What is MongoDB? Non-relational Database

So, that you can create an application using any of these languages. Nowadays there are so many companies that used MongoDB like Facebook, Nokia, eBay, Adobe, Google, etc. to store their large amount of data. 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 (Not only SQL) database because the storage and retrieval of data in the MongoDB are not in the form of tables.

As enterprises’ cloud applications scale and resource demands increase, problems can arise in securing the availability and reliability of services. MongoDB’s load balancing sharing process distributes large data sets across multiple virtual machines at once while still maintaining acceptable read and write throughputs. This horizontal scaling is called sharding and it helps organizations avoid the cost of vertical scaling of hardware while still expanding the capacity of cloud-based deployments. As companies scale their operations, gaining access to key metrics and business insights from large pools of data is critical.

How to install MongoDB on Windows 10

Later in 2009, it is introduced in the market as an open source database server that was maintained and supported by MongoDB Inc. The initial development of MongoDB began in 2007 when the company was building a platform as a service similar to window azure. In simple words, you can say that – Mongo DB is a document-oriented database.

They are built for high throughput, so developer platforms like MongoDB are superfast and come with automatic features to help maintain your applications. MongoDB is a great choice to support applications that need to handle various types of data (structured, semi-structured and unstructured) as well as needing to utilize large amounts of data. MongoDB works well when an application needs high availability of data, flexibility of data storage, postgresql document database ability to scale-out quickly or the ability to support real-time analytics and big data needs. MongoDB instances can scale horizontally through a process called sharding. Sharding refers to the process wherein data from a large data set is divided and automatically distributed across multiple servers. If one server can’t handle a data load, it can be divided and distributed to other servers without any interruption to data processing.

In general, you should use a custom user with specific privileges to limit access and increase security. If you’re using a cloud or local installation, we recommend you install the command line mongosh MongoDB Shell. All examples were developed using MongoDB 5 but most will work in previous or later versions.

Imagine that you own a department store and want to capture the sales per item per month. This is an aggregation that can be configured to occur automatically upon insertion of new data in a configured MongoDB collection. Moreover, MongoDB Atlas offers you the capability to add explanatory visualizations using MongoDB Charts, including adding bar charts, line charts, or even geospatial graphs like choropleths, scatter plots, or heat maps. In this query, we are filtering records from the inventory collection. We are using the logical operator $and to only get documents that have a price data field ($exists) and that are equal ($eq) to 2.00.

Capped collections

Third, MongoDB has a flexible schema that facilitates faster development. Relational databases, on the other hand, require defining and maintaining schemas, indices, and relationships, thus making them more complex. In our experience, the number one issue that many technical support teams fail to address with their users is indexing.

It is an open source product, developed and supported by a company named 10gen. MongoDB Course from Intellipaat will provide you with the right set of skills to work with NoSQL databases in the best companies. Dwight Merriman, Eliot Horowitz, and Kevin Ryan created MongoDB in 2007. To provide a solution for the problems of scalability and agility that they were facing at DoubleClick, they decided to develop a database.

Work with your data in MongoDB

Applications get the power and responsibility to interpret different properties found in a collection’s documents. This method is best for inserting a single document in a collection and accepts two arguments. First is the mandatory document argument; it specifies the document that must be inserted into the collection. Second is the optional writeConcern argument; it explains how MongoDB will acknowledge the insert operation.

You could use a hosted MongoDB instance so there’s no need to install anything locally. An internet connection is essential and the speed of response will depend on the host and your bandwidth. This will take a few minutes on the first launch, but subsequent runs are considerably faster. Note that MongoDB uses similar JavaScript object notation for data updates and queries, which can pose some challenges if you’re used to SQL. MongoDB offers an Extract, Transform, Load (ETL) framework which eliminates the need for complex data pipelines.

Programming language accessibility

MongoDB’s scale-out architecture, which distributes work across many smaller (and cheaper) computers, means that you can create an application that will handle spikes in traffic as your business grows. MongoDB Atlas allows developers to get started right away in any major public cloud and easily migrate on-premise MongoDB instances to the cloud. With MongoDB Atlas, the database-as-a-service at the center of the MongoDB Cloud, it is easier than ever to use MongoDB. You can provision a cluster with a few clicks from the web interface and start writing code almost immediately. This is unlikely to be a problem while using mongosh, but applications can reach this limit if they make a series of data manipulations on individual records.

  • MongoDB acts as a database server where organizations can maintain several databases.
  • It’s rarely necessary to read documents and manipulate the data in your application code directly.
  • Adminer is a web-based database client which supports MongoDB, though it is currently limited to inspecting collections.
  • A primary server or node accepts all write operations and applies those same operations across secondary servers, replicating the data.
  • There are other ways to achieve this result, but the key point is that MongoDB can do the bulk of the work.
  • Originally designed for the needs of ad-serving, which required fast parallel access but less real-time analysis.

As a definition, MongoDB is an open-source database that uses a document-oriented data model and a non-structured query language. It is one of the most powerful NoSQL systems and databases around, today. With the rise in data all around the world, there has been an observable and increasing interest surrounding the wave of the non-relational database, also known as ‘NoSQL‘. MongoDB’s namesake product is a database management system that allows organizations to store large amounts of unstructured data more efficiently.
