Build a database for a public library to analyze

This assignment involves creating a database for a public library to collect and analyze information about clients' reading interests, focusing on books and client preferences. You are required to create database tables based on an ER diagram, populate these tables with provided sample data, and write SQL queries to retrieve specific information to support library management decisions. Tasks include defining primary and foreign keys, establishing relationships among tables, creating indexes for query optimization, and creating views to simplify data analysis. Detailed reporting of your SQL code with comments explaining each step is mandatory.

The essential goal of this project is to design and implement a relational database system that effectively models a public library’s book borrowing activities and client interests. To accomplish this, the first step involves translating the conceptual ER diagram into a logical schema, which encompasses creating tables, primary keys, foreign key relationships, and indexes optimized for query performance. The next phase involves populating these tables with the provided sample data, ensuring data integrity and correctness.

The core logic begins with the creation of four principal tables: Author, Book, Client, and Borrower, each with proper constraints to ensure referential integrity. The Author table stores individual author details, including nationality. The Book table captures book-specific information, linking each book to a single author, consistent with the assumption that each book has one author. The Client table records personal details for each library client, including date of birth and occupation. The Borrower table logs the borrowing activity, connecting clients to books and the specific borrow date.

Creating the tables involves careful consideration of data types, constraints, and relationships. For example, the AuthorID in the Author table serves as the primary key, while BookID in the Book table is the primary key and includes a foreign key to AuthorID to establish the author-book relationship. Similarly, ClientID links clients to their borrowing records via BorrowID, with foreign keys maintaining referential integrity. Indexes are explicitly created on columns frequently used in queries, such as BorrowDate, BookGenre, and ClientAge, to improve query speed.

Data population is performed by executing INSERT statements, inserting sample records into each table as provided. This step is crucial for realistic testing of query performance and correctness.

The subsequent phase involves writing SQL queries to answer specific informational questions. These include retrieving all client information, extracting client names based on borrowing dates, identifying top authors, least borrowed authors during specified years, most borrowed books, popular genres, and demographics-based insights like age groups and occupations. Additionally, creating a view to display titles borrowed by at least 20% of clients helps in summarizing significant borrowing patterns.

Each query is carefully crafted with comments explaining its purpose and logic, often utilizing SQL features like JOINs, GROUP BY, ORDER BY, and aggregate functions. Indexes are recommended and created on columns involved in WHERE clauses, JOIN conditions, and ordering to enhance performance. The final step involves assembling all SQL statements, including table definitions, data insertion, query commands, and index creation, into a plain-text file for submission.

In conclusion, this project demonstrates comprehensive application of advanced SQL features to design a functional, efficient, and insightful database system for a public library, enabling data-driven decision-making for future acquisitions and management strategies.
