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.
Angular is a development platform that focus to make Web Development feel effort-less, Aim on developer productivity, speed and testability. Angular puts you in control over scalability Achieve the maximum speed possible on the Web Platform today, and take it further, via Web Workers and server-side rendering. Meet huge data requirements by building data models on RxJS, Immutable.js or another push-model. Applications built with Angular can be deployed to mobile devices and desktops as websites and native applications. Angular is used in public-facing applications and sites such as Google Cloud Platform and AdWords, as well as many internal tools. Build features quickly with simple, declarative templates.Get immediate Angular-specific help and feedback with nearly every IDE and editor.Extend the template language with your own components and use a wide array of existing components. All this comes together so you can try to aim on building amazing applications rather than trying to make the code work.
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.

MEAN Stack is one of the most popular Technology Stack. The MEAN stack is JavaScript-based framework for developing web applications. It is used to develop a Full Stack Web Application. MEAN is named after MongoDB, Express, Angular, and Node, the four key technologies that make up the layers of the stack.it is a Stack of different technologies, all of these are based on JavaScript language.
Mean Stands For
M – MongoDB
E – Express
A – Angular
N – Node.js
This stack leads to faster development as well as the deployment of the Web Application.
As we can say, the MEAN stack comprises,MongoDB, Express, Angular, Node.js this all are free & open-source stacks. The stack development is cost effective. their communities offer ready-to-use boilerplate codes that development can facilitate of incredible UIs.
- ExpressJs will connect MongoDB and receives the data
- MongoDB will be fetched the requested data and return that request to the Express. js
- Angular.js display the result fetched from MongoDB to the client.
- A request is made by the client who is further processed by the Angular.js.
- Afther that request moves to Node.js which will forward the request
- Node.js will return the request to the client.
Its Helps in development of applications on fast and rapid base. Only single uniform language throughout your stack developmentAllows creating a simple open source and build robust and maintainable solutions.
Uses very low memory footprint/overhead.
MEAN is full stack JavaScript which is 100% free.
MEAN makes code isomorphic.
