What are the 3 layers of web applications?

The architecture of a website-based application or web application includes 3 key layers that need to be effectively developed. Below we will take a detailed look at each of the main layers:

Layer 1 – Presentation

Layer 2 – Business

Level 3 – Data


The presentation layer of the mobile application architecture shows how well the application is equipped for the best user experience or UX design. It includes design elements such as visual, audio, user interface (UI) and navigation, creating an aesthetic that the user will appreciate. The presentation layer of the mobile app includes unique design elements such as colors, notification sounds, avatars, media and intuitiveness. The presentation layer of a mobile web application also affects how well it meets the needs of end users. In fact, the presentation layer creates a unique look and feel of the architecture of your mobile application.


The business layer of the mobile application architecture focuses on the internal processes of the mobile application. This layer consists of a logical sequence and a data stream of a mobile application. Aspects of the business layer include data security and payment gateway systems. The business layer also includes the logical processing of the workflow and how the mobile application stores or logs the user’s history.


The data layer focuses on managing the information received by the mobile application. It includes data access elements, data elements, and functions that provide mobile application processes, such as data validation. The data layer ensures the accuracy of the stored or processed data during the operation of the mobile application
