MongoDB - As everyone know it's a document database that provides high performance, high availability, and easy scalability. Some people used Phone System. They might found this database on it. It's not difficult to deploy or test it. For Example: Deploy a Replica Set.
Anyway, I didn't write about how to deploy or use about it on this post. I wanted to talk about a book tittles MongoDB: The Definitive Guide, 2nd Edition Powerful and Scalable Data Storage By Kristina Chodorow.
A book was upgraded from a previous edition. It shows you the many advantages of using document-oriented databases, and good demonstrates. A book covers how to begin with MongoDB, how to install, perform and etc it. In a book, readers find 6 parts. Introduction to MongoDB, Designing Your Application, Replication, Sharding, Application Administration and Server Administrator.
After readers read a book. They are supposed to understand much more about a document-oriented database and how to install and perform with MongoDB. Concept in a book is very clear and it's easy to read and follow samples in a book. A book also gives idea for readers to use MongoDB and designing application.
However, A book has some errors about technical information and code in sample. Reader should use MongoDB doc for help during read and to find out more information.
