How Does MongoDB works & its Features?

 

MongoDB is a modern, open-source, document-based, distributed database management system that can be used for a wide range of purposes. It was made by MongoDB Inc., which also distributes and supports it. It is a powerful, flexible, and agile NoSQL (non-relational) document database that stores data in documents that are similar to JSON (JavaScript Object Notation) objects. MongoDB can be used with Linux, Windows, and macOS.

It comes with a full set of tools that make it easy to manage data. It is built for modern application development and the cloud, and developers, data analysts, and data scientists are the ones who should use it.

There are two versions of MongoDB: MongoDB Community Server, which is open source and free to use, and MongoDB Enterprise Server, which comes with a MongoDB Enterprise Advanced subscription.

How does MongoDB works?

MongoDB is set up with a client-server model, in which a server daemon connects to clients and handles their database actions. For clients to connect and use databases, the server must be running.

MongoDB is different from other databases in how it stores data. In MongoDB, a record is a document, which is a data structure made up of field and value pairs, like JSON objects. Documents are stored in collections (analogous to tables in RDBMS).

MongoDB's most important Features

Here are some of the most important things about MongoDB.

• Views that can only be read are possible with MongoDB. It also lets you use arrays and nested objects as values, which lets you make schemas that are flexible and changeable. It also works with multiple storage engines and gives you an API that you can use to build your own storage engines.
• MongoDB is made to work quickly and keep data for a long time. It has built-in data models that reduce the amount of I/O on the database system. Also, its indexes make queries faster and, more importantly, they can include keys from documents and arrays that are embedded.
• It comes with a rich and powerful query language that supports read and write operations, data aggregation, and other modern use cases like text search, graph search, and Geospatial queries.
• It has the power of relational databases because it supports full ACID transactions, joins in queries, and two types of relationships instead of just one: reference and embedded.
• MongoDB also has high availability, which it achieves with a feature called "replica set" (a group of MongoDB servers that maintain the data set thus providing automatic failover, data redundancy, and availability). There is also support for horizontal scalability, in which data is spread across a cluster of MongoDB servers using sharding.
• MongoDB has many security features, such as authentication and authorization, access control, TLS/SSL encryption, auditing, and more, that can be used to protect a database deployment.
• Also, it gives you a security checklist, which is a list of recommended security measures you need to take to protect a MongoDB deployment. Also, make sure that security at the network and server levels is tight.
