- Presentation tier. The presentation tier is the user interface and communication layer of the application, where the end user interacts with the application.
- Application tier. The application tier, also known as the logic tier or middle tier, is the heart of the application. In this tier, information that is collected in the presentation tier is processed - sometimes against other information in the data tier - using business logic, a specific set of business rules.
- Data tier. The data tier, sometimes called database tier, data access tier or back-end, is where the information that is processed by the application is stored and managed.
- Tier versus layer. In discussions of three-tier architecture, layer is often used interchangeably – and mistakenly – for tier, as in 'presentation layer' or 'business logic layer'.
A 3-tier application architecture is a client-server implementation that uses a presentation tier, application tier and data tier to organize app design.

Three-Tier Architecture is an is an well established software application design pattern which will organizes the application in the three logical and physical computing tiers as following: 1. Presentation Tier 2. Application Tier 3. Data Tier
Presentation Tier
It is the user interface and topmost tier in the architecture. Its purpose is to take request from the client and displays information to the client. It communicates with other tiers using a web browser as it gives output on the browser. If we talk about Web-based tiers then these are developed using languages like- HTML, CSS, JavaScript.
Application Tier
It is the middle tier of the architecture also known as the logic tier as the information/request gathered through the presentation tier is processed in detail here. It also interacts with the server that stores the data. It processes the client’s request, formats, it and sends it back to the client. It is developed using languages like- Python,Java, PHP, etc.
Data Tier
It is the last tier of the architecture also known as the Database Tier. It is used to store the processed information so that it can be retrieved later on when required. It consists of Database Servers like- Oracle, MySQL,DB2, etc. The communication between the Presentation Tier and Data-Tier is done using middle-tier i.e. Application Tier.
Web application will have the same tiers as the three architectures but only difference is that they are with different names. 1. Web Server: Web server is an presentation tier of an three-tier architecture which servers as an presentation tier or UI (User Interface) tier. This content can be static or dynamic based on there requirement such as an ...
Three Tier Architecture is the widely used for the application development there are some other architecture as mentioned below.
Logical separation is maintained between Presentation Tier, Application Tier, and Database Tier.Enhancement of Performance as the task is divided on multiple machines in distributed machines and moreover, each tier is independent of other tiers.Increasing demand for adding more servers can also be handled in the architecture as tiers can be scaled independently.Developers are independent to update the technology of one tier as it would not impact the other tiers.The Presentation Tier cannot communicate directly with Database Tier.Complexity also increases with the increase in tiers in architecture.There is an increase in the number of resources as codebase, presentation code, and application code need to be maintained separately.Learn about the three-tier client-server architecture, a common type of multi-tier architecture in distributed systems. It consists of presentation, application, and data tiers that are developed and maintained independently.
May 13, 2024 · One of the most prevalent patterns seen in modern software architecture is the 3-tier (or three-tier) architecture. This model structures an application into three distinct tiers: presentation (user interface), logic(business logic), and data (data storage).
