Software Requirements Specification (SRS) for Library Management System (LMS)

1. Introduction

1.1 Purpose

The purpose of this document is to provide a detailed description of the requirements for the Library Management System (LMS). It will outline the functional and non-functional requirements, design constraints, and other pertinent information needed for the development and deployment of the system.

1.2 Scope

The LMS is intended to automate the management of a library's resources. The system will handle book inventory, member registrations, and transactions such as book issues and returns. It aims to improve efficiency, reduce manual errors, and provide a user-friendly interface for both library staff and members.

2. Overall Description

2.1 Product Perspective

The LMS is a standalone system that will replace the existing manual process of managing library resources. It will interact with a relational database to store and retrieve information. The system will have a web-based user interface and may later include mobile support.

2.2 Product Functions

• Book Management: Add, update, delete, and search for books.
• Member Management: Register, update, delete, and search for library members.
• Transaction Management: Issue and return books, track due dates and fines.
• Authentication: Login and registration for library staff and members.
• Reporting: Generate reports on library usage, book inventory, and transactions.

2.3 User Classes and Characteristics

• Library Staff: Manage books, members, and transactions. Requires a user-friendly interface and access to administrative functions.
• Library Members: Search for books, check their account status, and view transaction history. Requires a simple interface for ease of use.
• Administrators: Oversee the entire system, manage user roles, and access all functionalities. Requires a comprehensive interface with advanced options.

2.4 Operating Environment

• Web Application: Compatible with modern web browsers (Chrome, Firefox, Safari, Edge).
• Database: MySQL or PostgreSQL.
• Server: Runs on a Java-based server (e.g., Apache Tomcat).

2.5 Design and Implementation Constraints

• Security: Must comply with standard security practices, including encryption for sensitive data.
• Performance: Must handle a high number of concurrent users and transactions efficiently.
• Scalability: Should be designed to scale as the library grows.

2.6 Assumptions and Dependencies

• Users have basic knowledge of computers and web browsing.
• Reliable internet connection is available.
• The system will be hosted on a secure server.
