In what scenario is a keyed data page not necessary?

A keyed data page is primarily used when there is a need to retrieve or display specific data based on key values or parameters. In scenarios where predefined data is being presented, there is usually no need to perform additional filtering or retrieval actions based on dynamic inputs. This is because the data being displayed is static or fixed, thus making the requirement for a keyed retrieval irrelevant.

When presenting predefined data, the system can simply pull the necessary information without the complexity that comes with managing keys, which would typically be necessary if you needed to customize the output based on varying inputs or conditions. In this case, a straightforward data page is sufficient, as it inherently avoids the added complexity of adding and managing keys.

This understanding emphasizes why a keyed data page is not necessary in situations involving predefined data, as the retrieval process does not benefit from the dynamic capabilities that keyed data pages provide.
