Question

Select types of data-centered software architecture

a. Batch sequential
b. Pipe and filter
c. Blackboard
d. Repository

Answer 1

The selected types of data-centered software architecture are batch sequential, pipe and filter, and blackboard. These architectures have specific characteristics and are suitable for different scenarios.

Step-by-step explanation:

The selected types of data-centered software architecture are:

1. Batch sequential: In this architecture, data is processed in batches in a sequential manner. For example, a payroll system may process employee data one batch at a time.
2. Pipe and filter: In this architecture, data flows through a series of filters connected by pipes. Each filter performs a specific task on the data. An example is a UNIX command pipeline.
3. Blackboard: In this architecture, multiple components collaborate by reading and writing shared data on a common blackboard. The blackboard contains the current state of the problem and is updated by various components.

These types of software architecture are used in different scenarios depending on the nature of the problem and the requirements of the system.
