Now, it’s often to heard in programming world that a developer build application in multi tiered application. What is the meaning of multi tiered application? This is it..
In a multi-tiered application, the functionality of the application is separated into isolated functional areas, called tiers. Typically,multi-tiered applications have a client tier, a middle tier, and a data tier (often called the enterprise information systems tier). The client tier consists of a client program that makes requests to the middle tier. The middle tier’s business functions handle client requests and process application data, storing it in a permanent datastore in the data tier.
Java EE application development concentrates on the middle tier to make enterprise application management easier,more robust, and more secure. This article is adopted from an ebook that published by Oracle, which titled Your First Cup: An Introduction to the Java EE Platform.
