Component Management - Data Dictionary and Sequence Diagram
Component Management
This documentation provides a comprehensive overview of the Component Management module, including data structures, user interface components, and interaction flows.
The following sequence diagram illustrates the interactions between the user interface, controllers, view
models, services, and the database during component management operations.

actor User
participant UI as Component Details UI
participant Controller as ComponentDetailsController
participant ViewModel as ComponentDetailsViewModel
participant Service as ComponentService
participant Database as Database
participant Notification as Notification System
%% View Component
User->>UI: View Component Details
UI->>Controller: initialize()
Controller->>ViewModel: Bind Properties
Note right of Controller: Binds UI controls to ViewModel properties
%% Create/Edit Flow
User->>UI: Enter Component Details
UI->>Controller: saveComponent(event)
Controller->>Controller: Validate Input
Note right of Controller: Check componentName and projectId
alt Invalid Input
Controller-->>UI: Show Validation Error
else Valid Input
Controller->>ViewModel: saveComponent(componentDTO)
ViewModel->>Service: saveComponent() / updateComponent()
Service->>Database: Persist Changes
Database-->>Service: Return Result
Service-->>ViewModel: Return Saved Component
ViewModel-->>Controller: Update UI
Controller-->>UI: Show Success Message
end
%% Delete Flow
User->>UI: Click Delete
UI->>Controller: deleteComponent(event)
Controller->>ViewModel: deleteComponent(id)
ViewModel->>Service: deleteComponent()
Service->>Database: Delete Record
Database-->>Service: Confirm Deletion
Service-->>ViewModel: Return Success
ViewModel-->>Controller: clearComponent()
Controller-->>UI: Update UI State
%% Error Handling
alt Error Occurs
Service-->>ViewModel: Throw Exception
ViewModel-->>Controller: Log Error
Controller-->>UI: Show Error Dialog

Explanation
This sequence diagram captures the lifecycle of a component within the system, detailing how user actions
propagate through the UI, controllers, view models, services, and the database. It ensures that each step,
from viewing to deleting a component, is clearly defined and handled.
View Component: The user initiates a request to view component details, triggering the
initialization and property binding processes.
Create/Edit Flow: Allows users to add or modify component details, incorporating
validation before persisting changes.
Delete Flow: Facilitates the removal of a component, ensuring confirmation and proper
state updates post-deletion.
Error Handling: Manages exceptions gracefully by logging errors and notifying the user.
