. Book Class – It manages all operations of books. It is basic building block of system. Account Class – It manages all operations of account. Library database Class – It manages all operations of library database. Staff Class - It manages all operations of staff. Student Class - It manages all operations of student. Required You are required to create a complete class diagram.3 (a) Use the class diagram to answer the below questions.

- 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.)Draw a specification level class diagram for the following:Mary has completed her assignment for Introduction to Programming course and has madethe required zip file. She logs into the Automatic Submission System from the computerlaboratory at University, selects assignment 1 for Introduction to Programming course andsubmits her zip file. The Automatic Submission System gives her a unique key to identifyher submitted work. She prints the key and then logs out of the Automatic SubmissionSystem which contains the submitted assignments of all the students.Course: System Analysis And Design , ITMA 411 State refers to an object’s current status. A state transition diagram shows how an object changes from one state to another, depending on events that affect the object. All possible states must be documented in the state transition diagram.In a state transition diagram, the states appear as rounded rectangles with thestate names inside. The initial state represented as a small circle, and it is the point where the object first interacts with the system. Lines used to show direction and describe the action or event that causes a transition from one state to another. The final state represented as a circle with a hollow border.In this assignment you are requested to create State Transition Diagram for the student registration system. Kindly Use Lucid Chart
