Which characteristic is NOT associated with controller worksheets?

The correct answer is that controller worksheets are not exclusively based on the data model. While they do interact with the data model, this statement implies a limitation that doesn't capture the full flexibility and functionality of controller worksheets. Controller worksheets are designed to facilitate various user interactions and viewpoints, providing a more comprehensive experience beyond just the data model.

Controller worksheets are indeed characterized by their ability to provide switchable views, allowing users to toggle between different perspectives on the data, which enhances user experience. Moreover, they can consolidate multiple related data views, making it easier for users to analyze information from different angles. These features contribute significantly to how users engage with and derive insights from their data.
