Learn MongoDB 4.x

By: Doug Bierer

Overview of this book

When it comes to managing a high volume of unstructured and non-relational datasets, MongoDB is the defacto database management system (DBMS) for DBAs and data architects. This updated book includes the latest release and covers every feature in MongoDB 4.x, while helping you get hands-on with building a MongoDB database app. You’ll get to grips with MongoDB 4.x concepts such as indexes, database design, data modeling, authentication, and aggregation. As you progress, you’ll cover tasks such as performing routine operations when developing a dynamic database-driven website. Using examples, you’ll learn how to work with queries and regular database operations. The book will not only guide you through design and implementation, but also help you monitor operations to achieve optimal performance and secure your MongoDB database systems. You’ll also be introduced to advanced techniques such as aggregation, map-reduce, complex queries, and generating ad hoc financial reports on the fly. Later, the book shows you how to work with multiple collections as well as embedded arrays and documents, before finally exploring key topics such as replication, sharding, and security using practical examples. By the end of this book, you’ll be well-versed with MongoDB 4.x and be able to perform development and administrative tasks associated with this NoSQL database.

In addition, a number of people have suffixes added to their names, such as Junior or III.  Furthermore, traditional companies might include a title such as Mr., Miss, Mrs., or Ms.

Bear in mind, however, that titles such as Miss. or Mrs. might also offend certain customers. Why? You might notice that the common formal title for a man is Mister, whereas for a woman it could be Miss or Missus. This means that the title gives away the marital status of a woman, but not for a man! Accordingly, the female title Ms. gained popularity, but this title might offend women who come from a more traditional culture!

Here is how the name structure appears for Book Someplace:

Name = {
"title" : <formal titles, e.g. Mr, Ms, Dr, etc.>,
