  Introduction to MongoDB MongoDB is a NoSQL document-oriented database system. It is a highly scalable, flexible, and fast database system that provides high performance, high availability, and automatic scaling. MongoDB is an open-source database system that stores data in a JSON-like format, which allows it to work with a wide range of applications and programming languages. Features of MongoDB Document-oriented storage: MongoDB stores data in flexible, JSON-like documents, meaning fields can vary from document to document and data structure can be changed over time. Ad hoc queries: MongoDB supports ad hoc queries by indexing data and providing query optimization capabilities to support fast queries. Indexing: MongoDB can create indexes to improve the performance of queries and reduce the time needed to retrieve data. Replication: MongoDB provides high availability by replicating data across multiple servers. Sharding: MongoDB provides horizontal scaling by sharding data across mult

MongoDB is a popular NoSQL document-oriented database used for handling large volumes of data. In this tutorial, we will cover the basics of MongoDB and how to interact with it using the MongoDB shell. Installation and Setup: To get started with MongoDB, you need to install it on your system. You can download the appropriate version of MongoDB for your operating system from the official website ( https://www.mongodb.com/try/download/community ). After downloading and installing MongoDB, you should start the MongoDB server by running the following command: mongod Connecting to MongoDB: To connect to MongoDB, open a new terminal window and run the following command: mongo This will open the MongoDB shell. C reating a Database: To create a new database, use the use command followed by the name of the database you want to create: use mydatabase If the database doesn't exist, it will be created automatically. Creating a Collection: A collection is a group of related documents s

  Introduction MongoDB is a popular NoSQL database that uses a document-oriented data model. Unlike traditional relational databases, MongoDB does not use tables, rows, or columns to store data. Instead, it uses collections of documents, which are similar to JSON objects. MongoDB was developed by MongoDB Inc. and released in 2009. It is written in C++ and is available under the Apache License 2.0. Document-oriented data model In MongoDB, data is stored in collections, which are similar to tables in relational databases. However, unlike tables, collections do not enforce a fixed schema. Each document in a collection can have its own set of fields and data types, making MongoDB highly flexible. Documents in MongoDB are stored in BSON format, which is a binary representation of JSON. BSON allows for efficient storage and retrieval of data, and also supports additional data types such as binary data and date/time values. Query language MongoDB provides a rich query language for searching a
