A Significant Difference Between Both SQL vs MongoDB

We will discuss the complete difference to clarify the confusion of those looking for SQL vs MongoDB. There are two types of databases available: SQL and NoSQL. MySQL is an example of a SQL database, whereas MongoDB is an example of a NoSQL database. MongoDB collects data in JSON-like documents with variable structure, allowing for a dynamic and adaptable schema. With auto-sharding, MongoDB was intended for scalability and high availability. For e-commerce and data warehousing purposes, SQL Server is a database administration and analytical system. MongoDB is one of the many databases that fall under the NoSQL database category and store large amounts of data. MongoDB is a relational database built on the architecture of collections and documents rather than tables and rows.


In MongoDB, the rows don’t require to have a schema specified beforehand. Rather, the fields can be generated on the fly. The data model within MongoDB enables you to express hierarchical relationships, store arrays, and other more complicated structures. 


Now let us come to the SQL vs MongoDB difference….


Significant Differences between SQL and MongoDB


Now below, we will discuss the difference between both SQL and MongoDB in detail.


Data Representation


In the case of MongoDB, data are represented as JSON documents, on the other hand, in SQL, data are represented as rows and tables.

Data would like this in MySQL:


In MongoDB, it looks as follows:


MongoDB Document


name: ”John cena”,

age: 30,

contact: {

mobile: ”+91-0001112223”,

home_address: ”New York street”



Data Embedding


MySQL doesn’t give any choice for data nesting or data embedding. You can utilize JOINs, but they might end up in larger tables with redundant fields. JOINs can also be performance-intensive and time-consuming.

MongoDB enables you to insert related data. You also can reference data from different documents if you know the document may develop too much. An example includes:


    id: 14,

    name: ‘Maria’,

    age: 26,

    address: {

        City: ‘New street,

        Street: ‘New York’,

        Zip_code: 6666




Query Language


SQL uses MySQL, on the other hand, MongoDB uses MQL, the MongoDB query language. We will compare some common database operations on the Employee table in this section.

  • Selection of data in MySQL

Select * from representative;

  • Insertion of data in MySQL

INSERT INTO representative (representative_id, department, status)

VALUES (22, ‘Sales’, ‘Active’);

  • Updation of data in MySQL

UPDATE representative SET department = ‘Finance’ WHERE representative_id = 15;

  • Selection of data in MongoDB*


  • Insertion of data in MongoDB

db.representative.insert ({representative_id:’15’, department.Sales’, status:’Active’})

  • Updation of data in MongoDB



Index Optimization


Both SQL and MongoDB utilize indexes for optimization. If MySQL doesn’t find a suitable index for a query, it examines the complete table, and MongoDB explores every document in a group if there are no indexes.


Database Deployment


For many operating systems, MySQL has binaries, so it can be extended natively, whereas MongoDB is more adapted to distributed conditions.


Speed and Performance


Since the NoSQL database is MongoDB, it is more lasting than MySQL.


Data Grouping


MongoDB reserves documents that refer to a single class or collection in a group, and MySQL reserves rows of related types in a table.




MySQL supports master-slave and master-master replication enabling you to repeat from different master databases in parallel. Whereas MongoDB helps built-in sharding, duplication, and auto-elections.Sharding provides horizontal scaling, and auto-elections allow you to set up secondary databases that take over if your primary database crashes.




MySQL has a privilege-based security paradigm, in which users are authenticated and granted rights over certain database activities. 

It employs encoded connections between servers and clients at the transport layer. MongoDB uses Role-based authentication with flexible rights. It encrypts and decrypts data using Transport and Socket Layers, guaranteeing only authorized users access the database.




MySQL is vertically scalable, which means you can extend the load on a particular server by expanding RAM or CPU specs. MongoDB is horizontally scalable, which means you can generate a MongoDB cluster with various servers by combining more servers to your database.


Final Decision

When you are choosing between MongoDB or SQL, it’s hard to decide the winner, as both cater to different areas. Your decision will depend on your project goals and requirements. Above, we have given some of the factors you can consider while differentiating SQL vs MongoDB. SQL is an immeasurable choice if You just began your company, your database is not scaled much, or you have a high transaction rate. Also, if You want more reliable support, then SQL is best (click the link to get the best SQL assignment help). People have been using SQL for a long time so, it’s a lot simpler to get solutions to frequent problems. SQL is a great option if you work with a legacy application asking for multi-row transactions with a clear schema. When you are working with an uncertain schema and want to lessen the cost of schema migration
