MongoDB is a cross-platform, document oriented database that provides, high performance, high availability, and easy scalability. MongoDB is written in C++. MongoDB is an open-source document database and leading NoSQL database. Mongo Database is a physical container for collections.Each database gets its own set of files on the file system. MongoDB works on concept of collection and document.Collection is a group of MongoDB documents. It is the equivalent of an RDBMS table. A collection exists within a single database. Collections do not enforce a schema. Documents within a collection can have different fields. Dynamic schema means that documents in the same collection do not need to have the same set of fields or structure, and common fields in a collection’s documents may hold different types of data.all documents in a collection are of similar or related purpose.A document is a set of key-value pairs. Documents have dynamic schema.
MongoDB Advantages Over The RDBMS
- Structure of a single object is clear.
- Schema less − it is a documentation database in which one collection holds different documents. number of fields, size of the document and content can differ from one document to another.
- Deep query-abilities.
- MongoDB supports dynamic queries on documents using a document-based query language that’s nearly as powerful as SQL.
- No complex joins.
- Tuning.
- Easy of scale-out − MongoDB is easy to scale.
- Conversion/mapping of application objects to database objects not needed.
- Uses internal memory for storing the(windowed) set of working, faster enabling access of data.
Use of MongoDB?
- Document store in a JSON document form style.
- Replication and Heigh Ability
- Rich Queries and Auto Sharding
- Mostly use for Big Data
- Content management and delivert
- Mobile and Social infrastructure
- User Data Management
- Data Hub
Express is a minimal and flexible Node.js web application framework that provides a robust set of features to development of web and mobile applications. It’s Focus onSuper-high test coverage, high performance, View system supporting 14+ template engines, HTTP helpers (redirection, caching, etc), Content negotiation, Executable for generating applications quickly.It facilitates the rapid development of Node based Web applications. Express provides a thin layer of fundamental web application features, without obscuring Node.js features that you know and love. Express use HTTP utility methods and middleware disposal, creating a robust API is quick and easy way.
React is a tool for building UI components.React makes it painless to create interactive UIs.Build encapsulated components that manage their own state, then compose them to make complex UIs.React uses an HTML-in-JavaScript syntax, which is called JSX (JavaScript and XML). HTML and JavaScript Both will help you to learn JSX with familiarity, and better identify whether bugs in your applications are related to JavaScript or to the more specific domain of React. React creates a VIRTUAL DOM in memory. Instead of manipulating the browser’s DOM directly, React creates a DOM virtualy in memory, where it does all the necessary manipulating, before changes in the browser DOM.React, sometimes referred to as a frontend JavaScript framework, is a JavaScript library created by Facebook.
Node.js is a server-side platform built on Chrome’s JavaScript runtime for easily building fast and scalable network applications. Node.js was developed by Ryan Dahl in 2009 and its latest version is v0.10.36. The definition of Node.js as supplied by its official documentation.Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux.Node.js also provides a rich library of various JavaScript modules which simplifies the development of web applications.

MERN Stack is a Javascript Stack that is used for easier and faster deployment of full-stack web applications. It comprises several open-source components such as MongoDB, React, Node.js, and Express.js. MERN is one of several variations of the MEVN (MongoDB, Express, Vue, Node), Other . include Variation of the MEAN(MongoDb Express Angular Node) where he traditionalAngular.js frontend framework is replaced with React.js and really any frontend JavaScript framework can work.
Supports MVC architecture for a smooth development process.
As it is a JavaScript stack, developers can only be pro in JSON and JavaScript.
Covers complete web development cycle from frontend to backend with JS.
It is an open-source framework backed by community support.
as an extensive built-in suite to test tools.
If you are looking for a sophisticated UI yet simple enough to render an app, go for the MERN framework. It generates a frame to display on the screen and ensure seamless user interaction.
