Introduction

1.1 Purpose The purpose of this "new" library system is to help the students in searching, reserving and checking the availability of the book. The existing system will be improved, the Online Public Access Catalog (OPAC) of the school wherein the students can search, reserve and check the availability of the book even at home using the "Online Library System.". The students will log in using their own account (for example, their own CAC number). In this way, the waste of time, money, etc. to go the library and check the status of the books (details of the book, deadlines for the books to be returned, and duration of borrowing the book) would be avoided. The online library system will be having an "e-books" section, this section is where the students can research or read a book using their own computers. There would also be a “thesis section” wherein all the approved thesis or dissertations of the students would have an electronic version.

1.2 Scope The existing library system only covers the usage of OPAC inside the school, the library to be exact. This system will cover some of the old features of the library system and improve it for the better use of the students. The Online Library would be providing the books in PDF format. Only the students enrolled or studying in DBTC are given individual accounts, which have the full privilege on viewing the online library. Upon enrollment, each student would be given a respective username and password. The accounts of each student of the school contain their profile and the records of their borrowed books. Account holders would be reminded on their incoming deadlines and overdue books upon logging in. Full-view of books is given privilege to account holders. Those logged in can have a preview or abstract of other books like dissertations or they could go to the school’s library and view the hardbound books provided.

Library - a collection of literary documents or records kept for reference or borrowing Online library -

Overdue -

past due; not returned at the scheduled time

Card catalog -

OPAC (Online Public Access Catalog) -

1.4 Reference Old library system: Online Public Access Catalog (OPAC) The database of the grade school, high school and college can be accessed from each library or centralized. There are modules such as the security system wherein the student would scan their identification cards in and out of the library. In this security system, the number of users and their time inside the library would be known. The advantage of having a web based library system is that you could do library work even at home. You can check the availability of the books, reservation, circulation, catalogue, clearances (overdue books, etc.) and other matters online. Each student would have an account to log in to and have a view of the books in the school’s library. Those books would be scanned and formatted to a PDF file, called e-books.

CS Software Developers, Inc. 1.5 Overview

The library of other schools can be treated as a normal library. There were no databases for the books, their locations and their authors. Students have to manually search them through the use of cards bearing the codes from the Dewey decimal system. In times, these cards are misplaced or even lost, causing confusion among the students and the administrators in the library. To help solve this problem, the school instituted a library system for the library. Although it eased up some of the problems in the library, it wasn’t fully functional. So this study will be about improving it, the previous library systems.

To improve the existing traditional library systems, each student will be given an account upon enrollment. This account will have full access of the online library system of the school. A more comprehensive search engine will also be established to provide more exact retrieval of search results. A non-student can log in as a guest, but will just have a limited access of the system. For security purposes, each student will have to swipe their ID’s when coming in the library and going out. By this, a student’s stay inside the library can easily be monitored. Databases can also be accessed.

General Description

2.1 Product perspective

The new library system should be able to provide a basic and easy interchange of information which gives more specific and up-to-date information on books in the library including its deadlines and specific book details. It should be easily accessed and always updated specifically on the book's circulation. It should give ease to students by allowing them to view the books through e-books in their own computers. It should give a benefit to librarians because their work like file organizations could also be done anywhere, even at home. It gives them the time to finish their pending works and be submitted up to their deadlines.

2.2 Product functions

Administrator The administrator would log in with their respective accounts. There would be three options, cataloguing, OPAC and circulation. In the cataloguing, the administrator can add, edit, and delete books from the database. The availability of the book could also be changed in that section. The books returned or borrowed from the library would be updated by the librarian. In the OPAC, the administrator can also add, edit, and delete books from the database according to its category in the e-thesis, e-books and printed books section. In the circulation, you can search the name of the student and modify their accounts. The administrator can add, edit and delete the borrowed books from the student account. The accounts of the students are where the status of the student is cleared. All unreturned books past their due date and delinquent users would be recognized and sent a notice. All these updates would be sent to their accounts. The statistics would be updated also upon modification of accounts in the circulation. The most borrowed books, most frequent borrowers or most active readers and peak months where books are frequently borrowed are generated in the statistics. It can be seen under the section of cataloguing. The administrator would log out after the changes made in the system.

CS Software Developers, Inc. Students The students would log in their accounts which are provided upon enrollment. They would be able to search a book, check its availability and reserve it. In the e-books, e-thesis and printed books section, students are allowed to read the .pdf formatted books. Registered students are only those allowed to read electronic theses or dissertations. In their own accounts, they are able to see information about their account and their borrowed books.

2.3 User characteristics

A user can only have an account username and password so if he joins or enrolls the College then only he can login. This prevents misuse and unauthorized access. For the non-students, they could log in using the guest account.

2.4 General constraints

There is a server limit on how many users can access the online library at once. Network traffic would be experienced if the server limit is breached.

2.5 Assumptions and dependencies

The storage capacity of the online library system should be able to contain all soft copies of the current books in the library, along with all their details. It should also work at high speed given that the library books circulate day by day. Certain details of the books will change every time each book is borrowed by a student. The main server, which would maintain the system, should have a database backup for the books, so as to avoid unwanted data loss. A generator will also be installed in case sudden power loss is experienced.
