MongoDB offers a flexible framework for creating data processing pipelines called aggregation pipelines. It features dozens of stages and over 150 operators and expressions, enabling you to process, transform, and analyze data of any structure at scale. One recent addition is the Union stage, which flexibly aggregate results from multiple collections. Since MongoDB documents can be complex objects, applications can use a schema design to minimize index footprints and optimize access for a “key-value” approach. This design pattern is called the Attribute Pattern and it utilizes arrays of documents to store a “key-value” structure. MongoDB, being one of the most widely used NoSQL databases, provides a wide range of features and functionalities.
MongoDB provides a default ‘_id’ which is a 12-byte hexadecimal number that assures the uniqueness of every document. Now a day many companies using MongoDB to create new types of applications, improve performance postgresql has many modern features including and availability. Indexes support faster queries and can include keys from embedded documents and arrays. As a result, our queries will have a full per field-value query supported by this index.
MongoDB is faster as compared to RDBMS due to efficient indexing and storage techniques. Complex transactions are not supported in MongoDB because complex join operations are not available. In addition, MongoDB provides pluggable storage engine API that allows third parties to develop storage engines for MongoDB. Data is written and queried based on the key to store/retrieve its value. You need not to design the schema of the database when you are working with MongoDB. The above query will return documents that have Pune as their City, and it will print the sorted result.
Documents in MongoDB are stored in the BSON format, which is a binary-encoded JSON format. This means that the data is stored in a binary format, which is much faster than JSON. This also allows for the storage of binary data, which is useful for storing images, videos, and other binary data. Even though BSON is a binary-encoded format, it’s easy to work with it using the MongoDB driver for your programming language.
How secure is MongoDB Atlas?
MongoDB is such a NoSQL database that scales by adding more and more servers and increases productivity with its flexible document model. A replica set is a group of MongoDB servers that maintain the same data set, providing redundancy and increasing data availability. In other words, MongoDB’s document database is a superset of a key-value store as it supports much more. MongoDB Atlas has all the modern security features you would expect from a cloud based data platform.
It enables the database engine to efficiently resolve queries which make it one of the best key features of MongoDB. Replication – MongoDB can provide high availability with replica sets. A replica set consists of two or more mongo DB instances.

You are not allowed to store more than 16MB data in the documents. The first one is created on “_id” which is default and created automatically. MongoDB Atlas is MongoDB’s DBaaS (Database-as-a-Service) platform offering that provides a fully managed MongoDB cluster with a dedicated MongoDB instance for each user. Atlas has all the features of a MongoDB Enterprise instance, plus the ability to scale horizontally and vertically in a click of a button. You can get started with MongoDB Atlas today by creating a free cluster.
The filter can add extra query parameters and omit fields from query results before App Services runs the query. Image SourceMongoDB is a popular Free and Open-Source Cross-Platform Document Oriented Database built for efficiently storing and processing massive volumes of data. Each collection consists of multiple documents that contain the basic units of data in terms of key and value pairs. Document-oriented – Since MongoDB is a NoSQL type database, instead of having data in a relational type format, it stores the data in documents.
Atom vs Visual Studio Code: Most Significant Differences To Know
And, MongoDB has brought in some more, very important and useful features. The easy-to-use visual builder offers form fields, charts, lists, buttons, table grids, detailed views, and custom UI control. The GUI-based query builder also allows for server-side filtering using MongoDB GUI across all of your databases, whether SQL or NoSQL.
- MongoDB has a flexible schema that uses JSON-like documents.
- Data relations are easy to view with Mingo – simply open up a document and preview the data relations directly within it.
- You have a number of parameters to control the storage of time series data, including the granularity and the expiration threshold of old data.
- This allows you to do everything in Robo 3T that you could do in the mongo shell.
- Using Atlas, developers can deploy fully managed cloud databases across AWS, Azure, and Google Cloud.
- With its flexible schema and rich query language with secondary indexes, MongoDB is a compelling store for “key-value” data.
These features help you and your team ensure that all of your data is stored safely and securely. Time series data is most commonly generated by a device, such as a sensor, that records data over time. The data is stored in a collection of documents, each of which contains a timestamp and a value. MongoDB provides a number of features to help you manage time series data.
NoSQLBooster provides an all-inclusive GUI for MongoDB, complete with SQL query support, script debugger, server monitoring, and true IntelliSense. NoSQL Booster’s IntelliSense language service is similar to Studio 3T’s IntelliShell and provides completions, collection names, properties, and field names as you type. Provides drivers for many programming languages that can be used to write MongoDB applications. One of the benefits of MongoDB over other databases is that it has dynamic schemas, which means that data integration for certain kinds of applications can be done more quickly. Add referenced fields to target collections automatically etc.
Authentication ensures that only authorized users can access the database. MongoDB Atlas, MongoDB’s DBaaS (Database-as-a-Service) platform, has a minimum of three member replica sets. They can span across multiple regions or even multiple cloud providers of your choice. MMS is a powerful web tool that allows us tracking our databases and our machines and also backing up our data. MMS also tracks hardware metrics for managing a MongoDB deployment.
The above query will return every index that has been created for the “test” collection. Below is a simple query returning the list of collections in the Database. Check out the dedicated Database Sharding article to learn more about the different sharding architectures and what problems they solve. DronaHQ’s MongoDB connector lets you connect to any type of MongoDB database, whether it is self-hosted or managed. You can also use a connection string to interact with data in the most efficient way possible. Database modeling allows all your team members or clients to understand the references among objects in your MongoDB/Mongoose structures in an effective manner.
This makes MongoDB very flexible and adaptable to real business world situation and requirements. MongoDB, the most popular NoSQL database, is an open-source document-oriented database. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data.
What is MongoDB? Introduction, Architecture, Features & Example
A master can perform Reads and Writes and a Slave copies data from the master and can only be used for reads or back up . Another robust feature of the MongoDB replica set is its automatic failover. When one of the set members can’t reach the primary instance for more than 10 seconds, the replica set will automatically elect and promote a secondary instance as the new primary.
In our experience, the number one issue that many technical support teams fail to address with their users is indexing. Done right, indexes are intended to improve search speed and performance. A failure to properly define appropriate indexes can and usually will lead to a myriad of accessibility issues, such as problems with query execution and load balancing. MongoDB supports field queries, geo queries, and regular expression searches.

MongoDB as a key-value store
Each database gets its own set of files on the file system. This data is stored in a predefined data model which is not very much flexible for today’s real-world highly growing applications. Modern applications are more networked, social and interactive than ever. Applications are storing more and more data and are accessing it at higher rates.
The app also provides comprehensive documentation, making it a great resource for learning about MongoDB. MongoDB shards data at the collection level, distributing documents in a collection across the shards in a cluster. The result is a scale-out architecture that supports even the largest applications. MongoDB is a general-purpose document database designed for modern application development and for the cloud.
