  2. Multitier architecture - Wikipedia

    en.wikipedia.org/wiki/Multitier_architecture

    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])

  3. Layer (object-oriented design) - Wikipedia

    en.wikipedia.org/wiki/Layer_(object-oriented_design)

    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 ...

  4. GRASP (object-oriented design) - Wikipedia

    en.wikipedia.org/wiki/GRASP_(object-oriented_design)

    It should not do much work itself. The GRASP Controller can be thought of as being a part of the application/service layer [4] (assuming that the application has made an explicit distinction between the application/service layer and the domain layer) in an object-oriented system with common layers in an information system logical architecture.

  5. Hexagonal architecture (software) - Wikipedia

    en.wikipedia.org/wiki/Hexagonal_architecture...

    The hexagonal architecture, or ports and adapters architecture, is an architectural pattern used in software design. It aims at creating loosely coupled application components that can be easily connected to their software environment by means of ports and adapters. This makes components exchangeable at any level and facilitates test automation ...

  6. Bridge pattern - Wikipedia

    en.wikipedia.org/wiki/Bridge_pattern

    The bridge pattern is often confused with the adapter pattern, and is often implemented using the object adapter pattern; e.g., in the Java code below. Variant: The implementation can be decoupled even more by deferring the presence of the implementation to the point where the abstraction is utilized.

  7. C Sharp (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.

  8. Three-layer architecture - Wikipedia

    en.wikipedia.org/wiki/Three-layer_architecture

    The Three-Layer Architecture is a hybrid reactive/deliberative robot architecture developed by R. James Firby [1] that consists of three layers: a reactive feedback control mechanism, a reactive plan execution mechanism, and a mechanism for performing time-consuming deliberative computations.

  9. Dynamic Language Runtime - Wikipedia

    en.wikipedia.org/wiki/Dynamic_Language_Runtime

    This architecture is backed by the idea that the number of elementary language constructs that would have to be implemented on the generic stack should be inherently limited. [20] The DLR dynamically generates code corresponding to the functionality expressed by these nodes. The compiler for any dynamic language implemented on top of the DLR ...
