The blackboard architecture is a flexible and powerful expert system framework. It represents a general approach to problem solving that is useful in many domains of applications especially in the area of intelligent control.
In software engineering, the blackboard pattern is a behavioral design pattern 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.
Advantages of Blackboard Architecture Style Blackboard architecture style provides concurrency which allows knowledge sources to work in parallel. This architecture supports experimentation for hypotheses and reusability of knowledge source components.
A blackboard system consists of three components: 1) Knowledge sources (KSs); 2) Blackboard; 3) Control component. Knowledge sources are independent modules that contain the knowledge needed for problem solving.
A repository architecture consists of a central data structure (often a database) and a collection of independent components which operate on the central data structure Examples of repository architectures include blackboard architectures, where a blackboard serves as communication centre for a collection of knowledge ...
Software architecture is, simply, the organization of a system. This organization includes all components, how they interact with each other, the environment in which they operate, and the principles used to design the software. In many cases, it can also include the evolution of the software into the future.
Architectures must have both form and function and it is a good test of an architecture to measure its elegance. An architecture that is well designed will tend to be elegant and have a simplicity of form that will be obvious to those that take the time study it.
Reference architecture or model provides a common vocabulary, reusable designs, and industry best practices that are used as a constraint for more concrete architectures. Typically, reference architecture includes common architecture principles, patterns, building blocks, and standards.
In Repository Architecture Style, the data store is passive and the clients (software components or agents) of the data store are active, which control the logic flow. The participating components check the data-store for changes. The client sends a request to the system to perform actions (e.g. insert data).
The Pipe and Filter is an architectural pattern for stream processing. It consists of one or more components called filters. These filters will transform or filter data and then pass it on via connectors called pipes.
A software architecture introduces constraints on implementation and restricts design choices. This reduces the complexity of a software system and prevents developers from making incorrect decisions.Aug 30, 2020
Data flow architecture reduces development time and can move easily between design and implementation. It has main objective is to achieve the qualities of reuse and modifiability. In data flow architecture, the data can be flow in the graph topology with cycles or in a linear structure without cycles.
