When modeling data in MongoDB, it is common to embed objects within each other. What used to take multiple transactions to update in traditional relational databases can sometimes be achieved in a single transaction with MongoDB.
If still needed, MongoDB also supports database transactions that allow many changes to a database to be grouped and either made or rejected in a batch. MongoDB has been around since and has been deployed at thousands of companies for a wide range of use cases. A natural result of that usage level is that the platform has been extended to meet a massive number of new demands. Most large organizations want to make sure it is easy to get help using any technology that becomes the foundation of their business.
MongoDB has a large and thriving community of developers across the open-source community, academia, and among system integrators and consulting firms across the globe.
MongoDB is a general-purpose database used in various ways to support applications in many different industries e. MongoDB has found a home in many different businesses and functions because it solves long-standing problems in data management and software development. Typical use cases for MongoDB include:. MongoDB is a general-purpose database that can provide many benefits to your application development processes.
It can help you build applications that are more future-proof with its scaling capabilities and flexible schema. It offers a great developer experience with drivers for most major programming languages and a large community of users. It is also available on any of the major cloud providers.
Why not give it a try right now with MongoDB Atlas? Once you have access to your cluster, you can take a look at MongoDB University for an extensive offering of free courses to help you explore the benefits of using MongoDB.
MongoDB Atlas is a fully-managed database as a service that runs on all public clouds. It scales from a free tier no credit card required to global clusters. All of the functionality of MongoDB is available through the CLI, which uses the mongo shell to enter commands and receive output. To use the mongo shell, you must have a user set up on a MongoDB cluster. Then you install the mongo shell on your computer and connect to the user account on the cluster.
At this point, you are off and running and can enter commands to configure the cluster, create databases, or get information about how the cluster is running. MongoDB Compass provides a way to visualize your data, create indexes, and assemble complex aggregation pipelines that streamline how you work with data. It stores information as structured or unstructured objects called documents.
These documents are grouped in collections. Using MongoDB can provide many benefits to a software development team. Its flexible schema makes it easy to evolve and store data in a way that is easy for programmers to work with.
The data fields can be of an arbitrary number and type, even within the same collection. An example of a document is:. MongoDB can handle dynamic data models and schema that can easily store unstructured data sets; and in the case of variable data loads, MongoDB can scale horizontally, which is extremely cost-efficient when compared to traditional SQL databases, which can usually only scale vertically.
There are a few ways to install MongoDB. This is a service that you can access using your favorite web browser; it can be installed on all three major public cloud providers Amazon Web Services, Microsoft Azure, Google Cloud Platform , comes with a free tier, and with just a few clicks, you will have provisioned a fully functioning MongoDB database.

If this is your first time trying out MongoDB, then it is highly recommended to use MongoDB Atlas due to its ease of use in quickly provisioning a free cluster.
If you have used MongoDB Atlas, you can easily inspect the status of your cluster from the Clusters home page:. If you have installed MongoDB Community Edition on a personal workstation with Windows, Macbook, or Linux, you need to check whether the mongod process is running on localhost, respective to your OS-specific commands. Depending on your preferences, you have a few options for how to interact with the database that you just created:. For explanatory tasks, it is a good idea to work with the MongoDB Atlas web UI, but if your intentions are to automate document loads onto MongoDB, then switching to a programming language is going to be a better option since it will give you greater control.
As discussed above, once you pick your preferred interaction option, it is very easy to get started in creating your first MongoDB collection.
