Bookstore application for Java Project
The focus of this software will be to manage all important steps of a Library. The software should keep data about all the books in the library, such us ISBN of the book, title, category of the book, supplier, purchased date, purchased price, original price, selling price, author, stock. At the same time, we should keep track of the sold products by bill number (or Order ID), their sold quantities, prices, and date of transaction. The application will have a three-level user system: Librarian, Manager and Administrator. Each will have different views and usage of the software. Note that each of the users has a username and a password to enter the software (obviously a role as well).
Librarian -> Has the right to check out books that a customer may need from the bookstore. This means that the librarian should create a bill and enter the data of the bought books, such as ISBN of the book and its quantity. If the book is out of stock or does not exist, give an alert to the librarian. The software should provide him the total amount of the bill, and it should be in printable format (BillNo.txt). The updates in the software file should be done automatically by adding the data into the respective files.
Manager -> The manager has the right to supply the bookstore with the needed books. So, he/she may enter the stock the new book category, and/or add books of the same category to the stock of the bookstore. The manager should be informed when entered in the system if there are few (usually less than 5) items of a book in the bookstore stock. The same user may also check the performance of the librarians by checking their total number of bills, books sold, and the total amount of money made for a certain date or between a certain period of time. Also, the statistics about the books sold and bought should be provided to them whenever requested from them daily, monthly and/or total.
Administrator -> The administrator has the right to manage almost everything that Librarian and Manager does. Beside them, he has the right to manage the employees (Librarian and Manager), by registering, modifying, and deleting them. He may keep data about them such as: name, birthday, phone, email, salary, access level, and other information about them. The software should provide to him also data about total incomes (total of books sold) and total cost (total of items bought and staff salaries) during a period. Another important role of the administrator can be to revoke permissions from librarians or managers. This means that the permissions should be role-based. This is not mandatory, but you get extra points if you can manage to implement it, otherwise keep the permissions static.
The data of the bookstore should be stored in binary and text files and managed appropriately by using the proper Objects.
The students should organize the classes in packages and make use of proper data encapsulation.
The requirements include:
- Encapsulation, inheritance, polymorphism, abstract classes and interfaces
- File Handling - Text and Binary IO (both of them)
- Validation of Input (Very Important)
Usage of String Functions and/or Regular Expressions for validating the input 4. Exception Handling (try{}catch(){}finally{}, custom Exception Classes - JavaFX UI and Graphics (everything we have covered)
- JavaFX Events (Event handling, Inner Classes and other things related to the lesson)
- The project should be organised in Model-View-Controller, where the model should fulfill all requirements from 1 to 4 and View-Controller requirements 5 and 6.
Note: Menus are a must for all projects, the application should be fully interactive, and it should have a login system with different levels. More may be discussed during lessons. Be aware: The Final submission of the project should include all source files (as a project in a .rar or .zip format). In case you do not present your project, you get 0 points. The name of the project should be the same as your username and zipped in a file like nsurname22.zip. The project should also have a note.txt which has a list of username and password to access your application.
WARNING: FXML (or Scene Builder) is not permitted, and will not be evaluated in the project.
