Not Good Enough
25 settembre 2011
Di Nick de Plume

Formato:Brossura|Acquisto verificato Amazon
For each product out there, there is a must-have book associated with it. This is not the one for MongoDB.
First let's talk about coverage: The author has written a total of 3 books under the MonogDB label, all under O'Reilly:, this one with 200 pages, the "tips" one with 66 pages(!) and the "scaling" one which is even slimmer at 60 pages!!), and each single one with a price tag of ~US$30. The total page count doesn't make this division necessary. Why not aggregate all this writing into a single volume?
I don't believe this book is very useful if you are a developer and you are looking to adopt a NoSQL DB. This book lacks in all the places a definitive guide should deliver. After quickly reading it in one session (it's very slim), I still felt "hungry" to learn more about the product. There isn't much more covered in those pages than what's available online for free. The example material in various programming languages, occupying a third of the book, shouldn't even be printed. That's what a link to a website, accessible to readers who invested in a hard or digital copy, is for. The rest of the contents goes about NoSQL as much as you can read from the MongoDB org or what a good ol' Google search will return by querying these keywords.
My closing note to the publisher: pack the content of those 3 books you've got from the same author inside one single book and call it "A introduction guide to MongoDB". Continue to sell it for the same price tag as of a single volume. I'll rate this one higher.
My closing note to the author: I believe there is still a need to write a real definitive guide for this technology. It should contain much more details than what you've written up so far. A brief search on forums suffices to show you what areas need to be expanded. MongoDB is new and a definitive guide is what it needs for becoming more adopted.

A good intro and reference

As an RDBMS practitioner (MSSQL, PostgreSQL), I was interested in coming up to speed with some of these new alternative data stores. I chose MongoDB initially due the "look and feel" of it's site, documentation, and community. After watching an O'Reilly webcast, I was interested enough to purchase the book.
At around 200 pages, it is concise enough to read cover to cover - something I rarely do with tech books, often preferring to use the longer ones as a reference. The introduction does an excellent job of introducing the concepts behind MongoDB, bridging them to the relational database concepts I already know. It goes into explaining the pros and cons of "No(tOnly)SQL" engines, and mentions some of the datatype "gotchas" one needs to be aware of in using the JavaScript shell, which would not be obvious to one used to using SQL to directly query an engine instead of the JavaScript interface in the Mongo shell.
In subsequent chapters, implementation, administration, and development concepts are covered. There is also a brief internals section that may help the traditional database user understand the inner workings of the MongoDB engine.
It is an enjoyable read, and I expect that this book will continue to be a useful reference after the initial read through, as my experimentation with MongoDB continues.

Not definitive, not much for developers, and THIN!

This certainly isn't a definitive guide for MongoDB. It's a high-level intro.
It hits most of the important points to understanding Mongo capabilities and design. And it's organized in a more intelligent manner than the online Mongo DOCS. OK so far. But this book is still very reliant on on the mongo command line tool for examples. For most useful purposes, the command line is just a quick teaching tool -- aside from admin tasks, you're not really using Mongo as a database until you're writing client applications with the drivers.
Other thoughts:
* I knew this book was lacking when I looked for "write_concern", "slaveOK", and "thread"/"thread safe" in the index and found nothing
* The discussion of getLastError, and error-handling in general is weak...this is an important topic for deciding on the performance/reliability/function of a real MongoDB client application and coding it accordingly
* As much as I want to better understand the various Mongo drivers described online at api<dot>mongodb<dot>org, there's not much complementary info in this book
I know, I know, Mongo is new. I just wish there were something better for quenching the thirst for power that developers have. And I know there are 10+ languages for the drivers, but in the interest of seeing deeper instruction, I'd rather see a focus on ONE language (Java might be best for most, even if a developer is working with something else...they will know Java).
Still, I believe MongoDB will be the noSQL database standard. Maybe I'll try another book.
