Database Design Project : Library Management System

In this video, I will teach you how to properly design a database through a real-life project example: Library Management System. This project involves the creation of a database that efficiently manages books, users, borrowing and returning, and other related information. We will start by identifying the entities and relationships in the system, followed by the creation of a data model and schema design. Through step-by-step instructions and explanations, you will learn how to design a robust and effective database that can handle the demands of a modern library. By the end of this video, you will have a solid understanding of the principles of database design and how to apply them to real-world scenarios.

Needs quiet a bit of improvement. In inventory table, is there is a need for inventory ID as a primary key. The table could have had the bookID and BranchID as composite primary key. This enforces to have an identifying relationship between inventory, branches and books. In your design, its a non-identifying reltaionship. Some of the relationships between tables are missing the multiplicity or relationship degree, these need to be stated at both ends of the relationship line. Some attributes like author, genre needs to have their own respective tables. A book can be written by more than one author and an author could have written multiple books. Same in the case of genres. Regarding the Table : Fine, It does not need the copyID as the attribute, it needs checkedoutID. Rationally thinking, in case of reporting or other metrics for business insights, a user could have checked out the same book multiple times. Based on your design, for audit purpose, I cannot determine when the fine was applied. The fine amount per day, could have changed over time. For Audits, need to track the fine amount against a checked out record. This would guarantee, a valid fine was calculated. In your design, you cannot track against the checked out details. It would be simpler to have the checkedOutID in the Fine table. With the checkedout ID, we can determine the copyID. If its too time consuming operation, we can denormalise the fine table and let it have the copyID.
