Mongo DB, a NoSQL database, revolutionized data management in modern applications since 2007. It’s flexible, scalable, and efficient with large datasets, storing information in JSON-like documents called BSON. However, Developers love it for its adaptability to changing data needs. This guide from The IoT Academy explains MongoDB’s history, how it works, what it’s used for, its features, and more, using practical examples to show how versatile it is. Whether you’re a developer or just curious, this article makes understanding MongoDB easy.
MongoDB is a free, open-source database that stores information in flexible, JSON-like documents. It’s great for storing and retrieving data in a way that can grow as needed. However, Moreover, Mongo DB is easy to use and works well for both small projects and big business systems. Generally, It can adapt to changes easily without causing disruptions, and many developers use it for building modern websites.
In 2007, 10gen (now MongoDB Inc.) created Mongo DB, a NoSQL database, to address issues with traditional databases. The name “Mongo” comes from “humongous.” As well as Launched in 2009, MongoDB became popular for its simple way of handling data in evolving applications.
In short, It’s a top pick for web developers due to its speed and ability to handle growing data. However, Mongo DB is open-source, meaning it’s free to use and has strong features, making it widely used in different industries.
MongoDB is a type of database that stores information in flexible, JSON-like documents called BSON. Instead of tables, it organizes data into collections and databases. Each piece of data is like a document with key-value pairs. MongoDB is good for handling lots of data because it spreads it across many servers.
Along with this, It’s easy to adapt as data changes because of its dynamic schema. You can search for data using a simple JSON-like language. Mongo DB’s features like indexing and sharding make it perform well and retrieve data efficiently in different applications.
Lots of people use Mongo DB because it’s a free NoSQL database that handles big data, works fast, and lets you organize data flexibly. In addition, Here are some common uses of MongoDB:
While MongoDB is versatile, the best database choice depends on a project’s needs, and it may not be ideal for every application.
Some of the key features of Mongo DB are as follows:
These features collectively make MongoDB a popular choice for developers working on a variety of applications, especially those dealing with large and dynamic datasets.
MongoDB, a popular NoSQL database, offers several advantages that make it a preferred choice for certain applications. Here are some of the key advantages of MongoDB:
While MongoDB is a popular NoSQL database with several advantages, it also has some disadvantages that users should consider:
Ultimately, Here’s a brief comparison table between MongoDB (a NoSQL database) and RDBMS (Relational Database Management System):
| Feature | MongoDB | RDBMS |
|---|---|---|
|
Data Model |
Document-oriented, NoSQL |
Tabular, relational |
|
Schema |
Dynamic schema (schema-less) |
Fixed schema (schema-defined) |
|
Scalability |
Horizontal scaling (sharding) |
Vertical scaling (adding more resources) |
|
Query Language |
JSON-like queries (MongoDB Query Language) |
SQL (Structured Query Language) |
|
Relationships |
Embedded documents or references |
Foreign keys for relationships |
|
ACID Transactions |
Limited support (ACID for single documents) |
Full ACID compliance |
|
Scaling Performance |
Excellent for read-heavy workloads, suitable for large datasets |
Well-suited for complex transactions, maintains data integrity |
|
Flexibility |
Flexible schema allows for easy modifications |
Rigid schema ensures data consistency |
|
Use Cases |
Big data, real-time applications, agile development |
Traditional business applications, structured data |
However, Here are five examples of Mongo DB queries and operations:
|
db.users.insert({ name: “IoT Academy”, age: 30, email: “IoT@academy.com”, address: { city: “Noid Sec-62”, zip: “201309” } }) |
|
db.users.find({ age: { $gte: 25 } }) |
|
db.users.update( { name: “Ankit Roy” }, { $set: { age: 65, email: “ankit.roy@theiotacademy.com” } } ) |
|
db.users.remove({ name: “Ankit Roy” }) |
|
db.orders.aggregate([ { $match: { status: “completed” } }, { $group: { _id: “$product”, totalAmount: { $sum: “$amount” } } }, { $sort: { totalAmount: -1 } } ]) |
Secondly, It combines orders, selects those marked as completed, groups them by product, calculates the total amount for each product, and finally arranges the results from highest to lowest total amount.
In conclusion, MongoDB, born in 2007, changed how we manage data by being flexible, scalable, and efficient. With its JSON-style documents and adaptability, it’s a favorite for developers. Great at handling big data, Mongo DB lets you scale easily and work with data swiftly. Besides, While it has a few downsides, it’s a strong tool that has played a big role in shaping today’s database management.
Ans. No, MongoDB isn’t a backend language; it’s a type of database called NoSQL. However, People use it with languages like JavaScript, Python, or Java on the backend to create whole applications with both front and back parts.
Ans. MongoDB is mostly written in C++. It uses a format called BSON to store data in a way similar to JSON. C++ helps MongoDB perform well, scale easily, and manage large amounts of data efficiently.
