In a logical multilayer architecture for an information system with an object-oriented design, the following four are the most common: Presentation layer (a.k.a. UI layer, view layer, presentation tier in multitier architecture) Application layer (a.k.a. service layer [8] [9] or GRASP Controller Layer [10])
Enterprise architecture frameworks, such as TOGAF and the Zachman Framework, usually distinguish between different enterprise architecture layers. Although terminology differs from framework to framework, many include at least a distinction between a business layer , an application (or information ) layer , and a technology layer .
Network architecture is the design of a computer network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
The application layer is the layer of the OSI model that is closest to the end user, which means both the OSI application layer and the user interact directly with a software application that implements a component of communication between the client and server, such as File Explorer and Microsoft Word.
In software object-oriented design, a layer is a group of classes that have the same set of link-time module dependencies to other modules. [1] In other words, a layer is a group of reusable components that are reusable in similar circumstances. In programming languages, the layer distinction is often expressed as "import" dependencies between ...
In telecommunications, a layered system is a system in which components are grouped, i.e., layered, in a hierarchical arrangement, such that lower layers provide functions and services that support the functions and services of higher layers.
The Java Platform, Enterprise Edition architecture is a layered reference architecture which provides a template solution for many enterprise systems developed in Java. Examples of implementing frameworks include Glassfish and Wildfly. The IBM Insurance Application Architecture [3] is a reference architecture for the Insurance domain.
The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode. It is a preemptive , reentrant multitasking operating system, which has been designed to work with uniprocessor and symmetrical multiprocessor (SMP)-based computers.
