can anybody please tell me the difference
between 2-tier architecture and 3-tier

Hi linuskh,

In simple words, 2-tier architecture consists of a server and a client and a 3-tier archi. consists of a server, a client and a database layer. Client requests from server, server requests or store data in database , database returns data to server which in turn is returned to client by server.

The problem with 2-tier archi. is server stores data and it gives rise to data integrity issues when multiple clients simultaneously request server to perform tasks.
