MongoDB vs. MySQL: Sure-Fire Databases to Uncover your Project’s True Value

This includes companies like Airbnb, Uber, Netflix, Dropbox, Pinterest, Twitter, Slack, Shopify, LinkedIn and many more.

• The database of MySQL consists of tables and rows.
• Additionally, the schema helps define the values to be represented by a specific data type.

• In MongoDB, all the data is stored in BSON document and the data interchange format that provides a binary representation of JSON-like documents with varied structures.
• Related data is stored together which eventually increases the efficiency of the program.
• It lacks schema, enabling developers to create documents without defining the structure.
• All the documents are modifiable and uniquely structured.
• It is scalable enough to accommodate new entries and adding or updating existing functionalities.
• Keys can be re-used within the document.
• MongoDB data model allows making use of complex data structures like hierarchical relationships, data arrays, and complex structures.

Encrypted databases operate on top of commodity DBMS so that even if the underlying system is compromised the attack is not able to obtain the data. But partial information in the form of plaintext is often leaked.

Sharding allows for horizontal scaling, which is difficult to implement in MySQL, by making use of replica sets to create multiple copies of the data.

• Very easy to learn and use.
• Makes use of structured queries to retrieve information and store records in a database.

• Storing data in documents speeds up the data retrieval process.
• MongoDB allows sharding of data across the nodes in a cluster to ensure that there is no single-point-of-failure in the database server.
• MongoDB allows for not just a primary index but also for a secondary index which is important in many applications.
• MongoDB caches a lot of data to allow faster retrieval of the query results.
• There are various features on MongoDB (Ad-hoc queries, Indexing, Replication, Load balancing, File storage, Aggregation, Server-side JavaScript execution, capped collections, etc.) that make it a very user-friendly database.

It also does not have a provision for stored procedures. So if portability is required Internal Data Access API should be used.

C:\Users\Your Name>npm install MySQL

To manipulate the MySQL database:

var mysql = require(‘mysql’);

Create Connection

var mysql = require(‘mysql’);

var con = mysql.createConnection({
host: “localhost”,
user: “yourusername”,
password: “yourpassword”
});

con.connect(function(err) {
if (err) throw err;
console.log(“Connected!”);
});

1.  Download and install the MongoDB package:

C:\Users\Your Name>npm install MongoDB

var con = mysql.createConnection({
host: “localhost”,
user: “yourusername“,
password: “yourpassword“
});

con.connect(function(err) {
if (err) throw err;
console.log(“Connected!”);
con.query(“CREATE DATABASE mydb“, function (err, result) {
if (err) throw err;
console.log(“Database created”);
});
});

var con = mysql.createConnection({
host: “localhost”,
user: “yourusername“,

  database: “mydb”
});

con.connect(function(err) {
