An application for which the component application programs are distributed between two or more interconnected processors.
A combination of clients and servers that communicates through well-defined remote interfaces.
An application that runs on two or more networked computers.
An application built from interacting remote objects.
An application that has two parts - a front-end to run on the client computer and a back-end to run on the server. In distributed computing, the goal is to divide the computing task into two sections. The front-end requires minimal resources and runs on the client?s workstation. The back-end requires large amounts of data, number crunching, or specialized hardware and runs on the server. Recently, there has been much discussion in the industry about a three-tier model for distributed computing. That model separates the business logic contained in both sides of the two-tier model into a third, distinct layer. The business logic layer sits between the front-end user interface layer and the back-end database layer. It typically resides on a server platform that may or may not be the same as the one the database is on. The three-tier model arose as a solution to the limits faced by software developers trying to express complex business logic with the two-tier model.
An application made up of distinct components running in separate runtime environments, usually on different platforms connected through a network. Typical distributed applications are two-tier (client/server), three-tier (client/middleware/server), and n-tier (client/multiple middleware/multiple servers).
A program written so that the processing can be divided across multiple computers over a network. Typically, a distributed application is divided into presentation, business logic, and data store layers, or tiers. See also client tier, middle tier, data source tier.
In message queuing, a set of application programs that can each be connected to a different queue manager, but that collectively constitute a single application.
A program designed to run on more than one computer, typically with functionality separated into tiers such as client, service, and data store.
