What Is Docker?
Docker is a Containerization platform which packages your application & all its dependencies together in the form of
Containers, to ensure that your application works seamlessly in any environment be it Development/ Test/ Production.
• RAM consumed by containers is << RAM consumed by VMs.
• Easily run applications by packaging them into containers.
• Containers are light-weight; can be easily shared via Docker Hub.

How Do We Create Docker Containers?
Docker files are used to build a Docker image & that image will also contain all the project codes.
The same Docker image can be used to spin ‘n’ no of containers, each with modifications to the underlying image.
This final image can then be uploaded to Docker Hub & shared with other collaborators for testing/ deployment.

What Is Docker Compose?
Docker Compose is used to run multi-container applications.
Each container will run a stand-alone application and it can communicate with other containers present in the same host.
Example: MEAN Stack Application [MongoDB, ExpressJS, Angular & NodeJS] using different containers.

What Is A MEAN Stack Application?
MEAN is a Full-stack JavaScript Solution that helps you build fast, robust, and maintainable
production web applications using MongoDB, Express, Angular and Node.js.

➢ Data Warehouse is like a relational database designed for analytical needs.
➢ It functions on the basis of OLAP (Online Analytical Processing).
➢ It is a central location where consolidated data from multiple locations (databases) are stored.
