Why Use MongoDB And When To Use It?

Scaling horizontally means adding more servers to distribute the load across multiple nodes. These collections hold multiple documents, and since MongoDB is schemaless, the documents in one collection need not be similar. All data is stored as BSON documents with the help of key-value pairs.

Use MySQL if you require a high transaction rate, the security that comes with referential integrity, or if you have a data structure that isn’t likely to change. Records in a MongoDB database are called documents, and the field values may include numbers, strings, booleans, arrays, or even nested documents. Unique Identification Authority of India operates India’s biometric system, an extensive database system launched in 2009. The program stores biometric information of more than 1 billion Indians. This massive amount of data requires a well-suited database system.

These drivers are responsible for sending and receiving data in BSON format. Encoding to BSON and Decoding to BSON again happens very quickly, and so it’s so efficient. Here are a few terms related to MongoDB, which is used while using it. With MongoDB seemingly turning the corner, there’s clearly a fundamental case to be made as to why this stock is a solid investment right now. Developers, MDB’s target customer, are always keen to “kick the tires” of a new technology.

When a primary replica fails, the replica set automatically conducts an election process to determine which secondary should become the primary. Secondaries can optionally serve read operations, but that data is only eventually consistent by default. One of MongoDB’s biggest advantages over other databases is its ability to handle ad hoc queries that don’t require predefined schemas.

Rapidly rising inflation and interest rates are usually bad for all stocks, but especially for unprofitable stocks that don’t pay out dividends to shareholders. This is for a number of reasons; rising rates increase the attractiveness of short-term bonds over stocks, giving stocks competition for investment dollars. Rising interest rates also slow the economy by making borrowing more expensive. Therefore, if a stock is printing losses today, with the bulk of its value in cash flows many years out, its valuation will suffer disproportionately in a higher-rate environment.

MongoDB provides a number of features that make it a great choice for a wide variety of applications. MongoDB is one of the most popular NoSQL databases and has been widely used in different industries and use cases. Multiple shards – contain a subset of the sharded data, wherein each shard can be deployed as a replica set. The multiple shards represent a horizontal scale-out architecture since shards are deployed in multiple servers. The document-oriented approach allows non-defined attributes to be modified on the fly.

Applications use databases via programming language code to store or get the necessary data. For example, when you create an online profile on a social media platform, the data you provide is stored in a database for future use. However, MongoDB’s pay-as-you-go model, which also exists, is widely used here, as business-critical applications can rarely do without a fully managed failover and complex recovery options. But the community server version available free of charge at is an excellent way to enter the NoSQL world with this database. The combination of the MongoDB document model and the distributed system components gives MongoDB an advantage over relational databases.

MongoDB’s load balancingsharing process distributes large data sets across multiple virtual machinesat 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. MySQL uses a structured query language to access stored data. In this format, https://globalcloudteam.com/ schemas are used to create database structures, utilizing tables as a way to standardize data types so that values are searchable and can be queried properly. A mature solution, MySQL is useful for a variety of situations including website databases, applications and commercial product management. With automatic failover and horizontal scaling, MongoDB is an open source database built for modern applications.

  • Databases are used to perform operations on data, like insert , Read, Update, and Delete .
  • Queries can return specific fields and also account for user-defined functions.
  • The current database version is now displayed on the right-hand side of the screen and you can click on the green download button with the preset values.
  • This article explains how MongoDB works, its architecture, key features, and six real-world examples of MongoDB applications.
  • Due to the default security configuration of MongoDB, allowing anyone to have full access to the database, data from tens of thousands of MongoDB installations has been stolen.
  • “In 2019, multiple open source companies changed course—is it the right move?”.
  • While this minimizes data duplication, it results in millions of reads and writes that can affect performance.

This is in broad contrast to the relational database with a fixed schema structure, ensuring similar data is entered into rows within a table. Within the collections are documents analogous to rows in a table in the relational database system. Documents are made up of keys, the most basic data unit in MongoDB. Replication – MongoDB can provide high availability with replica sets. A replica set consists of two or more mongo DB instances. Each replica set member may act in the role of the primary or secondary replica at any time.


Then you install the mongo shell on your computer and connect to the user account on the cluster. 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 Atlas allows developers to get started right away in any major public cloud and easily migrate on-premise MongoDB instances to the cloud.

After all, if so many potential users are demonstrating interest in the technology, they must arguably reflect a very large TAM. Connect Using the SAP HANA Go InterfacePlease make sure that you follow the steps till “Create a Go application that queries an SAP HANA database”, because 3. Will have to be performed to finish the setup of go-hdb.

When your data only resides in a single server, it is exposed to multiple potential points of failure, such as a server crash, service interruptions, or even good old hardware failure. Any of these events would make accessing your data nearly impossible. You are not the only one asking this seemingly popular question!

While using W3Schools, you agree to have read and accepted our terms of use,cookie and privacy policy. Cloud computing management, search suggestions, and categorization of items, are done using MongoDB. Computer network service may be interrupted, and other similar events can make it difficult for an individual to access data. MongoDB is a type of NoSQL database that is used for managing large volumes of data. The name “Mongo” comes from “Humongous,” describing the data size the software is meant for. While MongoDB may not be for everyone, it is a type of database system that organizations handling big data want to work with.

MongoDB databases use a query language that’s similar to SQL databases and is extremely approachable for beginner and advanced developers alike. This accessibility makes it easy to push, query, sort, update and export your data with common help methods and simple shell commands. However, it can’t match MongoDB’s flexibility for handling structured and unstructured data sets or its performance and reliability for mission-critical cloud applications. MongoDB is a flexible, document-oriented database platform that is designed to be the cloud database of choice for enterprise applications.

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.

For example, a database can store a customer’s details like name, birthday, address, order details, family details, occupation details, preferences, and much more. All of this data can be collected from various sources and put together in one place, and stored under a common name . With the command “show dbs“, the three preset databases admin, config and local should now be displayed.

When there comes, the scenario of storing data, storing it in columns and rows form is a traditional way as it led to ample of space wastage. Today’s enterprise is far more flexible and beyond expectations. For better customer service and modern application development, an enterprise should be ready to adopt any changes and fulfill the expectations. It handles all the data requests, manages data access, and performs various background management operations.
