This document describes a library management system that uses a relational database to store and manage library data. It discusses using SQL and Microsoft Access to create tables, define relationships between tables using primary and foreign keys, and insert and manipulate data. Sample entity relationship diagrams and database tables are shown for books, customers, branches, book issues and returns. The system aims to computerize the library's operations and provide a more effective way to manage library resources and user accounts than a manual paper-based system.
