Library System Database Design
Title: Library System Database Design
The Library System is a computer-based application used to automate a library. It allows the librarian to maintain the information about books, magazines and other library materials. It also allows the librarian to maintain and organize the information about its clientele or borrowers.
This project focuses on the automation of system process of adding newly acquired books, borrowing books and borrower’s information, returning of books, searching for the location of the books and printing of the inventory of books in the library.
The automated library system provided electronic list of books and generated report related to transactions in the library such as borrowing and returning of books. In addition, automated library system has also a database feature which allowed the end-user to back-up and restore information in the database.
This was also designed based on the needs of the office and its clientele. Transactions were done instantly, securely, safely, quickly and efficiently.

The query below will display the list of due date borrowed books
msql = " SELECT tblbook.booktitle, tblborrowedbook.dateborrowed, tblborrowedbook.duedate, Concat(tblborrower.lname, ', ', tblborrower.fname, ' ', tblborrower.mname) as bname " & _
" FROM tblbook INNER JOIN (tblborrower INNER JOIN tblborrowedbook ON tblborrower.ID = tblborrowedbook.borrowerid) ON tblbook.ID = tblborrowedbook.bookid " & _
" WHERE CURDATE() > duedate and bstatus ='Borrowed' or bstatus='Rent'" & _
" GROUP BY tblbook.booktitle, tblborrowedbook.dateborrowed, tblborrowedbook.duedate, tblborrower.fname, tblborrower.mname, tblborrower.lname;"

- Majority of the respondents claimed that the performance of the manual system in terms of speed, accuracy, security and usability is good. Their current system is okay, but most of the respondents want to have the better or best performance of the system.
- There is a need to change the manual system into an automated system for a possible improvement.
- Most of the respondents prefer to replace the current library system into an automated system for it would be a great help to improve the library transactions.
- The need to replace the current system into an automated system is highly agreed by the respondents.
