The presentation layer is the outermost layer of the technology stack and is responsible for creating the user interface (UI) of the software application. Users directly interact with this layer of the stack, so its design and functionality greatly influence the user experience. The primary objectives of the presentation layer include:

User interface design

This layer determines how the application looks and feels to users. It involves creating visually appealing layouts, color schemes, typography, and other design elements to ensure an intuitive and user-friendly interface.

HTML (Hypertext Markup Language)

HTML is the foundation of web-based user interfaces. It structures content by defining elements like headings, paragraphs, images, buttons, and links. It establishes the basic layout and content hierarchy of a web page.

CSS (cascading style sheets)

CSS is used to control the presentation and styling of HTML elements. It allows developers to apply colors, fonts, margins, padding, and positioning to create consistent and aesthetically pleasing designs.


JavaScript adds interactivity and dynamic behavior to web pages. It enables features like animations, form validation, real-time updates, and user interactions. JavaScript frameworks like React, Angular, and Vue.js provide tools to build complex UIs efficiently.

Application layer

The application layer resides beneath the presentation layer and is responsible for handling the core logic and functionality of the software application. This layer processes user input, manages data, and performs computations to achieve the application's goals.

Key aspects of the application layer include:

Logic & processing

This layer implements the business logic of the application. It defines how data is processed, transformed, and manipulated to achieve specific tasks or functions.

Programming languages

Programming languages like Python, Java, Ruby, C#, and others are used to write the code that makes the application function. The choice of programming language depends on factors like the project's requirements and the development team's expertise.


Frameworks are pre-built sets of tools and libraries that streamline development by providing standardized solutions to common challenges. Examples include Django and Flask for Python, Ruby on Rails for Ruby, and Spring Boot for Java.
