Advanced Querying
In the previous chapter, we learned how to use MongoDB for auditing and the difference in semantics between logging and auditing. In this chapter, we will dive deeper into using MongoDB with drivers and popular frameworks from Ruby, Python, and Hypertext Preprocessor (PHP).
We will also show the best practices for using these languages, and the variety of comparison and update operators that MongoDB supports at the database level, all of which can be accessed via Ruby, Python, and PHP.
Finally, we will learn about change streams, a MongoDB feature that we can use to stream database changes to our application in real time.
In this chapter, we will cover the following topics:
- MongoDB CRUD operations
- Change streams
