Software Development >N-Tier Development

N-Tier architecture refers to the architecture of an application that has at least 3 "logical" layers -- or parts -- that are separate. Each layer interacts with only the layer directly below, and has specific function that it is responsible for.  An n-Tier application usually has three tiers, and they are called the presentation tier, the business tier and the data tier. 

Our great experience in Client/Server helped us develop N-tier applications specifically large projects. The distributed architecture helps typically for large applications. We built strong expertise for the middle ware i.e; business logic implementation in Microsoft's hot technology COM/DCOM to provide complete, time efficient and scalable solution to our clients. 

The client/server applications are not scalable, are difficult to maintain and enhance due to tight coupling between the presentation layer, business logic and the database access. Overall the two tier applications are not scalable and are not suitable for Internet based applications. With the growing popularity of J2EE framework, the development of an n-tier application became easier and all the negatives of a two-tier application were well taken care. A J2EE framework provides standardized modular components and a complete set of services to those components. More-over application behavior such as security and multithreading are handled automatically.
