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.
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.
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.
Limitations. Lack of tools and standardized ways to represent architecture. Lack of analysis methods to predict whether architecture will result in an implementation that meets the requirements. Lack of awareness of the importance of architectural design to software development.
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.

What is correct about Data centered architecture? Explanation: It is modifiable with respect to changing the functionality of any particular client as other clients will not be affected, Coupling among the client will lessen the effect of data center architecture are the correct architectures.
Data architecture is a framework for how IT infrastructure supports your data strategy. The goal of any data architecture is to show the company's infrastructure how data is acquired, transported, stored, queried, and secured. A data architecture is the foundation of any data strategy.Mar 4, 2021
Data centered architecture: In this architecture, the database is centralized and accessed frequently by other clients which modify the data. Client Server Architecture: This architecture has one or more client computers connected to a central server (maybe a database server) over a network or internet connection.Dec 2, 2018
It helps in risk management, reduces its time to market, and reduces development time. Having software architecture helps you prioritize conflicting goals. It facilitates communication with stakeholders, contributing to a system that better fulfills their needs.Jan 16, 2017
A software architect makes important decisions regarding the software that goes on to define its overall integrity. A good software architecture helps define attributes such as performance, quality, scalability, maintainability, manageability, and usability.Jul 12, 2021
By building effective architecture, you can identify design risks and mitigate them early in the development process. Software architecture dictates technical standards, including software coding standards, tools, and platforms. It gives the right technical solutions to ensure your success.Jan 2, 2021
