MongoDB Index & Index Types

MongoDB Index & Index Types  Introduction MongoDB, a powerful NoSQL database, is designed for scalability, high availability, and performance from single server deployments to large complex multi-site architectures. One of the essential features of MongoDB that helps in achieving these goals is the Index. What is an Index? An index in MongoDB is a special data structure that holds the data of few fields of documents on which the index is created. Indexes improve the performance of search operations in the database as they provide a more efficient path to the data. Just as an index in a book helps you locate content quickly, a MongoDB index allows the database to find and retrieve specific documents much faster than it would without an index. How to create an index:- Now that we have an understanding of what indexes are and when to use them, we can get into the method of creating one. Once you have identified a field that could benefit from indexing, you use the createIndex() me...

MongoDB CRUD Operations

MongoDB CRUD Operations. MongoDB is a persistent document-oriented database used to store and process data in the form of documents. As with other database management systems, MongoDB allows you to manage and interact with data through four fundamental types of data operations: In this article, we will learn all 4 major operations– CREATE, READ, UPDATE, and DELETE that form the CRUD operations in MongoDB. What is CRUD in MongoDB? CRUD operations describe the conventions of a user interface that let users view, search, and modify parts of the database. MongoDB provides an elegant way of performing CRUD operations with the programming language of your choice through its drivers. MongoDB documents are modified by connecting to a server, querying the proper documents, and then changing the setting properties before sending the data back to the database to be updated. When it comes to the individual CRUD operations: C :-Create operations, which involve writing data to the database. R :-Read...

How to manage users and authentication in MongoDB/MongoDB Role-Based Access Control

Image
How to manage users and authentication in MongoDB Managing users and authentication are some of the most important administration tasks of managing MongoDB servers. You must ensure that the server is configured to be able to properly identify your users and applications and deny connections or operations that are unable to authenticate correctly. To manage these requirements, you must be able to decide which the users your server requires and create those accounts. As part of this process, you can set the authentication details to allow external access using the new identity. MongoDB is a powerful, open-source NoSQL database that supports flexible data structures, easy scalability, and efficient performance. Understanding how to manage users and roles is critical for maintaining database security. In this tutorial, we’ll explore how to create users, define roles, and grant privileges in MongoDB. Irrespective of whether you’re running a local instance or deploying on a large-scale, thes...

MongoDB Architecture

Image
  MongoDB Architecture MongoDB is a popular NoSQL document-oriented database management system, known for its flexibility, high performance, high availability, and multi-storage engines. The term NoSQL means non-relational. It means that MongoDB isn’t based on a table-like relational database structure. It is used by Adobe, Uber, IBM, and Google. In this article, we will delve into the MongoDB architecture, exploring its key components and how they work together. Key Features of MongoDB:- Document-oriented Database Stores data in BSON-like documents. Schema Less database. It provides horizontal scalability with the help of sharding. It provides high availability and redundancy with the help of replication. It allows one to perform operations on the grouped data and get a single result or computed result. It has very high performance. MongoDB Architecture and its Components:- MongoDB’s architecture design involves several important parts that work together to create a strong and fle...
