Being weighed down by some of the disadvantages of client-server application forced the developers to turn to other alternatives. The remarkable success like J2EE framework gave birth to what is now known as N-Tier architecture application development which offered added advantages like division of labour, deployment of distributed applications etc. N-Tier architecture application development is in reality an extension of previous architectures like Client-Server, Thin-Client etc. The fundamental principle of the N-Tier architecture application development is to promote re-use through the planned use of partitioned business logic in its own distinct re-usable layer.

N-Tier architecture application development has contributed greatly to the development of web-based applications and distributed computing. The ability to input, process, store, and access data anytime, anywhere and on any device is powering today's e-Businesses. The advent of J2EE and .NET framework has provided standard modular components and total service bouquets to these modules. Using J2EE for N-Tier application development involves breaking the two-tier architecture into multiple tiers. An N-Tier application development can provide separate layers for each of the following services - Presentation Layer, Dynamic Presentation, Business logic, and Data base access. A browser takes care of the presentation layer, and JSP / Servlet / XML / SOAP and XSL take care of the dynamic presentation, Session EJB takes care of the business logic and Entity beans take care of the data access using JDBC.
