N-tier
The most widespread use of "multi-tier architecture" refers to three-tier architecture.
Three-tier architecture has the following three tiers:
Presentation tier
This is the topmost level of the application. The presentation tier displays information related to such services as browsing merchandise, purchasing, and shopping cart contents. It communicates with other tiers by outputting results to the browser/client tier and all other tiers in the network.
Business Logic
- coordenaits the application
- proccess commands
- makes logical desicions and evaluations
- preforms calculations
- controls an application’s functionality by performing detailed processing
- security processes
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.
