MongoDB is the most popular NoSQL database solution. However, SQL still dominates production projects, but interest in MongoDB has been growing for many years. Whether out of fashion or for a real technical solution to a problem for a web application, MongoDB now has many big customers and ambassadors. Therefore, MongoDB is a modern, powerful, user-friendly, lightweight database management system.
Do you want to excel MongoDB? If so, the MongoDB course can help you. You will get acquainted with this system and learn how to prescribe various commands in the course. Keep reading this article to learn about the MongoDB course. Let’s start with knowing what is MongoDB.
MongoDB is an object-oriented, dynamic, stable, scalable and SQL-free database system. Objects are stored in JSON format in separate documents. Instead of storing data in tables with values, we use a hierarchy and a JSON object system to create a more adaptive system.
The interest of MongoDB is to implement a high-performance system with perfect scalability. The system is extremely easy to install, it works under all operating systems, and there are libraries to handle it in all languages.
To learn this system, you can get comprehensive training in MongoDB.
The objectives of the MongoDB course are to:

MongoDB stores data in collections, which are similar to tables in a relational database. Each collection can contain multiple documents, which are the individual units of data in MongoDB. Documents are stored as BSON objects and can have different structures, with fields that can be of different data types.
Internally, MongoDB stores collections as files on disk, with each file corresponding to a namespace that includes the database name and collection name. Each document is stored as a BSON object within the file, with a unique identifier called an "_id" field.
MongoDB uses a flexible schema model that allows documents in the same collection to have different structures. This means that you can add or remove fields from a document without affecting other documents in the same collection. However, it's important to note that schema design is still an important consideration in MongoDB, and it's recommended to define a consistent schema across documents in the same collection to ensure optimal query performance.
MongoDB also supports advanced features such as indexing, replication, and sharding to optimize performance and scalability for larger datasets.
