What Are The Top 10 Key Features Of MongoDB?

By using this, you can create internal tools, GUIs, Admin Panels, Dashboards, and custom apps. DronaHQ’s MongoDB GUI tool makes it easy to create fully-featured MongoDB GUIs with pre-built UI controls and a WYSIWYG editor. Consequently, CRUD operations have become much quicker and easier.

Redis, for instance, is a key-value database that is optimized for tracking relatively simple data structures in a persistent database. In MongoDB documents, you are allowed to store nested data. In SQL, you need to write complex joins to get the data from table 1 and table 2. One of the most primarily discussed features of MongoDB is, it being Schemaless. Meaning that there can be multiple documents in a collection, with different keys, and these keys might not be found in other documents. This is the major reason behind MongoDB’s flexibility, with data.

Fields are key-value pairs in the documents, it is just like columns in the relation database. The value of the fields can be of any BSON data types like double, string, boolean, etc. The MongoDB database contains collections just like the MYSQL database contains tables. You are allowed to create multiple databases and multiple collections.

Robo 3T is the best GUI application if you are a beginner and want something with a supportive community. However, Studio 3T would be better suited for those who are experienced and looking for an upgrade from Robo 3T. Creating a form with HumongouS.io is as easy as one click.

Overview of MongoDB

New operators including accumulators to compute items based on their place in a dataset and $sortArray to sort the items in an array. Secure sensitive data by omitting the critical or unused fields. In this article, you will learn about MongoDB Filtering and how you can apply filters to your queries. Relational databases are known for enforcing data integrity. The _id field is added by MongoDB to uniquely identify the document in the collection.

A dark or light theme in UI is only a matter of your preference. The list of supported languages includes Node.js, C, C++, C#, Go, Java, Perl, PHP, Python, Ruby, Rust, Scala, and Swift. The library for each language is actively maintained, which means that it is updated with new features, bug fixes, security patches, and performance enhancements.

MongoDB is an open-source document-oriented database that is designed to store a large scale of data and also allows you to work with that data very efficiently. It is categorized under the NoSQL database because the storage and retrieval of data in the MongoDB are not in the form of tables. In the above Document, we have four key values, where _id is default and set automatically—this the basic structure of a document-based database.

You have a number of parameters to control the storage of time series data, including the granularity and the expiration threshold of old data. Database triggers in MongoDB Atlas are a powerful feature that allow you to execute code when certain events occur in your database. For example, you can use triggers to execute a script when a document is inserted, updated, or deleted. Triggers can also be scheduled to execute at specific times. MongoDB provides a number of authentication mechanisms for users to access the database.

How do key-value databases work?

MongoDB is a document database, which means that it stores data in the form of “objects” which have properties that can be changed, added to, deleted, and queried against. While in an academic sense, MongoDB stores values for keys , it would be a bit of a simplification to call MongoDB simply a key-value database . MongoDB documents https://globalcloudteam.com/ can form compact flexible structures to support fast indexing for your key-value stores. MongoDB Atlas, the cloud developer data platform by MongoDB, makes it easier than ever to keep your data secure. In addition to the authentication, authorization and encryption features discussed, it offers advanced security features.

And if the former primary node comes back online, it does so as a secondary server for the new primary node. Replication allows you to sidestep these vulnerabilities by deploying multiple servers for disaster recovery and backup. Horizontal scaling across multiple servers greatly increases data availability, reliability, and fault tolerance. Potentially, replication can help spread the read load to the secondary members of the replica set with the use of read preference. However, the documents in a single collection don’t necessarily need to have exactly the same set of fields.

Is MongoDB secure?

Clients can iterate through a cursor to retrieve results. MongoDB has been adopted as backend software by a number of major websites and services including EA, Cisco, Shutterfly, Adobe, Ericsson, Craigslist, eBay, and Foursquare. Data-flair.training needs to review the security of your connection before proceeding. Mail us on , to get more information about given services. Embedded documents and arrays reduce need for expensive joins.

