What is meant by 3-Tier architecture?

In 3-tier Client/Server systems, the application logic (or process) lives in the middle tier and it is separated from the data and the user interface. In theory, the 3-tier Client/Server systems are more scalable, robust and flexible.Example: TP monitor, Web.

A special type of client/server architecture consisting of three well-defined and separate processes, each running on a different platform: 1. The user interface, which runs on the user's computer (the client). 2. The functional modules that actually process data. This middle tier runs on a server and is often called the application server. 3. A database management system (DBMS) that stores the data required by the middle tier. This tier runs on a second server called the database server.
