The filters don’t require any knowledge of the working of neighboring filters.

Each filter will work independently and is designed to take data input of a certain form and produces data output to the next filter of a specified form.

Pipes are used to transmit data from one component to the next.

The figure represents pipe-and-filter architecture since it uses both pipe and filter and it has a set of components called filters connected by pipes.

This kind of architecture is used when input data to be transformed into output data through a series of computational manipulative components.

Data can be passed among clients using blackboard mechanism.

This means that the existing components can be changed and new client components can be added to the architecture without the permission or concern of other clients.

This data-centered architecture will promote integrability.

Variation of this approach are used to transform the repository into a blackboard when data related to client or data of interest for the client change the notifications to client software.

The client software access a central repository. The figure illustrates a typical data centered style.A data store will reside at the center of this architecture and is accessed frequently by the other components that update, add, delete or modify the data present within the store.Software Engineering | Classical Waterfall Model.Software Engineering | Requirements Engineering Process.Differences between Verification and Validation.Functional vs Non Functional Requirements.Software Engineering | Coupling and Cohesion.Software Engineering | Integration Testing.Software Engineering | Seven Principles of software testing.
