📘 Linux Lab#SE00-3: Library Model

  1. Create two new feature for a library management system:

    1. to track the library’s inventory of periodicals such as newspapers, newsletters, and magazines.
    2. that allows the librarian to add, remove, and update the periodicals in the inventory, and also show all the periodicals in the inventory.

  2. Create five new classes: Periodical, Newspaper, Newsletter, Magazine, and Edition.

    1. In the Periodical class, define fields such as title, publisher, publicationDate and methods such as getTitle(), getPublisher(), getPublicationDate()
    2. In the Newspaper class, define fields such as edition, section and methods such as getEdition(), getSection() and also inherit fields and methods from the Periodical class.
    3. In the Newsletter class, define fields such as frequency and methods such as getFrequency() and also inherit fields and methods from the Periodical class.
    4. In the Magazine class, define fields such as category and methods such as getCategory() and also inherit fields and methods from the Periodical class.
    5. In the Edition class, define fields such as issueNumber, volume and methods such as getIssueNumber(), getVolume()

  3. Define the relationships between the classes, such as inheritance, composition, and use.

    1. The Newspaper, Newsletter, and Magazine classes inherit fields and methods from the Periodical class. The Periodical class **uses** the Edition class.

1 Basic UML

This Mermaid class diagram describes the classes and their relationships in a library management system.

It shows the classes involved in the process of a library member checking out a book and a librarian helping him.

  1. The Member class has a method checkOutPublication() which represents the action of a library member checking out a book.
    • The Borrow class is associated with the Member class, it has fields such as fromDate, toDate and borrowStatus which describes the borrowing time and the borrow status.
  2. The Librarian class has a method addPublication(), removePublication(), holdPublication() which represents the action of a librarian adding, removing and holding a publication.
    • The Issue class is associated with the Librarian class, it has fields such as publishDate, unpublishDate and manageDate and issueStatus which describes the publishing and unpublishing of the publication.

class Publication {
  -title: String
  -year: int
  -author: String
  -statusPublication: enum
}

class Borrow {
    +fromDate
    +toDate
    +borrowStatus
}

class Issue {
    +publishDate
    +unpublishDate
    +manageDate
    -issueStatus
}

class Member {
    -idMember: String
    +checkOutPublication()
    +returnPublication()
    +holdOnPublication()
}

class Librarian {
    -idLibrarian
    +addPublication()
    +removePublication()
    +holdPublication
  
}

class Person {
    -name: String
    -surname: String
    -address: String
    -age:int
    +getPublications()
}

Person --> Member
Person --> Librarian

Borrow --> Publication
Librarian --> Issue
Issue --> Publication

The Publication class is the superclass for all types of publications, it has fields such as title, year, author, statusPublication which represents the properties of the book.

In summary in this class diagram:

  • the Member class is checking out a book: the Borrow class helps to the member class,** it keeps track of the borrowing time and the borrow status.**
  • the Librarian class is helping the member by adding, removing and holding a publication: the Issue class is associated with the librarian class, it keeps track of the publishing and unpublishing of the publication
  • the Publication class is the superclass for all types of publications, it has properties such as title, year, author, statusPublication.

2 Large UML

This mermaid UML is a class diagram that describes the classes and their relationships in a library management system.

The Interface class represents the user interface that allows the user to manage the library, search for publications, check out and check in publications, add, remove and update publications.

  • The Publication class is the superclass for all types of publications, which includes:

    • Book, Journal, Magazine, ReferenceBook, HandBook, and Movie.
      • Book class has a method getAuthor() and getISBN(),
      • Journal class has getISSN() and getAuthors(),
      • Magazine class has getIssue() and getAuthors(),
      • ReferenceBook class has getEdition() and getAuthors(),
      • HandBook class has getSubject() and getAuthors(),
      • Movie class has getDirector(), getReleaseDate() and getAuthors().

  • The Borrow class has properties fromDate, toDate and borrowStatus which describes the borrowing time and the borrow status.

  • The Issue class has methods publish, unpublish and manage which describes the management of the publications.

  • The Person class is the superclass for Author, Member, and Librarian.

    • The Author class has getBooks() method,
    • Member class has getBorrowings() method,
    • Librarian class has add(), remove(), and getPublications() method.
    • The Student class has getID() method,
    • Teacher class has getDepartment() method,
    • Faculty class has getPosition() method.
