What do you understand by architectural modeling ?Explain its various concepts and diagrams with suitable example. ORWrite short notes on architectural modeling with suitable exampleand diagrams.

Concepts of Architectural Modeling:

1. Architectural Modeling Overview:
   • Represents the overall framework of the system.
   • Contains both structural and behavioral elements.
   • Functions as the blueprint for the entire system.

Diagrams in Architectural Modeling:

1. Deployment Diagrams:

• Purpose: Show the physical relationship between hardware and software in a system.
• Example: In a web application, a deployment diagram may illustrate how servers, databases, and user devices interact physically.

2. Component Diagrams:

• Purpose: Model the static implementation view of a system, representing a high-level packaged view of the code.
• Example: In an e-commerce system, a component diagram may depict software components like shopping cart, payment processing, and user authentication.
• Components:
  • Definition: Physical, replaceable parts of a system.
• Interfaces:
  • Definition: Collections of operations specifying a service.

Component Diagrams:

A. Components:

• Definition: Physical, replaceable part of a system packaging implementation and providing the realization of a set of interfaces.
• Illustration:

B. Interfaces:

• Definition: Collection of operations used to specify a service of a class or a component.
• Properties:
  • Identified by a unique name with an operational pathname.
  • Do not specify structure or implementation details.
• Realization of an Interface:

• Representation of Interfaces:

Deployment Diagrams:

A. Nodes:

• Definition: Pieces of hardware in the system.
• Illustration:

B. Communication Path:

• Definition: Depicts the communication path used by the hardware.
• Illustration:
