Data Modeling Essentials, Third Edition, covers the basics of data modeling while focusing on developing a facility in techniques, rather than a simple familiarization with "the rules". In order to enable students to apply the basics of data modeling to real models, the book addresses the realities of developing systems in real-world situations by assessing the merits of a variety of possible solutions as well as using language and diagramming methods that represent industry practice.
This revised edition has been given significantly expanded coverage and reorganized for greater reader comprehension even as it retains its distinctive hallmarks of readability and usefulness. Beginning with the basics, the book provides a thorough grounding in theory before guiding the reader through the various stages of applied data modeling and database design. Later chapters address advanced subjects, including business rules, data warehousing, enterprise-wide modeling and data management. It includes an entirely new section discussing the development of logical and physical modeling, along with new material describing a powerful technique for model verification. It also provides an excellent resource for additional lectures and exercises.
This text is the ideal reference for data modelers, data architects, database designers, DBAs, and systems analysts, as well as undergraduate and graduate-level students looking for a real-world perspective.

Part one addresses the basics in data modeling. The need for modeling when designing databases is explained and alternative modeling approaches such as ER and UML discussed. The ER approach is the one developed in detail. Usual data modeling concepts such as Classes, Generalization, Specialization, Attributes, Relationships, Normalization, etc. are introduced and explained here.
The chapter on primary keys discusses the different candidates for key selection and provides valuable guidelines for choosing them. A short chapter on extensions and alternatives to the ER approach, in which the UML notation is addressed, ends part one.
Part two is about the organization of the data modeling task and the data modeling cycle, from the requirements phase to the conceptual, then to the logical data models. Each phase is developed in detail and illustrated through sensibly chosen examples. Thorough pro and con argumentation is provided. How data modeling fits in the project perspective, the role of different actors involved - the business specialist, the data modeler, the database designer, etc. - and project organization matters are addressed too.
Part three addresses advanced normalization - BCNF, 4NF and 5NF - in terms that are as simple and accessible as reasonably possible, compared to other data modeling books that pretend achieving the same level of completeness. Modeling of time-dependent data and business rules, barely avoidable in real-life databases, is also covered.
A short chapter of 21 pages on data warehouses and data marts addresses OLAP data modeling. That's plenty, as the book mainly focuses on OLTP data modeling. Another short chapter whose purpose is to provide a quick overview of enterprise data modeling and of data management aspects in general ends the book.
This is a well-written, well-illustrated and complete book that I liked very much. I highly recommend it. Without doubt, it's an outstanding book written by capable and rigorous authors.
It's also a thick and dense book that beginners should precede by shorter, introductory readings.
I was afraid that Hadoop and NoSQL killed OLTP and OLAP data modelling, but it seems many startups have created a real mess data model wise and that data modelling as a discipline is making a comeback. Poor data models lead to excessive hacks and patchwork code.
The book is logically put together, and has a very detailed contents index, which makes finding relevant information easy. The sections I have read not only explain the theory but also give good examples putting the theory into practice. However, they sometimes seem to place too much emphasis on a theoretical approach that would never be used in the real world.
Overall I find this book very useful and have marked it up with sticky notes for sections I'll revisit for my next database modeling design.
One supposes that such a mixed bag of goods results from two writers attempting together to produce a common message. In this case, that attempt fails. And what we see instead are two markedly different forms of outreach and instruction. I didn't care to discover which author wrote which section. But the results were obvious. It is up, in my view, to the authors and the editors to sort this out in hopes of producing a better quality result in the future.
We would recommend the book, in a qualified sense, to the practictioner. The excellence does outweigh, and prevail over, the mediocrity, even though it is, at times, a "close run thing", as someone famously said. And we would hope also that the authors and editors would take these candid comments to heart. God bless.
