Hi What is the reason of using three - tier architecture in application? What is it's benefit? Thanks.

Hi Alok 3-Tier (N-Tier) Architectures make application more robust because there is no single point of failure. Also tiers function with relative independence. For example if a business changes database vendors they just have to replace the data tier and adjust the integration tier to any changes that affect it. The business logic tier and the presentation tier remain unchanged. Likewise if the presentation layer changes this will not affect the integration or data layer. For more information ref.
