Library Management system Database queries

R
reshmajohney

The document describes the design of a database for a library management system. It includes the SQL queries used to: 1. Create tables for user login details, book details, book ratings, and user privileges. 2. Define primary keys, foreign keys, indexes and other attributes of the tables. 3. Insert sample data into the tables. 4. Provide examples of optimized queries on the login and book details tables.
