Overview of this book

MongoDB is the best platform for working with non-relational data and is considered to be the smartest tool for organizing data in line with business needs. The recently released MongoDB 4.x supports ACID transactions and makes the technology an asset for enterprises across the IT and fintech sectors. This book provides expertise in advanced and niche areas of managing databases (such as modeling and querying databases) along with various administration techniques in MongoDB, thereby helping you become a successful MongoDB expert. The book helps you understand how the newly added capabilities function with the help of some interesting examples and large datasets. You will dive deeper into niche areas such as high-performance configurations, optimizing SQL statements, configuring large-scale sharded clusters, and many more. You will also master best practices in overcoming database failover, and master recovery and backup procedures for database security. By the end of the book, you will have gained a practical understanding of administering database applications both on premises and on the cloud; you will also be able to scale database applications across all servers.

MongoDB CRUD Operations

In this chapter, we will learn how to use the mongo shell for database administration operations. Starting with simple create, read, update, and delete (CRUD) operations, we will master scripting from the shell. We will also learn how to write MapReduce scripts from the shell and contrast them to the aggregation framework, into which we will dive deeper in Chapter 6, Aggregation. Finally, we will explore authentication and authorization using the MongoDB community and its paid counterpart, the Enterprise Edition.

In this chapter we will cover the following topics:

    • CRUD using the shell
    • Administration
    • Aggregation framework
    • Securing the shell
    • Authentication with MongoDB
