Summary
In this chapter, we went through basic MongoDB topics such as major MongoDB processes, how they work, and why they exist.
We learned that MongoDB consists of some main components such as core, import and export, GridFS, and diagnostic tools. Then, we discussed the basic processes that make MongoDB work, that is, mongod and mongos. Also, we learned that developers or system administrators can manage MongoDB using the mongo process. This is an interactive JavaScript shell, which enables developers to run and execute commands, queries, and administration procedures.
Next, we talked about import and export tools that give developers the ability to export and import objects from and into the database, which is used for backup and restoration procedures. In addition, you can find a brief description of the GridFS components and diagnostic tools that are required to work with the filesystem. We also learned how to find database statistics and issues with diagnostic tools.
In the next chapter, we will learn about the causes of failure in MongoDB and find remedies and solutions to overcome these problems.
