N-Tier Architecture
Short introduction to Multi-Tier Architecture
Multi-tier architecture (often referred to as n-tier architecture) or multilayered architecture is a client–server architecture in which presentation, application processing, and data management functions are physically separated. Using an N-tier architecture, web developers can create modular applications.
Common layers
In a multilayered architecture the most common used layers are:
Presentation layer - the visual part of a web application
Application layer - the server-side of a web application
Database layer - the persistence layer where information is saved and updated
Presentation layer
This layer handles the user interaction. This part of the application is usually built-in HTML and Javascript in various technologies and frameworks:
React - the popular Javascript framework built by Facebook
Vue.js - The Progressive JavaScript Framework
Application layer
Represents the server-side of the application and can be developed in many programming languages:
Php (the most popular server-side language ) using Laravel, CodeIgniter
Database layer
The majority of web apps requires a type of storage to save the relevant data:
MySql - the popular open-source database engine
SQLite - the lite version of MySql
MongoDB - a document-based engine
Common Architectures
In web development the most used architectures are:
Single Tier architecture
The web application is served only once by the server, and runs entirely on the client-side
Two Tier architecture
Sometimes named Full-Stack architecture
