3-Tier Architecture vs MVC Software Architecture
« on: November 27, 2010, 11:17:20 AM »
3-Tier software architecture is client-server model where the presentation, the application processing, and the data management are logically separate processes. On web technologies, for example we have the Client (Presentation), Web server (Logical), and Database (Data Management) as the 3-tier. 2 -tier typically involves an architecture without data management where only the presentation and the logic is used.

Presentation tier:This is the topmost level of the application. The presentation tier displays information to and fro the Application Logic. It communicates with other tiers by outputting results to the browser/client tier and all other tiers in the network.

Application tier: (business logic, logic tier, data access tier, or middle tier). The logic tier is pulled out from the presentation tier and, as its own layer, it controls an application’s functionality by performing detailed processing.

Data tier: : This tier consists of database servers. Here information is stored and retrieved. This tier keeps data neutral and independent from application servers or business logic. Giving data its own tier also improves scalability and performance.
