What is true about data requirements for a system?

The choice that states the requirements must cover all data handled by the system, even if it is initiated and/or deleted outside the defined system, is accurate because it recognizes the importance of comprehensive data management within a system. Understanding data requirements means considering not only the data that the system directly manages but also data that may be relevant or that interacts with the system from external sources.

In today's interconnected environments, systems often need to integrate with or account for data from various origins. This holistic view ensures that all aspects of data handling are understood, including how data flows into, out of, and through the system, even if certain data operations occur outside its immediate processes.

Additionally, comprehensive requirements enhance data governance, ensuring that all relevant data is considered when designing system functionalities. This is crucial for maintaining data integrity, compliance with regulations, and ensuring accurate reporting and analysis.
