Library System Project The library at the University stores different items that can be borrowed, including...
This project supposed to develop a database system for a library for a university. The system contains information about books, book authors, students, and faculty. Students and faculty are allowed to borrow books from the library. You should design the system to contain entities and attributes to store data that makes the system able to report the requested information by executing the queries. SQL Queries: 1. List the names and email for students who borrowed books along with the number...
Design an ER diagram for a library management system. The library manages books, members, and books borrowed by members. The library has several branches around the city. Each branch has a name and address and is identified by a branch ID. Each book in the system is identified by a unique ISBN along with its title, author(s), and publisher. A publisher is identified by its name, address, and phone. Note that publishers may be based anywhere around...

Case Study:UniversityLibrarySystem This case is a simplified (initial draft) of a new system for the University Library. Of course, the library system must keep track of books. Information is maintained about both book titles and the individual book copies. Book titles maintain information about title, author, publisher, and catalog number. Individual copies maintain copy number, edition, publication year, ISBN, book status (whether it is on the shelf or loaned out), and date due back in. The library also keeps track...
Can somebody help me with the Use Case Diagram . I am confused of what I am suppose to do. Here are the instructions : Your team should produce a Use Case Diagram and the associated Use Case Descriptions/Narratives for all the use cases in the diagram. The resulting document should havethe “professional look” and produced by a word processor, graphics/presentation/drawing software, and/or a CASE tool (e.g., Microsoft Word, Microsoft PowerPoint, ArgoUML, Dia, Visual Paradigm, Visio, etc.). All project documentation...
The CIS Department at Tiny College maintains the Free Access to Current Technology (FACT) library of e- books. FACT is a collection of current technology e-books for use by faculty and students. Agreements with the publishers allow patrons to electronically check out a book, which gives them exclusive access to the book online through the FACT website, but only one patron at a time can have access to a book.

A Call number uniquely identifies each item in the library. The phase 1 of the software involves Adding a new item to the library: The details of the...
In this project, you will construct an Object-Oriented framework for a library system. The library must have books, and it must have patrons. The patrons can check books out and check them back in. Patrons can have at most 3 books checked out at any given time, and can only check out at most one copy of a given book. Books are due to be checked back in by the fourth day after checking them out. For every 5 days...
IN C++ My project will be a library management system. It will have seven functions. It HAS to contain: classes, structures, pointers and inheritance. fix code according to below 1. Add a new book allows the user to enter in book name and book code Book code has to be in # “Invalid book code” “book name has been added to library” book code will be used to borrow books 2. Add a new user must use first user must...
