N-tier architecture is an application structure wherein the work for the servers (service- providers) and clients (service requesters) are separated to ease developers in developing web applications. The structure includes a number of levels arranged one upon another and each level is allocated for distinct set of task. Also known as multi-tier architecture, this client-server architecture includes separate sections for presentation, application processing and data management processes.
It is often seen that both clients and servers undergo communication over a common computer network but by using separate hardware. The computing system of the service providers (server) host a number of programs to be shared with the clients. On the contrary, a client may not share any of its personal resources with the server machine and instead, may send incoming request for services from the server. Here lies the use of N-tier client-server architecture which lays down a model for web developers to create customized web applications as per the specific business requirements.
A major benefit of using N-tier architecture is that web developers can easily separate the applications into multiple tiers and can modify them rather than rewriting the entire application. Furthermore, the applications are loosely connected with each other and changes made in one application do not hamper performance of others.
Generally, web application developers use 3-tier application, which includes a programming tier, a logic tier and a data tier. The user interface programming tier translates task to help user easily understand the information related to services. This topmost level of the application structure interacts with other tiers by providing results to all other tiers in the computing network. The logic tier controls the functioning of the application by processing commands, evaluating and calculating specific data. The information from programming layer is later stored in the database servers of the data tier. The stored information is then transferred back to the logic tier for further processing and ultimately to the user's computer system.
Web applications meant for e-commerce websites are popular examples of N-tier client-server architecture. If you want to have web-application created out of using N-tier application program, then you can seek assistance from software development companies. There are a few software development companies which have skilled engineers to provide flawless combination of various layers for N-tier client-server architecture. You can also hire some offshore web developers who are experienced in handling database including Oracle, SQL Server, MySQL and MS Access.
So, spare out some time to find reliable software development companies and hire web developers to get web applications created out of N-tier client-server architecture.
