Multi-tier Architecture
From RemObjects Software
Multi-tier architecture, or n-tier architecture is a client-server architecture where the parts are separated in multiple application. Generally the term is used in cases that involve more than 2 tiers, usually 3.
Two-Tier architecture
Two-Tier is the client/server model, where a client talks directly to a remote database server. The logic is usually placed in the client.
Three-Tier architecture
In a three-tier architecture there is an extra layer between the client and the server, the application layer.
This layer usually handles the logic, the security, and abstracts away the underlying database(s). Data Abstract provides this functionality.
