what is a three tier framework? what tiers are included in this framework? what are the functions of each tier

Expert Solution

A 3-tier application architecture is a modular client-server architecture that consists of a presentation tier, an application tier and a data tier. The data tier stores information, the application tier handles logic and the presentation tier is a graphical user interface (GUI) that communicates with the other two tiers.

Three tiers, that are included in this framework,,

Presentation Tier
Application Tier
Data Tier

Presentation tier - This tier, which is built with HTML5, cascading style sheets (CSS) and JavaScript, is deployed to a computing device through a web browser or a web-based application. The presentation tier communicates with the other tiers through application program interface (API) calls.

Application tier - The application tier, which may also be referred to as the logic tier, is written in a programming language such as Java and contains the business logic that supports the application’s core functions.

Data tier - The data tier consists of a database and a program for managing read and write access to a database. This tier may also be referred to as the storage tier and can be hosted on-premises or in the cloud.
