MongoDB in Action: Covers MongoDB version 3.0

I've really enjoyed this book. My favorite part by far is the tech comparison in the early chapters. The authors go over the pros and cons of MongoDB and describe the use cases for it, and it's competitors. The examples are all in Ruby, but are readable (even for a JS dev). I was up and running in ~5 minutes and followed along in each chapter. At about 1/3 of the way in, I felt I had a firm enough grasp to be able to implement it into my own project.Coming from a relational (MySQL) background, the concept of a NoSQL DB was intriguing but took a bit of getting used to ("you don't have to design your schema up front?"). Storing and receiving data in a JSON-based format felt right at home after working with web frameworks and this book provides some great samples.

Very good

Great read, but I am a MongoDB novice. I have not finished the book, but what I have read has helped move me forward with my MongoDB project.

Great book for developers and database administrators as well. I really like the way the book it's organized.

Good book to start learning about MongoDB

This updated edition is aimed at software developers, but it doesn't ignore those of us who are more "casual" users of MongoDB. Indeed, this is an excellent book for newcomers to MongoDB, especially if you are patient and willing to read through an introductory chapter focusing on "MongoDB's history, design goals, and application use cases." Many people, of course, just want to jump straight into downloading software, running it, and playing with it for a while before getting down to serious stuff such as application use cases. So Appendix A is the place to go for getting MongoDB onto Linux, Mac, or Windows PCs. Then, once you have MongoDB installed, you can jump back to Chapter 2 to start learning how to use the JavaScript shell. After that, things start getting more "practical." For example, Chapter 3 introduces "Writing programs using MongoDB." Here, Ruby is used to work with the MongoDB API, but the author notes: "MongoDB, Inc. provides officially supported, Apache-licensed MongoDB drivers for all of the most popular programming languages. The driver examples in the book use Ruby, but the principles we’ll illustrate are universal and easily transferable to other drivers. Throughout the book we’ll illustrate most commands with the JavaScript shell, but examples of using MongoDB from within an application will be in Ruby."I won't try to sum up everything in this well-written, 13-chapter book. I have used older, 2.X versions of MongoDB in MEAN stack applications. And, separately, I have worked a bit with Ruby and MongoDB. But in each case, I haven't needed to learn all that much about MongoDB itself, mainly just ensure that it is storing data that can be accessed in the right place and updated, saved or deleted as needed. So this book, written for 3.0.X (and later, as well as earlier) MongoDB releases is an eye-opener for me and one that I will keep around for reference and more learning now that I have upgraded to 3.2.Part 1 of this 2nd edition "provides a broad, practical introduction to MongoDB." Part 2 offers "a deep exploration of MongoDB’s document data model." And Part 3 examines MongoDB "from the database administrator’s perspective. This means we’ll cover all the things you need to know about performance, deployments, fault tolerance, and scalability."One cautionary note: The author points out that "as of MongoDB v3.0, 32-bit binaries will no longer be supported." Of course, some 3.X 32-bit binaries are still out there, and you can install them, but you will get a lot of warning messages from MongoDB. Download a 64-bit binary if your system will support it.The author realizes that many readers who have some MongoDB experience will not read the book straight through but will jump around to chapters in many different orders and will even skip some chapters. And this is okay. MongoDB in Action: Second Editon is a book many of us will be happy to have handy whenever we need to get a better grip on some new aspect of working with this great open-source, document database.(My thanks to Manning for providing a review copy.)

Excellent read and details concepts in granular details

E' veramente un ottimo libro: i dettagli di mongodb vengono presi e spiegati con dovizia di particolari. Anche se non si conosce nulla di questo database, gli autori accompagnano il lettore dalle basi fino all'utilizzo più avanzato. Utile anche il confronto continuo con i database relazionali (si presuppone che chi acquista questo libro abbia almeno le basi sul mondo dei database). Tratta in modo approfondito anche la configurazione dei cluster e dello sharding (anche se in quest'ultimo caso sono state fatte delle modifiche dalla versione 3.* di mongodb e la configurazione è leggermente differente).I difetti di questo libro? Gli esempi avanzati sono fatti in Ruby (un capitolo intero è dedicato ad un esempio avanzato con questo linguaggio - IMHO: non potevano scegliere tecnologie come nodejs più vicine al mondo di MongoDb?). Inoltre, questa nuova edizione si basa sulla versione 3.0 di mongodb quando siamo alla versione 3.5. Questo comporta che ci sono molte mancanze soprattutto a riguardato le aggregation; un capitolo intero è dedicato a questo argomento, ed è un bene leggerlo per farsi un'idea, ma sono così tante le novità introdotte che è meglio rivolgersi subito dopo alla documentazione ufficiale - per esempio, dalla versione 3.2 è stato introdotto il comando $lookup che permette le join tra collection in modo facile.Ben fatti i capitoli riguardanti il text serch e gli index... molto dettagliati quelli che descrivono la configurazione del replica-set e lo sharding.Consigliato.

Il prodotto ha soddisfatto pienamente le mie aspettative

I started reading the book as a complete novice in NoSQL and MongoDB in particular. It helped me understand how to efficiently set up and query a MongoDB, to great results. I really have a sense of gratitude to the authors.

Avec quelques bases en Json et en bases de données plutôt relationnelles j'ai facilement pris le livre en main. Le contenu est facile à lire et les exemples sont clairs (il faut avoir des notions d'anglais). Le livre suit une progression que je trouve bien adaptée, même si je n'ai pas encore attaqué les derniers chapitres.Je ne sais pas si le livre couvre tout le potentiel de MongoDB mais il me semble qu'il fournit tous les outils pour produire des bases de données bien structurées et optimisées.
