When should you simulate a data source for a data view?

Simulating a data source for a data view is crucial when the interface with the external data provider is not yet finalized. This approach allows developers to create a prototype or test the functionality of the application without relying on the actual external data. By using simulated data, you can ensure that the application behaves as expected and meets functional requirements, even if the actual data structure or source is still under development.

When the interface is not finalized, it can be hard to predict how the application will interact with the real data, so simulating allows for flexibility and adjustments without the immediate need for the external system. This approach helps in validating the design and logic of the application while avoiding potential delays associated with dependencies on external sources.

Simulating also plays a crucial role in early testing and debugging, enabling developers to identify issues and gather feedback on functionality before the actual data is integrated, paving the way for a smoother implementation later on.
