First off, this book is well-written. Mr. Hernandez does a good job of explaining the "why" behind his explanations. He also provides tips that just seem to make sense. He advises that a table have a name that is plural, because each record is one "instance" of the data related to the table. As an example, a table called CarColors would have several rows, each containing one car color.My only real criticisms are:1. That he did not go enough into effectively indexing, applying primary/foreign keys, and applying constraints.2. There was not enough discussion of the various "normalized" forms, when they should be used, and so forth. This is covered in a "flyover" manner that makes sense, but perhaps a more "in-depth" discussion of normalized forms is beyond the scope of the book.I felt like I knew most of the information, but I didn't feel this book was a waste of money, as many of his "common sense" approaches I will utilize in my own DB designs in the future.
Thus far I see no difference between this and the 2nd Edition, so if you already have that version you don't need this one. That being said, it doesn't make this edition any less deserving of five stars. My professor, a full time Software Architect, recommended this book to me four years ago. Now, as a successful Software Developer, I'm recommending it as well. Based on my experience, this book covers everything one needs to know about database design.
I found this book very thorough at an introductory level and well written. I think someone with no database experience at all could read this and help with database design. The only criticism I have is the verbosity. Some things are repeated or can be assumed.This book does not get into normalization or any details, which I liked.
I like that book. It was easy to read, unfortunately there is to much of copy paste. I would rate it 5 stars if book took just 300 pages, seriously there is not much in order to make 600 pages. But approach brought by author is interesting, anyway I would like to ask the question. How good does this approach fit at 2018 with agile, scrum? I am not sure that I'll get back to read this book one more time, which is really important sign for me, maybe because it is easy book. What I don't like very much, author mention that competitor authors don't know something, well...
This book provides the basic concepts for good relational database design. It is structured in a very easy to read format. It clearly walks you thought design objectives and defining tables, keys, fields, table relationships, as well as business rules. Chapter 14 is an interesting chapter titled "Bad Design - What Not to Do".
I wish more technical primers were written like this. All new terms are clearly explained.
No, this is not the book for you if you have extensive experience in software design and have already absorbed the basic concepts of database design by osmosis.This is a book for "mere mortals," just like it says. I'm a reasonably smart, reasonably well-educated person who had some computer experience, but didn't even really know what a relational database was. Through circumstances too odd to mention, I was given primary responsibility for designing a commercial web application.I read this book cover to cover, and designed the database that became the core of the product. The product actually works, and seems to be selling. Later in the development cycle, I worked with a brilliant MIT-trained software engineer, and he found my basic db design just ducky.I definitely owe Mr. Hernandez a beer. Figured writing this review was a reasonable substitute.
Michael Hernandez does a great job of explaining how the relational model works, and how a database should be designed from start to finish. Most of us will probably not follow his advice, though.If you do decide to follow his advice, then be prepared for a very lengthy trip when designing your DBs. I tried on my first DB and found that the company I was designing the DB for started to get slightly irritated. This is because in this book Michael suggests you have a full blown manager and or user meeting with virtually every single change you make (also meetings for requirements, ideas, characteristic identification, user input meetings, manager meetings... oh look, a change happened, now we have to go through all of the same meetings again... and again... and... >yawn<... every other page in this book suggests another meeting). I must have had 25-30 meetings total, which just isn't necessary. Also, there is all sorts of spec sheets you should fill out for every single aspect of the database. I would probably just use a modeling tool (such as Visio) instead of going through this daunting task (I would have had to fill out over 300 spec sheets just for the fields!... it was a big DB)Although his way of designing is probably the way you should really go, I found that designing a sound database doesn't require quite so much work. You can do most of the design process if you have a good modeling tool, which is what I ended up doing and my DB turned out quite well (you still should conduct meetings, but not for every single aspect of the database... your clients will begin to think you have no idea what you're doing). However, this book pounds the relational design in your head so much, that you can't help but get over the tough learning curve of how a relational database really should be designed.
