Book Review: Database Design for Mere Mortals

A Hands-On Guide to Relational Database Design (3rd Edition)

This book is THE book for the database beginner. It thoroughly covers design principles and process, and it covers them in depth.

The book is broken into four parts, Part I: Relational Database Design, Part II: The Design Process, Part III: Other Database Design Issues, and Part IV: Appendixes.

Part I starts with a chapter that gives the history of databases and the path we took to get where we are. It continues with a chapter that covers the reason to have a good design methodology and what the goal of the methodology should be.

Chapter three is really cool for those just getting into database design. It introduces some of the most common terminology used in the database design process. It is not just a glossary (which this book also has after the appendixes), it goes much further than just a definition and includes diagrams to help with the explanations.

Part II covers the database design process. Topics the author covers include table structures, field specifications, assigning primary keys, table relationships, views, and levels of data integrity.

Part III covers bad design and when bending the rules of proper design are ok.

The appendices (Part IV) include a summary of design guidelines, example form templates, diagram symbols, a check list of design guidelines, and an activity diagram (flowchart) of the database design process.

I have listed each part and the chapters they contain below.

Part I. Relational Database Design
1. The Relational Database
2. Design Objectives
3. Terminology

9. Field Specifications
10. Table Relationships
11. Business Rules

15. Bending or Breaking the Rules

Part IV. Appendixes
A. Answers to Review Questions
B. Diagram of the Database Design Process
C. Design Guidelines
D. Documentation Forms
E. Database Design Diagram Symbols
F. Sample Designs
G. On Normalization
H. Recommended Reading

One thing this book does not include is coverage of the structured query language bracket (SQL). This book is purely about designing the database not about what to do with the data once it is in the database. That's not a downfall of the book, it actually makes it better. The author is able to focus on design principles and drill much further into them by excluding teaching SQL.

Overall I found the author's writing made reading the book a pleasant experience. I cannot say that for all database books I have read. Another reason it is good is that the author goes into extreme detail on each topic he covers.

The author also has made the forms he uses in the book available in Word and PDF format for download on the publisher's web site

All in all I highly recommend this book to database beginners. It will teach you how to do things the right way from the get-go.

I also recommend it for the non-DBA developer who is tasked with creating databases on their projects because the project can't afford a real DBA. There are a lot of those out there and I have seen them be the cause of many painful projects that have to manipulate good code into bad code to compensate for poor database design.

In the midst of the widespread popularity and adoption of cloud computing, it seems like everything is being offered “as a Service” these days: Infrastructure? Check. Platform? You bet. Software? Absolutely. Toaster? It’s only a matter of time.

In his session at 16th Cloud Expo, Kevin Hazard, Director of Digital Content for SoftL...

Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...
For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...
Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...
Our guest on the podcast this week is Jason Bloomberg, President at Intellyx. When we build services we want them to be lightweight, stateless and scalable while doing one thing really well. In today's cloud world, we're revisiting what to takes to make a good service in the first place. Listen in to learn why following "the book" doesn't necessarily mean that you're solving key business problems.
Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...
Microservices, for the uninitiated, are essentially the decomposition of applications into multiple services. This decomposition is often based on functional lines, with related functions being grouped together into a service. While this may sound a like SOA, it really isn't, especially given that SOA was an object-centered methodology that focused on creating services around "nouns" like customer and product. Microservices, while certainly capable of being noun-based, are just as likely to be v...

An explosive combination of technology trends will be where ‘microservices’ and the IoT Internet of Things intersect, a concept we can describe by comparing it with a previous theme, the ‘X Internet.' The idea of using small self-contained application components has been popular since XML Web services began and a distributed computing future of smart fridges and kettles was imagined long back in the early Internet years.
