Blackboard (design pattern) In software engineering, the blackboard pattern is a behavioral design pattern [1] that provides a computational framework for the design and implementation of systems that integrate large and diverse specialized modules, and implement complex, non-deterministic control strategies. [2] [1]
A blackboard system is an artificial intelligence approach based on the blackboard architectural model, where a common knowledge base, the "blackboard", is iteratively updated by a diverse group of specialist knowledge sources, starting with a problem specification and ending with a solution. Each knowledge source updates the blackboard with a ...
An architectural pattern is a general, reusable resolution to a commonly occurring problem in software architecture within a given context. The architectural patterns address various issues in software engineering , such as computer hardware performance limitations, high availability and minimization of a business risk .
An Introduction to Software Architecture describes it as such "We are still far from having a well-accepted taxonomy of such architectural paradigms, let alone a fully-developed theory of software architecture. But we can now clearly identify a number of architectural patterns, or styles, that currently form the basic repertoire of a software ...
Space-based architecture. A Space-based architecture ( SBA) is an approach to distributed computing systems where the various components interact with each other by exchanging tuples or entries via one or more shared spaces. This is contrasted with the more common Message queuing service approaches where the various components interact with ...
Adapter pattern. In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. [1] It is often used to make existing classes work with others without modifying their source ...
Architectural styles are reusable 'packages' of design decisions and constraints that are applied to an architecture to induce chosen desirable qualities. There are many recognized architectural patterns and styles, among them: Blackboard; Client-server (2-tier, 3-tier, n-tier, cloud computing exhibit this style) Component-based; Data-centric
Facade pattern. The facade pattern (also spelled façade) is a software design pattern commonly used in object-oriented programming. Analogous to a façade in architecture, it is an object that serves as a front-facing interface masking more complex underlying or structural code. A facade can: improve the readability and usability of a software ...
