OReilly MongoDB and Python mobi format


I’ve been building production database-driven applications for about 10 years. I’ve worked with most of the usual relational databases (MSSQL Server, MySQL, PostgreSQL ) and with some very interesting nonrelational databases (Freebase.com’s Graphd/MQL, Berkeley DB, MongoDB). MongoDB is at this point the system I enjoy working with the most, and choose for most projects. It sits somewhere at a crossroads between the performance and pragmatism of a relational system and the flexibility and expressiveness of a semantic web database. It has been central to my success in building some quite complicated systems in a short period of time. I hope that after reading this book you will find MongoDB to be a pleasant database to work with, and one which doesn’t get in the way between you and the application you wish to build.
