MongoDB is a popular NoSQL database that has been around for over a decade. It‘s a document–oriented database, meaning that it stores data in documents rather than in traditional rows and columns. It‘s open–source and provides high scalability, availability, and performance.

MongoDB uses a document–oriented data model, which means that documents are stored in collections. These documents are essentially JSON–like structures that contain key–value pairs. A single document can contain multiple fields and subdocuments, and the data structure can vary from document to document. This allows for a much more flexible data model than traditional relational databases.

One of the main advantages of MongoDB is that it is highly scalable. It can easily scale up or down depending on the size of your data set. MongoDB also provides sharding, which allows you to partition the data across multiple servers. This helps you manage large data sets efficiently.

MongoDB also provides a rich query language that allows you to perform complex operations on your data. It also provides an aggregation framework for analyzing data and creating reports.

MongoDB also provides high availability. It is designed to be highly available, meaning that it can continue to operate even if one
