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.
Structure. The blackboard model defines three main components: blackboard - a structured global memory containing objects from the solution space. knowledge sources - specialized modules with their own representation.
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.
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.
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.
If a new building is absolutely necessary, it should be good. It should work well and answer all codes, but that is only the beginning point. It should use minimal amounts of energy both in construction and in use. It should offer spaces that do not imprison and pigeonhole us.
The blackboard was originally designed as a methodology in order to handle complex, ill-defined problems. First famous example is the Hearsay II speech recognition system. More recent example the PLAN component of the mission Control System for RADASAT-1 is a blackboard system.
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.
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
Explanation: Software architecture is a structure or structure of systems, which comprise software components, external visible properties of those components and relationship among them.
A blackboard (also known as a chalkboard) is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate, known, when used for this purpose, as chalk. Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone.
Blackboard is a Web-based course-management system designed to allow students and faculty to participate in classes delivered online or use online materials and activities to complement face-to-face teaching.
The layered architecture style is one of the most common architectural styles. The idea behind Layered Architecture is that modules or components with similar functionalities are organized into horizontal layers. As a result, each layer performs a specific role within the application.
A reference architecture is a document or set of documents that provides recommended structures and integrations of IT products and services to form a solution. The reference architecture embodies accepted industry best practices, typically suggesting the optimal delivery method for specific technologies.
The infrastructure layer (also known as the persistence layer) contains all the classes responsible for doing the technical stuff, like persisting the data in the database, like DAOs, repositories, or whatever else you're using.Feb 13, 2017
DisadvantagesIt is more vulnerable to failure and data replication or duplication is possible.High dependency between data structure of data store and its agents.Changes in data structure highly affect the clients.Evolution of data is difficult and expensive.Cost of moving data on network for distributed data.
