Kristina is lead maintainer for the MongoDB PHP and Perl drivers. She wrote the official PHP driver and manages the PECL and CPAN releases. She currently works as a software engineer for 10gen in New York City and gives talks at meetups and conferences around the world. Mike Dirolf is a Software Engineer at 10gen, where he works on the MongoDB project. He mainly works on client drivers for Python and Ruby, but also takes time out to talk about MongoDB - he has presented at EuroPython, Strange Loop Conf, RubyEnRails, RuPy and RubyConf as well as at meetup groups in New York City, London, Washington D.C. and San Francisco. Mike received a B.S.E. in Computer Science from Princeton University. Born in Albany NY, Mike currently resides in New York City.

Sehr geschätzt habe ich bei der Lektüre, dass das Buch nur knapp 200 Seiten umfasst und dadurch alles schnell auf den Punkt gebracht wird.
Man kann es deshalb gut von vorne bis hinten lesen, wobei es sich zum Nachschlagen ebenso gut eignet, dank des guten Inhaltsverzeichnisses und Indexes.
Der Start mit MongoDB geht sehr schnell, macht Spaß, aber verleitet. Ich denke, die Gefahr liegt darin, dass man bei der Implementierung von Datenbanken mit MongoDB schwerwiegende Fehler machen kann. Das trifft auf das "Schema-Design" zu, auf die Auswahl der richtigen Indizes und natürlich auf die Architektur, wenn man auf hohe Skalierbarkeit bedacht ist (Replication, Sharding). Deshalb sollte man diesen "Definitive Guide" wirklich sehr aufmerksam lesen, bevor man sich als weniger Erfahrener an MongoDB heranmacht. Wird sich sicher lohnen...

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.
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.
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.
* 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.
If you're coming from a relational database background and wish to learn more about MongoDB or are interested
in it as an example of a NoSQL implementation, this is a great book. I enjoyed reading it and learned quite a bit
in the process. Read below for the full review.
I'm coming from a traditional relational database background, specializing in MySQL over the last 7 years. I was hoping
that this book would be a good introduction to NoSQL in general as well as how to use MongoDB specifically.
It turned out to be all that I was hoping for and more. It's very easy to read and the material is very easy to
grasp. If you're coming from MySQL, things will feel familiar from the get go. For example, I installed mongodb
on Ubuntu 10.10 using apt (version 1.4.4 of mongod) and the default config file was /etc/mongodb.conf and the
So, all I needed to do was apt-get install mongodb and I had mongodb installed, up and running. I used this quick
install to play with as I read through the book. The book was full of clear and concise examples that I could use
to easily play around with MongoDB and get a feel for using it.
The layout of the book was very good in that the chapters cover the basics while the book still contains the more
detailed information in the Appendixes. I liked this separation of material, a separation of the "book" and the
"reference material" if you will.
In the end, I'm not sure how big a fan I am of MongoDB itself, but I'm a big fan of this book. I had an installation
of MongoDB up and running that I could configure, administer and query. All of this and nothing seemed
difficult or confusing. It was exactly what I was hoping for.
Some chapters I have looked at:
1) explains why use MongoDB and how it helps application programmer do data storage and forget about shar'ding, and save the cost of buying expensive ultra high capacity hard disk and just add cheap generic server when there is a need to scale up the data storage space.
2) a chapter to give introduction to aggregates, including Map/Reduce, and explain Map/Reduce can be slow and may be best suited to do the calculations, save the data into a permanent collection, and re-use the data, instead of doing Map/Reduce real time.
3) a chapter that gives 4 real application usage of MongoDB, using drivers for Java, Ruby, PHP, and Python. One example talks about using MongoDB to store real time Analytics data.
The book is written by two employees who work for the company which created MongoDB, so the book does have authoritative voice. It is one of the Definitive Guides from O'Reilly that I find fairly well written and enjoyable to read.