Documents correspond to native data types in many programming languages. Try MongoDB Atlas as your key-value database and reveal new possibilities to innovate your applications. Real time random data access, e.g., user session attributes in an online application such as gaming or finance. DOCUMENTATION Learn more about all the security features in the MongoDB platform by looking at our docsDOCUMENTATION Find out more about the security features in MongoDB Atlas. Aggregation Framework is one of the most efficient features offered by MongoDB.

  • MongoDB is a document database, which means that it stores data in the form of “objects” which have properties that can be changed, added to, deleted, and queried against.
  • Compare that to a traditional relational database table, where adding a field means adding a column to the database table itself and therefore to every record in the database.
  • When we are encountered with large datasets, we can implement the Sharding of Data.
  • Aggregation Framework is one of the most efficient features offered by MongoDB.
  • The list of supported languages includes Node.js, C, C++, C#, Go, Java, Perl, PHP, Python, Ruby, Rust, Scala, and Swift.

The major and very common problem with a growing web application is scaling. To overcome this, MongoDB has come up with Sharding feature. Sharding is a method for distributing data across multiple machines. MongoDB uses sharding to support deployments with very large data sets and high throughput operations. Sharding makes it possible to provide horizontal scalability.

What is the difference between a key-value database and a document database?

MongoDB is well known for its horizontal scaling and load balancing capabilities, which has given application developers an unprecedented level of flexibility and scalability. MongoDB supports field, range queries, regular expression searches. Queries can return specific fields of documents and also include user-defined JavaScript functions. MongoDB is able to support ad hoc queries by indexing BSON documents and using a unique query language.

MongoDB Key Features

Ensure that your data is encrypted by using TLS/SSL and client-side field level encryption. Specify who has access to what resources through fine-grained role-based access control . Amongst other things, MongoDB offers authentication, authorization and encryption to help you secure your MongoDB deployments. Show DBS will list every collection or table present in the DB. Let’s take a look at some of the most essential technical features of MongoDB. MongoDB provides developers with a number of useful out-of-the-box capabilities, whether you need to run privately on site or in the public cloud.

Cosmos DB & MongoDB API

It’s one of the best MongoDB GUIs on the market, offering features like query auto-completion, schema visualization, and support for MongoDB’s aggregation framework. Some people needed a Database that could store lots of unstructured postgresql has many modern features including data. So Dwight Merriman, Eliot Horowitz, and Kevin Ryan created MongoDB. What makes MongoDB stand out is its horizontal scalability and load-balancing capabilities which provide users with unmatched levels of flexibility.

MongoDB Key Features

If you are familiar with relational databases, you can think of a collection as a table. Collections do not enforce a schema, and documents in the same collection can have different fields. MongoDB is a document-oriented NoSQL database used for high volume data storage. Instead of using tables and rows as in the traditional relational databases, MongoDB makes use of collections and documents. Documents consist of key-value pairs which are the basic unit of data in MongoDB.

MongoDB 5.0 and Rapid Releases: Guide to What’s New

The benefit is the lack of setup and the reduced friction with OOP. So, in order to save an object, you just have to serialize it to JSON and send it to MongoDB. There is no need for type mapping which removes an additional burden. The aggregation framework enables users to obtain the kind of results for which the SQL GROUP BY clause is used.


This MapReduce can be used to parallelize, allow huge data for processing over lots of cores/machines. MongoDB is known for being an easy-to-use database, but sometimes you need a little help getting started. A MongoDB GUI can make working with your database much easier, whether you’re a beginner or an experienced user. It offers a variety of options, like a simple on & off switch, or more complex features like a rich text field or an s3 file uploader. No matter what your needs are, HumongouS.io have you covered.

Chosen carefully, indexes speed up queries because queries scan the index instead of reading every document in the collection. MongoDB is highly flexible as it supports several programming languages such as C, C++, C#, Go, Java, Node.js, Perl, PHP, Python, Motor, Ruby, Scala, Swift, and Mongoid. As we have seen from the Introduction section, the data in MongoDB has a flexible schema. Unlike in SQL databases, where you must have a table’s schema declared before inserting data, MongoDB’s collections do not enforce document structure. This sort of flexibility is what makes MongoDB so powerful. Database – This is a container for collections like in RDMS wherein it is a container for tables.
