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:
The MongoDB training india provides an understanding of the basics of the MongoDB DBMS and methods for developing applications that store and process data based on it. The basic possibilities of saving, retrieving and searching documents (CRUD), and methods of generating search queries, including using the Aggregation Framework and Map/Reduce pipelines, are considered.
The course aims to teach the student to work effectively with MongoDB. As a result of the training, graduates can confidently work with MongoDB, create optimal queries, work with indexes, optimize, profile and update databases.
The course includes all the tools that can be useful to both the developer and the administrator: access control, backup, replication, logging, working with statistics, and scaling.
You can learn the following concepts in MongoDB training india:

Yes, MongoDB uses internal memory to cache frequently accessed data, indexes, and query results to improve performance and reduce disk I/O. MongoDB's default storage engine, WiredTiger, uses an internal cache to store frequently accessed data and indexes in memory. The WiredTiger cache is managed by the storage engine and can be configured to use a specific amount of memory. MongoDB also uses internal memory for sorting and aggregation operations. When executing a query that requires sorting or aggregation, MongoDB loads the relevant data into memory to perform the operation. The amount of memory used for sorting and aggregation operations depends on the size of the data being processed. In addition, MongoDB uses internal memory for write operations to improve durability and prevent data loss. When a write operation is received, MongoDB writes the operation to a write-ahead log (WAL) in memory before writing it to disk. This ensures that data is durable and not lost in the event of a system failure.
