The document discusses component diagrams in UML. It explains that component diagrams are used to model the physical aspects and static implementation of a system by focusing on its components. It describes how to create a component diagram by identifying all system components, creating visual representations of each, and describing their organization and relationships. Key elements of component diagrams include components, interfaces, dependencies, and ports. An example component diagram for an e-commerce system is provided.

1. Component Diagram
A Detail description on Component Diagram

2. Component Diagram
 Called UML component diagram
 Used to model physical aspect of any system
 Specially forcuses on system componest
 Used to model static implemention of any system


3. How to DRAW ??
 Take stock of everything needed to implement the planned
system.
 For example, In an e-commerce system,
 Take components that describe products, orders, and customer
accounts.
 Create a visual for each of the components.
 Describe the organization and relationships with components.

4. Elements
 Components
 Logical Unit Block of the system
 In e-commerce system a component can be ordering system, customer or any logical block
 Interface
 It is the group of operation required by the component
 Like “payment”,”order”
 Dependencies
 It is the relationship between modal elements
 Port
 Helps to expose the interface

6. Deployement Diagram
 Visualizes the physical hardware and software of a system.
 Shows how the system will be physically deployed on the
hardware.


7. Notations
 Nodes
 A physical entity that executes one or more components, subsystems or executable.
 A node could be a hardware or software element
 Artifacts
 Artifacts are concrete elements that are caused by a development process.
 Examples → libraries, archives, configuration files, executable files etc.
 Communication Association
 This is represented by a solid line between two nodes.
 It shows the path of communication between nodes.
 Devices
 A device is a node that is used to represent a physical computational resource in a system.
 An example of a device is an application server.
