About this ebook

MongoDB is a high-performance and feature-rich Document Orientated Database. This popular, highly scalableNoSQL database is used to power some of the world's most used applications and websites.

MongoDB Starter is designed to get you working with MongoDB as quickly as possible. Starting with the installation and setup, we quickly show you how to start importing your data into the database. Furthermore, you will learn about CRUD operations in MongoDB, its Map Reduce support, schema design, and performance tuning operations.

After successfully installing and setting up MongoDB, you will be introduced to important configuration parameters and the terminologies used in the Mongo world and their equivalent in the relational world. You will learn how to import data into the database and connect to the MongoDB from the Mongo shell and execute some queries. We will then move on to advanced topics such as performing insert, update and upsert(update + insert) operations, executing advanced queries, schema design concepts, and creating indexes for performance. MongoDB Starter finishes with a look at the new aggregation framework, Map Reduce operations, and how to bulk import and export data.

    About the Author

    Amol Nayak has been working in the Java/JEE space for the past seven years and is currently employed at a leading investment bank where he is working on cutting edge technologies, predominantly open source. He is playing around with MongoDB by developing prototypes for various use cases at his workplace. He is an open source enthusiast and supports it by contributing to the open source frameworks and promoting them.

He has also made contributions to the Spring Data Mongo project.

    I would like to thank everyone at Packt who has been involved with this book. It all started when Ashish from Packt approached me to author a starter book in Mongo. I would like to thank him for giving me this opportunity. It has an excellent experience full of learning along the way. Being my first title, I struggled initially with the process of writing and submitting the content. If it hadn't been for Suraj, Sruthi, and Yogesh from Packt, I wouldn't have been able to deliver the content on time. Suraj and Sruthi showed great patience and helped me a great deal in formatting and organizing the content that I submitted.

    A special thanks to Varad Meru, the technical reviewer of the book who agreed to review the contents at very short notice. If it hadn't been for him, who reviewed the content till late at night, we wouldn't have been in a position to go ahead with the publishing of the title on time. I would like to thank the technical editor, Pragati for her exceptionally quick turnaround time which helped get the book ahead into production in no time.

    Finally I would like to thank the other staff from Packt who were involved in the book's publishing process but haven't interacted with me, my office colleagues who supported me a great deal, friends, and my mom, who I wasn't able to devote much time to owing to the schedules for the delivery of the content of the book.
