SensorDatabase

1. Purpose

This module defines the foundational view and view-model interfaces for the sensor database feature within the DTS (Data Tracking System) architecture. It establishes the contract for UI-layer components that interact with sensor data, leveraging the existing IBaseView and IBaseViewModel base interfaces to maintain consistency with the system’s MVVM (Model-View-ViewModel) pattern. The interfaces themselves are intentionally minimal—serving as marker interfaces—indicating that sensor database UI components inherit standard view/view-model behavior without additional feature-specific API surface at this level.

2. Public Interface

No public methods, properties, or events are declared in these interfaces beyond those inherited from their base interfaces (IBaseView and IBaseViewModel). The interfaces are:

• ISensorDatabaseView
  Signature: public interface ISensorDatabaseView : IBaseView
  Behavior: Serves as a contract for the view (e.g., XAML page, control, or UI component) responsible for presenting sensor database content. Inherits all members of IBaseView (e.g., DataContext, lifecycle hooks, etc.), though their exact signatures are defined in the base interface (not shown here).

• ISensorDatabaseViewModel
  Signature: public interface ISensorDatabaseViewModel : IBaseViewModel
  Behavior: Serves as a contract for the view-model that manages state and logic for the sensor database UI. Inherits all members of IBaseViewModel (e.g., Initialize, LoadDataAsync, Dispose, etc.), though their exact signatures are defined in the base interface (not shown here).

Note: Since both interfaces are empty beyond inheritance, no additional behavior is specified at this level. Concrete implementations (e.g., SensorDatabaseView, SensorDatabaseViewModel) must define actual functionality.

3. Invariants

• ISensorDatabaseView must be implemented by a type that also satisfies IBaseView (e.g., supports binding to an ISensorDatabaseViewModel via DataContext).
• ISensorDatabaseViewModel must be implemented by a type that also satisfies IBaseViewModel (e.g., supports initialization, data loading, and cleanup).
• The pair (ISensorDatabaseView, ISensorDatabaseViewModel) is intended to be used together in an MVVM binding context, where the view’s DataContext is an instance of ISensorDatabaseViewModel.

4. Dependencies

• Depends on:
  • DTS.Common.Base.IBaseView
  • DTS.Common.Base.IBaseViewModel
    (Exact definitions of these base interfaces are in DTS.Common.Base, not provided here.)
• Used by:
  • UI-layer modules (e.g., WPF/MAUI/Xamarin projects) that implement sensor database screens.
  • Dependency injection containers or view-resolution logic that resolves ISensorDatabaseView/ISensorDatabaseViewModel for navigation or composition.
• Notable absence: No direct dependencies on data-access or domain-layer types (e.g., no ISensorRepository, SensorEntity)—suggesting separation of concerns.

5. Gotchas

• Empty interfaces may indicate incomplete design: The interfaces currently serve only as markers. Developers should verify whether IBaseView/IBaseViewModel provide sufficient functionality or if sensor-specific behavior (e.g., RefreshAsync(), SelectedSensorId) was intended here but deferred.
• Ambiguity in scope: The term "sensor database" is not further qualified (e.g., is it a local cache, a remote API, or a historical log?). Without additional context, consumers must infer semantics from concrete implementations.
• No versioning or extensibility hooks: The interfaces lack attributes (e.g., [Obsolete], [EditorBrowsable]) or generic parameters, making future extension (e.g., adding ISensorDatabaseView<T>) potentially breaking.
• None identified from source alone.
