3 Tier Architecture:
The 3 tier architecture consist of 3 layers namely:
- Presentation Layer:
- Application Layer
- Data Layer
Presentation Layer:
It consist of the User interface layer. It is actually a content like graphics which is presentable to user in web application or web browser.
Application Layer:
It actually represent the capability of application in form of business logic.
Data Layer:
It is actually represent access of data via call by application layer. It consist of database storage and retrieval.
For Example, Technologies used to build respective Layer as below:
- Presentation Layer: UI based technologies such as HTML5, CSS, Javascript
- Application Layer: Middleware or Business Logic based technologies such as Python, .NET, Java
- Data Layer: Data storage and retrieval based technologies such as MySQL, PostgreSQL, MongoDB.
Layer Deployment:
Presentation Layer are deployed on web browser, desktop, mobile which is using the web server.
Application Layer are deployed on application server or cloud.
Data Layer are deployed on premise of organisation such as data centre or cloud.
