Author Description

Relational database design is one of the most vital tasks in software development. Every application relies on a well-structured database, and errors made during the design stage can cascade into performance issues, unreliable data, and hard-to-maintain systems. This book tackles those challenges directly by presenting a clear and practical six-step method for accurately modeling user data to create robust, secure, and dependable relational databases. This third edition of Six-Step Relational Database Design bridges the gap between theory and implementation. It offers a simple, structured, and reliable technique for designing relational databases that are easy to understand and suitable for implementation on any relational database management system (RDBMS). Beginning with a clear client problem statement, the process walks through six logical steps that lead to a complete and accurate Crow’s Foot Relational Model, ready for implementation. Designed for both students and professionals, the book is a hands-on guide to creating relational data models that meet real-world requirements. Students can apply the method in academic projects, while developers can use it to build or improve production-ready databases. The six-step technique is also ideal for validating and refining AI-generated database designs, ensuring that automated tools produce high-quality outcomes. This edition retains the proven six-step approach from the second edition but introduces a key enhancement: the inclusion of basic inline CRUD (Create, Read, Update, Delete) auditing. Readers learn how to embed auditing attributes such as CreatedBy, CreatedOn, LastUpdatedBy, LastUpdatedOn, IsDeleted, DeletedBy, and DeletedOn into key tables. This supports greater accountability, transparency, and compliance with industry standards, and equips developers to meet modern demands for traceable and secure data systems. The book includes three real-world case study scenarios that are used throughou
