Relational Database Design and Implementation: Clearly Explained, Fourth Edition, provides the conceptual and practical information necessary to develop a database design and management scheme that ensures data accuracy and user satisfaction while optimizing performance. Database systems underlie the large majority of business information systems. Most of those in use today are based on the relational data model, a way of representing data and data relationships using only two dimensional tables. This book covers relational database theory as well as providing a solid introduction to SQL, the international standard for the relational database data manipulation language. The book begins by reviewing basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL. Topics such as the relational data model, normalization, data entities, and Codds Rules (and why they are important) are covered clearly and concisely. In addition, the book looks at the impact of big data on relational databases and the option of using NoSQL databases for that purpose. Features updated and expanded coverage of SQL and new material on big data, cloud computing, and object relational databases Presents design approaches that ensure data accuracy and consistency and help boost performance Includes three case studies, each illustrating a different database design challenge Reviews the basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL Relational Database Design and Implementation: Clearly Explained

The book tries to provide a foundation but gets it conceptually and fundamentaly wrong. Namely, its definition of the relational data model, at page 90, and everything around it, does not even get the nomenclature, much less the concepts, right. It essentially uses SQL instead of relational nomenclature and concepts, together with entity relationship diagrams, and never explains correctly neither what are relations, and how they differ from SQL tables or ERD entities and relationships. Sad. Relational Database Design and Implementation: Clearly Explained When reading this book, I find that the author explains very simple concepts in an overly complicated way. Simple ideas like primary keys and foreign key relationships would take up several pages and have addenda upon addenda to the definitions and explanations. I found myself having to seek out other sources, such as Youtube and other books to explain the concepts easily, so I could build my understand of a foundational concept. The other problem with this book was the layout. Diagrams would be located several pages away from their explanation and important paragraphs would get interrupted by 2 3 pages of diagrams. Overall, I was very disappointed with having read this book for my class. After consulting other sources, I was in awe with the simplicity that they were able to explain the concepts Relational Database Design and Implementation: Clearly Explained This was our supplemental source in my database management course in university. The instructor gave us PDFs of the relevant chapters but I decided to purchase this outright since database management is what I want to pursue as a career.

This book has pretty much all you need as a beginner. Lots of useful examples, plain language, and concise writing makes this a valuable resource to keep on hand. Relational Database Design and Implementation: Clearly Explained Easy to read, very good foundation on databases.
