📚 Library Management System Database Project

📌 Project Overview

The Library Management System is a database management project developed using SQL. The project is designed to manage library operations efficiently, including managing books, members, addresses, and other library-related records. This project demonstrates the implementation of database concepts such as table creation, relationships, CRUD operations, and ER diagram design.

🎯 Objectives

• To design and implement a relational database for a library.
• To perform Create, Read, Update, and Delete (CRUD) operations.
• To establish relationships between tables using primary and foreign keys.
• To represent the database structure using an Entity Relationship (ER) Diagram.

🛠 Technologies Used

• SQL
• MySQL / MariaDB
• phpMyAdmin
• ER Diagram

📂 Project Features

• Database creation and management
• Multiple related tables
• Insert records into tables
• Retrieve data using SELECT queries
• Update existing records
• Delete records
• Table relationships using keys
• ER Diagram representation

📊 Database Components

The database includes tables for managing:

• Library records
• Member information
• Address information
• Related entities and relationships

CRUD Operations Implemented

Create

INSERT INTO table_name VALUES (...);

Read

SELECT * FROM table_name;

Update

UPDATE table_name
SET column_name = value
WHERE condition;

Delete

DELETE FROM table_name
WHERE condition;

Entity Relationship (ER) Diagram

The project includes an ER Diagram that illustrates the relationships between all database entities.

Learning Outcomes
