Summary

This NodeJS-based website is a reliable web application that saves time and money. This must be implemented in most of the information technology industries. It is user-friendly software, through which users can easily interact and easy to search for and buy products. This turns out to be great usage.

With the rapid growth of the internet and the world wide web, everything is going online. This website is developed by keeping in mind the easiness of interaction by the users so that they get a very user-friendly environment while surfing the website. Such compatibility of this website enables it to attract users to visit the website more frequently

The system is capable of maintaining details of various users, sellers, and products and storing all day-to-day transactions. The central concept of the application is to allow customers to search, compare and purchase products using the internet. The information pertaining to the products is stored on a NoSQL database on the server side. The Server process the customers and the orders and stores them in the database. 

Future involvement with the project

We will keep on improving our project in the future by adding more and more modules in the system as per the needs of the users. 

Limitations

Our project was limited in time and cost which is a limitation. If provided with more time and cost, we would have done better using the better infrastructure.

We developed the project on a local offline server, though we could have used an online one if provided with more cost.

Library Management System BCA 4th Semester Minor Project using SQL and PHP

ACKNOWLEDGEMENT

We truly resolve to acknowledge the opportunity provided to us by the Institution, respected teachers, and family.

We intend to show our gratitude for all the support and guidance we got from our teachers, classmates, and all individuals who helped us at any point in this project.

This whole process we went through in bringing out this project was a great source of knowledge and valuable experience, which would for sure, come in handy for us in any future we will have to bring out another such project.

This has been a period of time over which we learned about technological and logical aspects of the field where we are going to land soon, we feel indebted for being so well equipped with all the knowledge and experience we gathered here.

Introduction 

Surface details:

Our project entitled “Library Management System” is designed to bring ease to both the library staff and the students seeking for issuing books.

It is designed with features that reduce the effort for the staff and increase convenience for the readers, Being a Web Based application, it is easy to Run and adapt in almost all conventional environments.

Any moderate user can easily learn and operate this system 

Scope:

This System can work fine for all most every library, where desired,

This cuts off a lot of human resources required to maintain the library, hence saving money too.

It has fluid UI and UX which can be learned and adapted quite quickly by any category of user.

This system extends its use outside the library with is easy to adapt interfaces for readers

Objective

The Objective of this System is to reduce effort and increase convenience in the management of libraries.

It allows users to hold a book for 24 hours so that no one can get it issued before they reach the library.

It will save time in the calculation of fine

Students will always stay notified about generated fines via their online accounts which they can access from anywhere.

  • It will make it easier to search for books.
  • It will help keep track of bookholders.
  • It will keep Libraries less crowded.
  • It will save money as fewer human resources will be required.

About the existing system

Currently, libraries need to maintain bulky files to record books and the individuals occupying them.

Fines are calculated manually by going through bundles of records.

Need to manually check for availability of books in the library

The process of issuing a book involves designated officials making entries in registers manually, which takes plenty of time.

Disadvantages of the Present System:

The current system is full of flaws:

  • A lot of Human Resources is required to maintain such a system much cost and hard to operate and maintain.
  • A lot of money is wasted in maintaining these records
  • Paper is wasted
  • A lot of time is consumed in the process of searching a book, making its entry, and retrieving any previous record.
  • Availability of books cannot be assured without physically searching the library
  • People need to travel to the library to know whether a book is available. 

Proposed System

The System we developed comes with all solutions to the drawback of the previous system.

Some of them are listed below:

  • Search books from anywhere.
  • Put the book on hold for 24 hours so that no one else can take it before you
  • Release the book if you don’t want to hold it anymore
  • A panel for users to check their hold and issued books
  • Easy login and registration System.
  • Automated Fine System
  • One-click book Issue
  • Easily return book
  • List of trending books.

Feasibility Study

This document enables proper decisions to be made over the progress of the project, by studying various aspects of feasibility associated with it

Such are listed below:

  • Cost: as it is a web-based project it needs to be hosted over the server to be accessed by users, but the efficiency which comes with the product shadows this cost, as it reduces money being spent on human resources
  • Time: The time invested in this project is also justifiable as keeping the yield into consideration.
  • Technical: All technological tools used to make this project are conventional easy-to-use ones, and they are easy to maintain too.

This project can be easily upgraded and maintained as it is designed in a standard manner and is easy to understand.
